Title: 2nd Gammo Urban lemon
Post by: RAJOD on April 23, 2018, 03:27:13 PM
The first urban I got had a broken gauge so I exchanged for another.

The second one shoots well, 820-840 fps jsb 15.9, is accurate but.....

I can't zero it at 30 yards.   I tried two different UTG 30mm tubed scopes and it maxed out the vertical adjustment and still shot 2 milldots low at 30 yards.   

It either has some serious barrel droop or possibly the moderator is causing the pellets to drop low.
The barrel band might be pulling the barrel down.  There is space at the bottom of the band but the top is pressing on the barrel some.    No easy way to fix it unless I cut the band off (and that might not fix it if its the LDC) and the LCD does not unscrew, its like glued on.

Unless someone has an easy fix I might have to send it back.

The 3rd was the keeper for me, 1st was accurate would not hold air, 2nd blew the end off on the second mag.  This third one is doing well, like the gun but I don't think the BSA builders have figured out quality checking on assembly line build rather than a single assembler doing the whole unit.

That was pellet clipping.  Either due to double loading (2 pellets) or the LDC was a little off center from the factory and it clipped it.

I just put in a order for a 3rd urban, fingers crossed it works ok.

I just ordered an urban minutes ago. Hope it goes well. I paid a little extra to go through PA as an insurance that they are easier to work with if I get a lemon. Fingers also crossed.

have you tried a different brand scope/scope rings? I took the BNM breech off my Maximus and remounted the UTG scope, I ended up having to keep the shims in the back ring. On a hunch I tried it on the Urban and yep, still had to keep the shims. That's the only scope I've had to shim, the others I've tried, a Hammers and couple of cheap CVLife, have not needed them.

Yep... looks like double loaded pellet... it's easy to do. If you "stutter cock" the gun... by that I mean if you pull the bolt back and it don't catch the sear and you pull it back again it will double load unless you pull the mag before pushing the bolt in for the second time. I have to watch Betty Lou when she cycles the mag because she sometimes don't pull it back far enough to engage the sear. If your LDC was off center far enough to do this, I highly doubt you would have made it through the first mag successfully.

And making sure it is all the way back is especially important if the trigger has been adjusted very fine with a change to a longer adjusting screw.

One other complaint I have with the Urban. It will let you cycle the mag after it's out of pellets. I had to mark the mag with bright yellow paint marker to show the "last shot" position. Don't get me wrong, I love my Urban... just a few annoyances.

I was fairly certain it was, shot the first mag inside over the chrony.  Stepson who is fairly experienced was certain it was not a double load... But have experienced it myself and think he just didn't recognize it happening ... back to Walmart it went... The 3rd has shown no signs of issue to date

No no one is easier to work with than Amazon.    Not PA not anyone.    Trouble is with Amazons shipping department.   
I had that urban for 4 weeks and typed to amazon rep yesterday and I will have a new one tonight.   

The urban issues has ZERO to do with Amazon and everything to do with who Gammo hires to assemble.   For 220.00 or so the Urban is a great gun its just a craps shoot getting one without small issues like a sticky gauge,  or pressure on the barrel band etc.

PA does seem to package better though.    If I was forced to keep mine I would either buy a drooper UTG mount or cut the barrel band off and see if that brought the shots up.  But on a new gun you should not have to tear it apart and break warranty to fix.

Me too Phil. Another member bought 2 of them and sold me one for what he paid. It came to me triple boxed just like he got it. I have done nothing to the gun at all except for scope, fill and shoot it.

Post by: Xraycer on April 24, 2018, 10:59:27 AM
My Urban worked perfectly for the first 4 weeks, straight out of the box. Last week, out of the blue, the bolt and magazine went out of alignment. Judging from the oring on pellet probe, there had always been an alignment issue, because the oring was all chewed up. Appears the alignment got much worse because now it was really binding when the probe goes through the magazine. Without the magazine, the bolt probe goes into the barrel, smooth as butter. I've tried wiggling the mag around, while trying to advance the bolt, but there isn't much play......so, no point in trying to shim anything. I'll keep messing with it to see if I can resolve the issue. If not, it looks like I'll be loading pellets with needle nose pliers indefinitely, because there's no way I'm paying $50 for another mag!

On that note, I actually liking this gun a lot! Especially because I only paid $200, for a very, very good shooter.

Call Gamo, they'll replace the mag.

I had the same issue on mine, to the point the Oring finally broke off. I originally went thru the web site for support back in November, spoke with the customer rep a couple of times through email and was promised a new one. It never arrived so I called a couple of weeks ago on a Friday. Had the new one on the following Wednesday.

For what its worth, mine is actually much more accurate without the O-ring. The binding seems to deform the pellet skirt when seating. I only bench shoot so ended up taking the O-ring off the new mag and hold my finger over the hole when dropping in the pellets. The last pellet stays in place long enough to put it in the mag well and the loading is smooth as silk.

