DAR Gen II is now available

I just got off the phone with Joe at Aim sports , he said they are going to replace my whole air tube assembly on my .22 ... another thing he said they are having issues with the bleeder screw ball that it seals against , he said when you loosen it to bleed the air pressure down  to just crack that screw open as little as possible to leak the air pressure out of the  gun , because the ball can come out of place ,and get deformed trying to tighten it back up ,....  now my .22 had this issue and it/ little ball was deformed ,and it won't seal properly after that ....  I was able to seal it up with that problem using plumbers  tape ... so just barely open the bleeder screw to make it slow leak the pressure out to avoid this issue ...

Mine did that i just used that itty bitty o-ring in the pack it came with.
Not a problem since.

I do not know where that o-ring goes, but it fits and it works good.
I just dropped the oring in and dropped the little ball on top of it. Don't  have to tighten it very much with the o-ring in.

How long will that last? Don't know,  but i have degagassed it at least a dozen times with the o-ring in.

I followed your lead and fixed mine the same way. What's that little o-ring for anyway?

Not a single clue. It just started leaking and I remembered that little  o-ring in the bag and said if it fits, it obviously goes there.

Occam's razor I always say.

I'm staying away from cross-posting here so this is NOT one of the pictures already posted, I promise!

I am working on opening up the stock so I can adjust the hammer tension on the fly in the new to me, .25. I'm having a devil of a time finding the place where I get the best accuracy. Hoping this will help.

Yep that's the exact same thing that happened with mine except the screw wouldn't come out and that's the last that I messed with it, I did try an easy out on it but it didn't work.  I was going to try liquid steel on it to seal it up completely but never did.  I'll have to get hold of him and let him know what happened.

Yes that was a design issue not your fault , and not my fault Joe told me over the phone , also they are going to replace the o rings on all the new guns going out at this point , so it doesn't turn in to more of a mess to deal with customers returning more guns for o ring issues ...

WOW David that looks like a lot of material you removed there. I know it was mentioned something about thumb placement and that is subjective and not for me. Old Army in me dictates to wrap the thumb around and no place for up and or over in any combination. I know it may work for others but not for me, however I may hog out some material to adjust it. I would rather purchase an aftermarket cap with a hex in it and only drill a small hole in the stock for an allen key.

I opened mine up a bit also for an ssg.

But all you would have to do is cut a slot in the cap so you could use a small flat blade screwdriver. Then drill a small hole in the stock to adjust it.

Why can't the Hammer Spring adjuster just be tapped/drilled for suitable set screw, dead square center,
Loc-tited in and then drill a hole or small notch cut in the stock where needed?
Should make for a cleaner install....

I'll call Joe/Mike in the AM and see if they (DAR) have a diagram and "O" ring list posted yet,
I don't hold out much hope, for positive results.............

I just have to decide which brand, I am going to get to go with my other AR's, Sentry or Gauntlet,
I am getting all 3 cal's in the same in the same brand name/model etc.

I do like the SSG mod how did you do it exactly?

That is a nice option.

Heavier spring from McMaster car.

T-nut, screw and nylock nut from the local hardware.  Easiest ssg I've put together.  On my .22  50 shots @900fps with crosmans or 43 shots at 900 with jsb 16's.

[Insanity]

That has got to be one of the simplest SSGs to make thanks for sharing that, I may just do that. I have a .25 spring would you care to measure yours and I will measure mine to see if there is a difference?

Very nice numbers there. You should sell those.

The camera angle makes it look a lot deeper than it is, still plenty of wood there for strength. You can drill and cut a hex opening yourself with an arbor press. You just hollow grind 0.001" off the shank of a shortened hex wrench except for the very end and press it through (straight) the round hole you drill.

Long range PB shooting from a sled, you never wrap your hand around the stock, its the pointer finger pressure only and your thump needs to rest somewhere without cramping it so the thumb generally remains straight so you dont inject your heartbeat into the shot. For tactical shooting.... well, its always a handgrip, never a horizontal grip like you find on wooden stocks. I feel much more comfortable with a thumb notch in this case.

I'm way too new at this, what is an SSG? 

[HunterWhite]

Guys, I've been following this from the beginning,  very interesting.

Rod, Nice SSG you've made there!

Here's the thread on the" Stopping Spring Guide ".

Okay, I just checked,  there are 959 posts in that thread, I will give a summary.

SSG: the Stopping Spring Guide.

In a Precharged pneumatic air rifle the valve is held shut by a small spring, and air pressure.

The hammer spring slams the hammer into the valve actuator, but the air pressure oposses it. It's a spring and heavy mass against a spring and mass. This can bounce a few times. The pellet may have already left the barrel,  so it's a waste of air.
The SSG prevents this waste of air so you get more shots from the same amount of air.
In Rod's example the spring can compress when cocked. When the trigger is pulled the spring can expand until it is constrained by the T-nut to nynlock dimension. This will prevent hammer bounce.

David, I shot Service Rifle and 3P Smallbore for many years and grew accustomed to wrapping my thumb around the grip and did this with any and every long gun . Only recently did I acquire a "Chassis" long range rifle and started using the starboard side thumb grip, it do work. Now I pretty much use that grip with all long guns but shotguns.

Would you be so kind as to link the spring?

I dont have a shop so home jober would be a set screw held tight with loctite. I dont shoot like that so no grip changes for now.

Thanks rod I'll measure my stock spring soon.
