As Advertised


I bought 2 of these kits because they were such a good deal. I have not installed them but they appeared to be well made and come packaged in a plastic bag with all of the parts screwed together (that can be) to minimized damage in shipping.

looks like quality stuff


I can only speak of what this product looks like. i have not installed it on the rifle yet. Even after i do it should be another few hundred rounds before failure might or might not occur. so i speak of the looks right now. looks are great.

excellent customer service


I had never been to PA, but I will get all my gun gear there from now on. Mike was great and made the shopping and pick up experience friendly and easy. Plus, I got quality products at a great price!Definitely my go-to gun store

Perfect fit


I have a stripped Midwest Industries billet receiver, I was able to install everything myself with no issues. I also installed a B5 Bravo stock over the buffer tube with a great fit, but maybe some slight play. Overall definitely worth the buy especially with the price.

Great price and Great fit.


I have an older A2 Bushmaster that originally had the fixed stock on it. This new tube threaded in perfect!

Looks good


I installed this on my latest build. Finish is excellent, and fit Spikes Tactical receiver perfectly. Will buy again for another build.

AR Build Buffer Kit


I purchased a Anderson Buffer kit for building out my AR. The buffer tube is well made and fit perfect. The spring and buffer work perfectly as well. It arrived within just a few days of ordering and was packaged well. No complaints.

No complaints.


Inexpensive but good quality, can't complain one bit.

Inside buffer tube rough, spotty finish.


Inside of the buffer tube mic'd at uneven finish, the larger diameter of the tube was non anodized. Basically looked like a monkey drilled it with a hole saw. Outside anodizing was faulted with spots. All though the buffer and spring were on par.
