Jason

Thank you,
This spread sheet works for me now.

I couldn't get your other spread sheets to open/work for me.

And I have MS Excel on this plastic box.

I greatly appreciate it.

Tia,
Don

Anyone else notice how easy the stocks on these get dinged? It seams that every time I take it out, it has a new ding! I sear I don't beat them or use them as baseball bats! These will definitely be refinished this winter, Tru-oil is much tougher than the finish on these air rifles!

Wayne52 · « **Reply #182 on:** September 07, 2018, 03:43:31 PM »

Wow Paul yours is dinging up bad, the finish hasn't scraped off a bit on any of mine yet. I've got a few small dents and dings but the finish wasn't affected

Wayne52 · « **Reply #183 on:** September 07, 2018, 03:49:25 PM »

Paul that almost looks like you scraped it on a painted surface and the paint rubbed off

Rat Sniper (AKA: PaulT58) · « **Reply #184 on:** September 07, 2018, 03:53:07 PM »

Nope, it hasn't touched a painted surface, this is most likely from taking it in and out of the safe. I even have cloth covers on my rest so the rubber doesn't even touch the stock. Good an excuse as any to refinish it I guess...

Wayne52 · « **Reply #185 on:** September 07, 2018, 03:54:45 PM »

Have you tried rubbing that with a wet rag or paper towel?

Gertrude · « **Reply #186 on:** September 07, 2018, 04:12:19 PM »

Perhaps spraying the new stock with a clear or satin spray might help prevent these marks ?

Wolverineshooter · « **Reply #187 on:** September 07, 2018, 05:58:57 PM »

When I got the two DARs I immediately noticed that the stocks are light weight, and the grain patterns are weak (no grains running the butt to the front uninterrupted) in the neck area, and suspected if they are truly wood. What you guys think?

I had been very carefully in handling them and have shot only 177 for less than 10 shots.

Hope we have a way to make it tougher to take to the jungle

Here's what mine looks like without the butt pad, it's beech I think

but even beech looks decent with a good stain. I actually like the way it looks on my SPA M16, it's not walnut but it seems to be good hard wood.

I have not tried wiping it down, but will. My DAR25 started leaking again. I pulled the air tube and did the condom test, and within minutes it was apparent the valve was leaking. I degassed it and when I looked at the end of the valve I could see the spring was all the way to one side.

I e-mailed Ed at Aim Sports yesterday, following up on my request for a new cone shaped spring I sent last week. Still no response... I'm willing to pay for the spring if they won't provide on under warranty. I also am willing to pay for a new Shroud Retainer Collar and a new valve spring retainer plug. This will get my DAR25 where it should be...

Anyway, I backed out the brass poppet guide and added a drop of blue loctite to keep it from moving. I also drilled a small hole in the center of the valve spring retainer plug, tapped it and screwed a short screw into the hole. This holds the spring in the center of the plug so the valve spring doesn't drift off to one side causing the poppet to be misaligned in the valve opening, which is what I suspect was causing the leak. Anyway, I aired it back up, did the condom test again, and it seems to be holding air again.

Now for a question... I forgot to remove the electrical tape I put over the regulator air vent hole, what if any effect will that have on the performance? I shot a few pellets through it and it seemed to work fine. I just need to remove the stock again to take it off, but was curious as to what would happen if I didn't???

DARs are gone from SG site.

Wayne52 · « **Reply #191 on:** September 07, 2018, 11:01:03 PM »

Yep they're gone now

My guess is,
it would prevent the regulator from properly venting, thus getting variable velocities from shot to shot ? ? ?

Wayne52 · « **Reply #193 on:** September 08, 2018, 05:52:37 AM »

With the sudden change after a discharge of the plenum the o rings on the regulator probably do flex to a certain point I gathered that was why a vent is required.
I wouldn't think that the neutral groove on the regulator is supposed to get any pressure from either regulated or unregulated side.

Well guys I got time to tune my 22. Now I get over 3 mags at average 855 FPS , 34 fps with a stdev of 2.6. May be more, but thunder and rain put an end to my string. Could not be happier. That’s with 21.14g barracudas.
Thanks, Jason for walking me through.

Still waiting to find out what is going to happen with the 25. Guessing tomorrow I will call and ty to find out. They got it last Thursday. Going to try a one mag power tune on it. Anyone what’s to throw me some ideas please feel free.

Really like these DAR guns sorry to see them go. Sure hope to find parts somewhere or might have to make some.

nervoustrigger · « **Reply #195 on:** September 09, 2018, 09:50:58 PM »

James, that's great news. I'm glad to hear you got it set up and that it's making good power.

Did you dial up the regulator or leave it stock, and did you happen to note how much you shortened the hammer spring?

Gertrude · « **Reply #196 on:** September 09, 2018, 10:02:31 PM »

Jason,
Thank you for the fine work you have done in starting to tune the DAR's.
I ha e been pretty busy this last couple of weeks, and haven't had time to put mine back together yet. Hopefully I'll get some time on it soon.
I'd like to get my .25 tuned in around 60 fpe, with whatever efficiency can be squeezed out at that power level.
Keep up the good work !

Lastdog · « **Reply #197 on:** September 09, 2018, 10:26:34 PM »

I had turned the reg one turn ccw when I first got the gun and put new o-rings in, so I left it that way. The hammer spring was so easy to turn with very little resistance I just turn it all the way in then out one turn, tested then out 1/2 turn, tested then out 1/2 turn, test, then in 1/4 tested, and that’s where I stopped . So 1 3/4 out. Did not even see the spring. Is not like my 25. It would take a lot of force to turn so I just left it alone and kept it at stock. Did not think of cutting. I am sure the used different parts on different guns,especially the 25. If I remember right the 25s had the most problems.

Wayne52 · « **Reply #198 on:** September 10, 2018, 02:17:41 AM »

All three of mine are working good now, I've had a lot of shooting time with both the 177 and the 25 but next will be the 22, I need to sight that in with another scope that I have on it, other than that it's tuned good and ready for some of the cast pellets when my mold gets here tomorrow

Today I spent a lot of time with my Airmax Dominator, which kind of fizzled out on me, I need to get some o rings for it an other odds and ends before I get it back up to snuff. PCP's all need maintenance from time to time for sure. I think the most reliable of all the PCP's that I have has been my Prod, that thing is one durable little sucker.

Wolverineshooter · « **Reply #199 on:** September 10, 2018, 04:40:50 AM »

Wayne hope nothing major on your Dominator. Hate it when something gives you trouble here or there.

Glad your DARs are kicking well.

Thank you to our advertisers!
