New Umarex Gauntlet Regulated PCP Air Rifle Announced

[grand-galop]

I am sorta interested in the new copper .177-.25 pellets. Sound like a very good hunting pellet wonder when I can get my hands on some.....

They kinda replicate the 9mm RIP bullet..  If you make a search, you will see how DEVASTATING this desing is..

@ AirFiend

No disrespect intended here. If you really are taking 10 minutes to hand pump your pcp you must have a faulty pump. I use a Benji pump to achieve same fill in about 3 minutes and I am twice your age and weight 164#. I recommend you check your seals on that thing.

As for this rifle, only thing that keeps me from pre ordering is the listed weight. I just sold my Synthetic MRod because it felt too heavy to me relative to my Benjamin Maximus and my Hammerli 850. I already miss the repeater on the MRod, so this gun is squarely in my sights, pun intended.

i just picked up some copper .177 the other day. Not sure how they shoot yet.

Sounds like the pressure release key for changing tanks dumps the remaining air in the tank.  Not that big a deal for me because I would not swap tanks.  It could mean a lot of extra effort for those who hand pump.

Trinity makes a tank shut off that isolates it before you begin to remove it. Here it is mounted to a plenum I just finished for an 850 Hammerli. It is ASA Male to ASA Female... I modded this one to 1/4" NPT Female.

Eric,

Are you cutting the stock away to get to that knob (or more likely fitting the action to a custom stock...  )? Just put one on my 850 low power HPA conversion, my goodness was it a knuckle scraper.... Fix was easy tho: http://www.gatewaytoairguns.org/GTA/index.php?topic=119010.msg1169186#msg1169186

I like your plenum idea.... sticking that one in my hat in case I ever want to seriously bump the juice on my 850.

Kevin,

The customer is taking care of that. I was given an OAL, and some serious cash. He has some skills, and is a GTA member... he'll be posting the whole deal, and we're expecting some pretty substantial numbers.

You can bet I'll be making something very similar for the Gauntlet. Already doing all the homework possible, given empty hands atm. Looking forward to May, that's for sure...

Edited... "Thanks", Steven!

[stalwart]

Kevin... great thread, BTW...

Thanks Eric. It's been a lot of fun, and so far even more fun to shoot.

Yes it does...

Not should be better to dump air pressure also inside the gun itself for few shoots  ?
Also one additional 1/8 quick fill pin  for remote connected tank whit 2200 PSI reg. can help  ?

I do not believe  that  1100 PSI is enough to reach  1000 FPS.

Eric,
If I got my measurements right, it should end up just about like your custom knob, maybe just a tad lower.

This is where mine ended up at...just realized I never posted my print over on my other thread...

Then what's the hold up? Let's shoot sumthin'!

[StevenG]

Kevin,

The costumer is taking care of that.

What kind of costumes does he have? Do you have one picked out yet?

[stalwart]

I'm thinking giant squirrel! What could go wrong??

A pox on your house, Steven! I can read gibberish, but I have been known to scroll many screens to rid my posts of simple typos (political threads). If I can prove you knew that, and are trolling me... I'm not gonna like you any more!

Where's the "screw you" smilie? Grrrr...

[fsae99]

I meant that the knurled portion of the on/off valve should be about the same height as your custom knob. The nice thing with the on/off valve it only de-gasses the gun not the tank.
I like you counter sunk the baker adapter and still the air flow was restricted through the 3 hole mod of the valve compared to no baker adapter. This plenum mod will have no restriction.

This is where mine ended up at...just realized I never posted my print over on my other thread...

I'm following you now. That plenum idea is sweet, wish I would have thought of it! The limited amount of regulated air in my setup would definitely hamper any sort of efficient AND powerful build I think (though IIRC Bob was getting 1.5ish FPE/ci @ 33 FPE I think).

Assuming your 850 is the build Stalwart is talking about? Anywhere near posting some numbers on it? Intrigued to see how well it does.

Sorry for hijacking the thread!!

[Rodeo]

skorec brings up a very good point.  1100 psi (76 bar) seems too low to achieve 1000 fps even with light pellets.  I have not seen any posts here or elsewhere with a setpoint that low.  Anyone have experience with velocities near this psi?  What psi do co2 powered guns run at?

[nervoustrigger]

FWIW, I have a QB79 with its regulator at 1000psi and it runs 7.3gr pellets at 950fps, and that is without all the flow tricks to wring out the maximum velocity.  So Umarex's claim isn't altogether unreasonable but if I were a betting man, my money would be on the Gauntlet won't do 1000fps with a 7gr lead pellet.  As usual, it's a weak marketing claim without sufficient information to hold them accountable when the real product hits the shelves.

Saw this and thought it might be of interest to some here: http://hardairmagazine.com/news/umarex-gauntlet-sets-new-standard%E2%80%A8-pcp-air-rifle-performance/

Umarex USA Inc. has announced what they claim to be a major breakthrough in regulated Pre-Charged Pneumatic (PCP) air rifles: the Umarex Gauntlet. Umarex says that the Gauntlet offers the performance of $1,000+ PCPs for an MSRP of just $299.

Looks like a great, regulated, repeater at an affordable price .  Perfect entry level PCP, repeater for Non-tinkering folks .
Should remove much of HPA conversion risk on the QB78's and QB79's and put a dent in "You Know Who's" product demand .

[StevenG]

I think you are absolutely correct, but I think lots of tinkerers will want them too. Adding plenum is something discussed in this very thread and someone will surely make a big bore out of it.
