this is a good quality very easy to assemble pistol buffer kit for the AR 15. Looks good. fits well. would recommend this assembly kit for anyone building a AR15 pistol. the foam padding is thicker than most other kits and the finish is a dark black anodized look. kit comes with the buffer, buffer spring,buffer tube foam covered, end plate and castle nut.

I am very glad to have picked this up. I was wary on my AR pistol build, having watched many videos that show the potential problems with the weight of the buffer, spring issues, etc. I got this as a starting point and kept my expectations low. I'm glad to report that after my first trip to the range, and after 120 rounds, I had zero problems. This product far exceeded my expectations and I would highly recommend.

I purchased the Phase 5 Pistol Buffer Tube assembly after researching and comparing similar designs. The Phase 5 model I purchased is held in very high regards within the AR pistol build community because of their engineering and excellent build quality. Another benefit is the tubes outer diameter and length which will accept a few models of the slip-on braces from SB Tactical should the end user elect to do so. I invested in the Phase 5 Pistol Buffer assembly as a back-up setup when legal issues were initiated against pistol braces by federal entities. AR pistol design origins began with this design of padded buffer tube and is accepted without reservation by the BATF. I recommended this product to a good friend who also purchased it for the same reasons I mentioned.

In the State of New York.Phase 5 Weapon Systems Inc AR-15 Pistol Buffer Tube Complete Assembly PBT-CA Color: Black, Finish: Anodized, w/ Free ShippingThen I just attach a short but stock to it. The Buffer Tube padding Makes for the Perfect Cheek Weld. I even Think it’s better than the normal AR STOCK. Much more sturdy and no wiggle at all.