Thanks for the heads-up, Todd!

Now, you're referring to the oring on the magazine, I'm referring to the oring on the probe that's part of the bolt. My probe is catching before it can even enter into the magazine.

Gotcha. Yes, the one on the mag itself is the one I'm talking about. I should probably take a look at the one on the probe as well.

In response to the issue, I removed my barrel band months ago and having the barrel free floated has definitely helped in accuracy, as has adding a regulator...

Yes I tried two sets of rings, even reversed then in case one was higher than other.  Three scopes.  Nope none of it did a thing.    Its a low shooter.   I'm thinkings its the barrel band pulling the barrel down.   

But everything else on the gun is good.   It cycles well, shoots well, trigger is fine.  Its almost a keeper.

I cut the band ff easily with a hobby knife (barrel section, bottom section slides off if you remove Filling Valve and Gauge Housing (empty air tube))

The Urban is mechanically a BSA Buccaneer...

Nice!  So around $105.00 USA for the regulator.   Brings the urban up to 220.00 + 105 = 325.00.

Guys after following several threads about the Urban, it is apparent a fellow either gets a keeper OR not right outta' the box. I finally have had some decent weather here in the mountains to do some testing.
Discovered no way to zero a scope on it. I tried several scopes & rings with same crappy results. I started looking a little closer and found the barrel & band were tweaked tightly to the right! They were off the center line by almost 1/4". Flimsy sort of arrangement there. Check yours if in doubt.As soon as it appears warranty won't be used,The barrel band and junky moderater will be replaced. At this moment,I'm happier with it than at first glance. A keeper I hope !

Yes I think that barrel band is a big issue on some.   I think a barrel band is good to have for the times when you bump the end of the gun and its going to give and put pressure on the where it enters the breach.    The band does some good in that situation.   But it does not need to be a tight band for protection.   They should make the part around the barrel larger so there is a gap that the barrel does not touch.  The only time it would touch the band is if you bumped it hard enough to flex the barrel.   They have it so tight that it holds the barrel in the flexed position.   So people either cut off the band or send the gun back

Darndest thing. Yesterday, after shooting the Urban for awhile, I decided to mess with the magazine again. I did nothing to it, except loaded it up............low and behold, the bolt probe is no longer catching on the magazine. Shot all 10 pellets through the mag, and all the shots were true.

They are molded on into grooves in the barrel. They have to be destroyed to get them off. There are two pins in the end cap that can be removed to get the very end cap off. This exposes the insides if you care to modify for what ever reason. I haven't found any need to do anything to mine besides shoot and enjoy.

The portion you are seeing is from the internals, it has an end cap affixed via two small but long roll pins on the very end as shown in the pic with the cap. 

I have no idea how the barrel is affixed to the moderator, it does appear to be solidly glued and would likely require destructive removal.

If I were going to do any modifying I think I would take the pickle off and enlist someone to make me a full shroud with incorporated moderator. I've seen a couple examples and they really do improve the looks of the gun.
Here's my thing.... I have $238 invested in a gun that surprises me every time I shoot it so, if it ain't broke... don't fix it.
Title: Re: 2nd Gammo Urban lemon
Post by: avator on April 25, 2018, 11:56:12 AM
OH, I've also considered sacrificing one shot per mag. The purpose would be to plug the last pellet position in the mag. That way the bolt won't close indicating I have fired my last round.

WOW!  Sounds like the Urban fits well in the lottery category.  I have only heard good things about them up until this thread.

I still think the Urban is a great gun for the price.   I think many people keep them with defects and fix on their own.

I could have kept my first one but it had a broken gauge and did not want to pay 50.00 for a new gauge.
2nd one shoots good.  I could keep if I am willing to live with it shooting 2 inches low at 30 yards with the scope turrets maxed out.    FX ($75.00) no limits mount would have fixed it or maybe cutting off the barrel band.   

Its a very nice gun for the money and maybe due to the low price quality control is an area that gets sacrificed.   

So they are sort of like a lottery.   

I think if a modder buys one he most likely will be able to live with ones that others send back.    Some guys tear any gun apart and tinker to improve over stock.

I will say the ones I have shot grouped well, much better than the 25 yard groups shown on pyramid air site.

I still recommend it for anyone wanting to get into PCP.    Great bang for the dollar gun.   Its is not far off from a $700.00 BSA Scorpion SE probably shoots as good just cheaper on trigger and stock.

That is not a bad idea.   The guantlet does that.   If you try to cycle for the 11th shot you physically can't.    I really like that feature even my Daystate XL gets double pellet shot often.

Post by: avator on April 25, 2018, 12:06:10 PM
Yep.... my Mrod and SPA guns are like that. When the mag is empty the bolt won't cycle. I know there is a shot indicator on the mags but, my eyes are too old to see it. I did add some yellow paint marker to show last shot position but you have to look at it each time.

