You are correct. It simply unscrews. I had to use channel locks padded with some thin leather to break it free, as it is lock-tite'd in. The barrel is a heavy, thick beast that weights more than the air tube.

Although I don't think I'm getting pellet clipping on the baffles, when I get my leaky air problem resolved I will look further if the Crosman premier domes I've bought group poorly also. I don't see any indication or marks of any kind at the exit to the shroud, but testing without the baffles would certainly tell for sure. Would also be able to get a look at the barrel's crown while their out. Sorry to hear that some don't like the finish on their rifle stocks, it's the one thing I really won out on, my stock and grain is beautiful, even if it's not real select walnut.

Mike, when I tried the t I did t have the air tube for, so it was hard to get a good grip on it. I’m sure I will be replacing the o-Rings again before too long, so I’ll try it again.

Just curious, is there an air stripper at the end of the barrel or just a something that keeps going it centered? When I was cleaning the barrel I know you it was a pain because I kept missing the barrel! Is the piece on the end of the barrel metal or plastic? How is it attached? Does it just slip on? You have my curiosity peaked now! LOL!

Tom, have you tried the H&N Sniper Pellets? My .177 really likes the Sniper mediums! So far they group the best. But, the Benjamin Hollow Points do well also. They actually group better than the Crosman Domed 10.5gr in the box!

Old tip on passing a cleaning device past the LCD baffles is to insert a straw down the shroud to line it up with the barrel.

Thanks James! I have used that technique in the past, not sure why I didn’t think of doing it on this one! Probably anther senior moment. LOL!

Decided to jump in myself, I have the Dar .25 on it's way scheduled to be here tomorrow. Thanks to all the early bird buyers who jumped right in and began to give valuable feedback about their rifles. It played a big part in me getting off the fence and getting one. I was trying to decide whether to break it down immediately and change the 0 rings or just use it until there is a problem. Decided to just use the gun until when or if it develops a leak. We won't know if the quality control of the 0 rings has been addressed if we change them without trying it first. I am still concerned about the unavailability of magazines and parts. I know an Aim sports rep has said it's happening, but then again the cynic in me says "would he say anything else'?

I spoke with Ryan today.
He is waiting on magazines to arrive from China which I understood are already in route.
I am quite confident he will let us know as soon as they are here.
He also told me the Dynamic website is almost ready to become available.
I think he is working very hard to satisfy everyone's requests.

Yes, I have a tin of the Sniper Magnums I bought when I ordered the DAR 22, odd thing is sometimes they will cluster, other times they spread out to nearly an inch even when dead calm outside so it's not wind. The JSB 18.13 do the same thing, they'll cluster, then another mag will spread, still trying to sort this whole thing out. I may try cleaning the barrel again and see if it helps as they did better right after the seasoning shots when the barrel was first cleaned, but have gone downhill since then. Maybe there's more shipping crud in the barrel that needs cleaned out that was missed in the first cleaning. That's something I could do tonight while I wait on o-rings to come.

tracker1955 · « **Reply #429 on:** July 26, 2018, 11:11:46 PM »

Sorry for the late post, thought it went through before I left for dinner. I did clean the barrel again, wow the crud that came out, have always used WD-40 to clean my barrels but maybe I need to buy some Balistol or something stronger, I ran patches through last Thursday until they came out clean, was surprised at how much more filth came out. Hadn't really run that many pellets through it to have so much crud in there. This may explain why some run JB bore paste through their barrels before shooting the first time. Will see if this tightens up the groups now, seldom see a barrel that doesn't like JSB 18.13's. Also anxious to see if it will like the cheap Crosman Premiers, picked up a tin at Tractor Supply last night for under $8 with tax.

Mike, " The trigger is simplicity itself, with only two moving parts and two springs. I've modded my trigger to where it breaks at exactly the same point, at just over a pound. The trick is to reduce the contact area of the pin that comes out of the hammer that engages the sear. Very similar to the mod that folks do to the Varmint/Stormrider."
Question: When you say reduce the contact area of pin, exactly what do you mean, make it narrower, change the angle, round it? I have done a search, and came up zilch. More info would be greatly appreciated.
BTW. +1 on the compressor; sounds like the exact one I have.

Well I wasn't as fortunate as some with my Dar.25. Out the box it didn't hold air. First it wouldn't seal and take any air, I cock it and it finally sealed and started filling. I was excited as I slowly filled to 200 bar. My excitement quickly turned to disappointment as soon as I bled the line and could hear air escaping. The air is coming right back out the fill probe hole. This to me seems like it would be more of the one way check valve in there not closing, or am I off here, and we have an O ring in there that could cause this? Still even though I am disappointed and hope this company does better with this gun in the future, I am thrilled with the looks and feel of this rifle at this price point, if the bugs get worked out I could see another of these in my future.

AS568-117 B90 (NBR) Buna-N 90 Duro O-Ring is what I installed in mine today, they're hard enough to make the regulator fit in there the way it should.

I tried the 70Duro but they were too soft.

Thanks Wayne, read your previous post and have some of both those o rings on the way.

David I also blew out the breech o-ring a while back when I had the regulator turned up too high, I'll probably figure out which ones I need and get those in 75-80duro if they have them from the O-Ring Store. I admit that the shipping from there is on the high side but they have about any o ring you'd want.

I just ordered a few of the -117 Dura 90's from the O-ring Store. The -116's I put on my regulator are still holing air, but they are from one of those Amazon variety kits and I have no idea of what the hardness is, but so far they are holding air. Hopefully, I'll have the 90's before they decide to give out.

Wayne52 · « **Reply #436 on:** July 29, 2018, 02:35:22 PM »

Them 90 duros will do the trick Paul, I put 60 shot through mine this morning with three refills without a problem, accurate too. I see my .177 is still full but I'll bet the o-rings in it give out before long. The really bad thing about these things dumping air is it takes so dog gone much to fill them to 3K with the 300cc tube like they have.

kingrude1 · « **Reply #437 on:** July 29, 2018, 02:55:21 PM »

Well my 116s o rings came yesterday, changed the regulator o rings and both of those on each end of the fill cylinder on my Dar.25,, figured would be enough to get me by until the right o rings get here in a few days. Was a chore but finally got it to take air, filled it up to 200 bar, bled system, pulled probe, this time no air coming out that I could hear, excitement. That is until I check the gauge on the rile several minutes later and could see the pressure was dropping. Well let's see how long it takes I tell myself, it slowly bleeds down to 100 bar at which point I hear a pop in the other room from the rifle proceeded by the dumping of the remaining air. Now what? This is getting old quick, might be time to box this puppy up send it back and try another one!!!

kingrude1 · « **Reply #438 on:** July 29, 2018, 03:46:48 PM »

Update: After muching swearing and promising to throw this rifle in the river, I settled down, went back and took it all apart slowly inspecting everything carefully. I some how got the airtube turned around and had the vent hole down stream DUH. Removed and replaced all o rings again, carefully cleaning before installing. Put it back together "RIGHT" this time, aired it up and it is holding air, fingers crossed that I don't have a leak.

Why do we use standard size o-ring in a metric base airgun
