    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 one of these lowers and registered it for an SBR build and couldn’t be happier. Quality is great and at a very reasonable price – no need to buy from anyone else! Customer service was a joy and the transaction to my FFL was a quick and easy process. No complaints here! Will buy again and highly recommend anyone do the same!

    In the pics the trigger and hammer appear to be different from the black parts seen in other lowers. Is this the same trigger as found in your other lowers or an upgrade? Thanks!

    I purchased this lower from Sportsmans Guide along with the combo uppers(5.56 and .300BLK). I have only had it out once and the gun functioned great until the trigger pivot pin walked out a little causing the trigger to tweak to one side a little. This is my first AR so it took me a minute to figure out what was going on. Overall, from my newb perspective, I am very pleased with it so far. I will keep an eye on things and see how it goes.

    • Michael Johnson

      please let us know how things go and if we need help in any way
