Great fit and price
I got it for my Anderson build shipping was fast as always the fit is perfect my only complaint is the color. It's not black so it doesn't match my pistol but I still like it. Just bought a shockwave to stabilize it and to the range I go when it comes

not great
Bought this to build a poly lower and the bolt plunger got stuck right off the bat. The buffer tube will not reach the buffer retainer to hold it in place! Not by a little bit either it needs several more turns to make it. Not a happy camper right now.

Great buy
Great product was skeptical at first with kit not having castle nut but I've put a couple hundred rounds down range great buy on sale!

excellent for what it is
this fit my Anderson lower perfectly. The color does not match at all the tube is grey in color and my lower is black. The quality of the tube and finish make up for the color difference. I'm very pleased.

Very nice buffer tube
I bought this pistol buffer tube kit 3 months ago and used it to build out a Spikes lower receiver. It functions perfectly and I really like its appearance. Thank you PSA!

It's ok nothing great though
Purchased this because it was on sale for 29.99. Glad I didn't pay full price for it. It does what it's supposed to do but cosmetically it has issues. The end plate was rusty when it arrived the buffer has multiple scratches and the PSA logo on it is off center. For the sale price it works but don't have high expectations for this kit.

Great Deal
Used this on my 300 blackout pistol. Works great and looks great. The PSA Sling Mount Latch Plate offered a slight challenge. Liked it so much I bought another. thanks so much.
