I’ve never built a ar and this will be my first time buying a frt, I have a gforce jawbone I want to drop in a frt, a friend told me that they dropped in a kabuto frt in there’s looking it up on yt several other people have done that and got a heavier buffer and jt worked great. But I asked Gemini and it said that a kabuto frt would not work on the jawbone it says a frt on a jawbone is not viable was hoping for some help.

Ive never seen anything like this before. Im assuming there was a failure to eject, but the next round tried cycling in and was crushed inbetween the bolt and stuck round. Ive shot 100s of rounds through my jawbone and haven't had any major problems. I also wasn't the one shooting when this happened so I cant be certain of what happened. Is there a way to prevent this from happening again? I was running glock gen19 magazines.

Recently purchased a PSA PX9 with SBA5 brace and 10" barrel, less then two weeks old and the SBA5 brace is stuck in the closed position. Emailed PSA about the problem so hopefully I can work out a fix but this brace failing already has me thinking I should consider using something different.

First PCC, planning to add a suppressor soon, YHM R9
Wondering what brace/stock is most recommend for similar setup?

Think I have a ACS on my AR10 which is great

Im newish to the PCC world. I got a GFORCE JAWBONE for $450 at my local gun shot. Im just wondering what are some good upgrades im getting a vortex sparc and one mag im just wondering what are some good upgrades and its the 5 inch barrel. Build list there really isn't non There are no upgrades grades yet but the red dot and I got the only mag from when I got it.

Went to the range today and had two incidents where my AR9 went brrt. Two round slam fires.

Lower is a standard lower that had an 11.5” 5.56 upper and had no problems but now I’m using a Stern adapter. Using a Schmid Nickel Teflon stock trigger. Disassembled and found nothing wrong with the trigger pins or springs.

Using a BKF 9mm BCG 8.3 Ballistic Advantage barrel and 8oz buffer and Springco blue spring. When I disassembled the bolt the only thing I could tell is the firing pin retaining pin is somewhat bent and the head of the fire pin is gouged a little bit. Firing pin spring looks ok and not broken.

Very new to AR9s so any assistance would be appreciated.

Hi everyone

I’ve been planning out a build for a ar9 for a while now and blowback9’s website has been super helpful to me. I am particularly interested in using his gentle recoil system but i wanted to get the build as small as possible so i wanted to use the sb tactical hbpdw.

I didn’t see anything on blowback9’s website pertaining to this setup so i thought I would ask here to see if anyone had any ideas on what i could do if anything to improve recoil with this setup.

Also if anyone has a setup with the hbpdw or any other pdw setup i would like to hear what you think about it
