  1. Been buying M4E1 Lowers for a few years & they’re very good! The lowers & uppers save time & money with the trigger guard forged with the lower, & the set screws for the bolt catch, forward assist, & take down spring/detent. I almost forgot how to install roll pins after using them for so long!!

  2. I have two of them also they are excellent. The mag well flare is done by a broaching machine and is seen only in the best lower AR receivers. Some not so good lower parts kits don’t fit so well as they have great machining. I just got their upper and the bolt carrier. They are great also.