Mine shoots jsb 15.9s the best around 815 ave 810-846 for like 28 shots.   

How much veleocity did you loose when you installed the reg?    Stock mine would shoot those 14.35 grains at around 865 fps.

I would like to keep my 15.9s above 800 fps.     Which means I would probably not get your 40 good shots.   Maybe 35?

I probably only really get 20 good shots +- 10fps the rest are -+ 20 fps

Yep.... my Mrod and SPA guns are like that. When the mag is empty the bolt won't cycle. I know there is a shot indicator on the mags but, my eyes are too old to see it. I did add some yellow paint marker to show last shot position but you have to look at it each time.
Yes those markers sound like a great idea.  In real life I don't often look and often shoot a blank shot on the 11th same with others I shoot with.   

Its actually a small feat to do a 40 shot chrono without shooting an airball the muck up the results.

Not only that..
In a hunting scenario, It's nice to know your not shooting blanks at your intended target.

WOW!  Sounds like the Urban fits well in the lottery category.  I have only heard good things about them up until this thread.

I still think the Urban is a great gun for the price.   I think many people keep them with defects and fix on their own.

I could have kept my first one but it had a broken gauge and did not want to pay 50.00 for a new gauge.
2nd one shoots good.  I could keep if I am willing to live with it shooting 2 inches low at 30 yards with the scope turrets maxed out.    FX ($75.00) no limits mount would have fixed it or maybe cutting off the barrel band.   

Its a very nice gun for the money and maybe due to the low price quality control is an area that gets sacrificed.   

So they are sort of like a lottery.   

I think if a modder buys one he most likely will be able to live with ones that others send back.    Some guys tear any gun apart and tinker to improve over stock.

I will say the ones I have shot grouped well, much better than the 25 yard groups shown on pyramid air site.

I still recommend it for anyone wanting to get into PCP.    Great bang for the dollar gun.   Its is not far off from a $700.00 BSA Scorpion SE probably shoots as good just cheaper on trigger and stock.

I agree, The price is right and there are many guns that need a little TLC once out of the box based on reading the forums.  I most likely would've purchased an Urban over my Marauder back a few years ago when I bought my first one to save some coin.  Marauders where ~$600 back in the day with a hand pump and were the cheapest multi-shot PCP at the time of my purchase.  Kinda glad the Urban wasn't available back then though.

Yea the Maurader is a step up in quality.     I got my 3rd Urban today.    I might keep the second one.

This one is better up and down.   The barrel band is just too tight on these.   If you push the barrel say 1 inch to the right and let go.  It will snap back maybe 1/2" and the band will hold it in a new position which could be 6 inches off at 20 yards.     

I think it might be best to just cut off the barrel band and float it.

Also the new one does not cycle well.  When you push the clip in it goes in maybe 1/8" too far which causes the probe to catch the edge of the hole.  Just have to push the magazine left a tiny bit and it lines up.   This why people are tearing up their probe Orings.     
Its due to them getting cheap and removing the centering peg (which the BSA scorpion has)  With no centering peg the clip hits a (Plastic) piece on the right side of the gun.    On the new gun that plastic piece is flexed out maybe 1/8" more than it should be.   I can fix it with a shim or something. 

So I'm deciding, keep the second one and cut the barrel band (hope the barrel pops up enough where I can zero a scope at 30 yards.   Or maybe swap that plastic side piece for better cycling.

Will take it out tomorrow and see how it groups.

From my experience I think most of the urbans are going to have small issues out of the box.

The barrel band was a dumb idea they should have floated it.   Or they should have made the band so you could easily remove it.  It might help in shipping to have it on.   

I'll guess that 50 percent of the Urbans will have the cycling issue or the barrel band issue.  Both are fixable and livable.    Its due to cost cutting measures.   

Thing is to get much better you have to pay 500.00+ at this price point I guess its expected.

All three have been accurate which  is what counts.    All three did not leak, or have trigger issues.

So they got lots right with the gun.   

I think I'm about finished with my low end guns experiment and moving back into Daystate land again.  Wanted to see how close the low end guns are to the better ones.

Accuracy wise they are not much worse.   

For your first PCP Gammo Urban gets my vote even with the minor issues.    If you end up liking PCPs then you can save pennies for a Daystate or Fx.

I ended up cutting off the barrel band.   Once I did that the barrely poped up and the scope could be zeroed easily at 30 yards.    Its perfect now.    The barrel works best fully floated.

The problem was the air tube is not parallel to the barrel.   The end of the tube by the gauge is further from the barrel than near the breach, not sure why that is but that made the band pull the barrel down and hold it.   

The barrel is thicker than most air guns, it does not flex much.    It like the BSA scorpion, so thick it does not need a barrel band and works and shoots better without.
