You will probably need the buffer you linked and a Springco orange spring. You may need to also drill out the gas port. Most PSA's also have a gas tube that is a bit short. The PSA rifle I bought had a rifle stock so that recoil system was good to go. I did replace the gas tube w/the proper length tube from Armalite. I also changed to a carbine stock and used Armalite's buffer tube and buffer w/Armalite's spring. See if it works first. Lots of lube on the bolt carrier group. If I do end up needing it would the spring the guy sells with the heavier buffer be okay instead of the Springco? Quote Link to comment Share on other sites More sharing options...
shooterrex Posted August 26, 2022 Report Share Posted August 26, 2022 If you go with what heavy buffers recommends you should be good to go. Quote Link to comment Share on other sites More sharing options...
Cruzie27 Posted September 7, 2022 Report Share Posted September 7, 2022 I ordered the 18” version with the collapsible stock. And thanks to threads like this I had everything I needed when I brought the rifle home. Ditched the AR-15 recoil setup & short buffer in favor or the Armalite carbine receiver extension kit, and added the normal length XH buffer. Also removed one of the two o-rings that were on the double extractor spring. My rifle will have a suppressor living on it full time so I left the slightly shorter than it should be gas tube & smaller gas port alone for now. Swapped out the regular charging handle for a PRI Gasbuster while I was at it. When I finally got the rifle out it ran perfectly once I got the gas dialed in to the ammo I have on hand. Got to love a rifle that shoots clean, recoils lightly and hits whatever I point it at. Quote Link to comment Share on other sites More sharing options...
