    I bought 2 of these, only one from this site, the other privately. I think these are the best lowers you can buy. It fits great on my older sabre defence, and psa uppers.

    These lowers our just outstanding. We have six rifles with them now. The fit and finish are top-notch. The trigger is superior. We have had no issues after much hard use. We especially like the closed trigger guard. These are the only lowers we use now. You can find them on sale for as little as $139.00. Customer service is great. Questions and emails are promptly answered. Highly recommended. :Cogito,ergo armatum sum!”

    I bought one of these at a gunshow in SC last weekend. I was excited to mate it with my other upper sitting in the gun cabinet. It is unbelievable how unreliable this lower is. The trigger sear is constantly jamming behind the full auto disconnect, which locks down the safety. It jams to the point i have to split the gun and physically pull the hammer from behind the disconnect. It has nothing to do with the upper. I would not give this lower to my worst enemy.

    I bought a complete Magpul lower for my 6.5 Grendel 24-inch Overwatch and dressed it with a great Leopold Mark 4 optics. Works great every time. I will use the lower to practice a bit with my 300 blackout upper. Fits and works great with everything. I have even mated it to my Colt M4 upper, Armalite National Match bull barrel upper, and Delton 20-inch barrel kit upper. Zero problems in any of my configurations. I’m buying at least one more to mate to my 300-blk upper so I have a dedicated pairing. Looking to build a couple of AR’s with Wylde chambered barrels, 18″fluted ss and a 24″ ss for some varmint or long range matches. I’ll be sure to use Anderson lowers as well as other parts that fit my scope of build.
