“As expected of Aero Precision, the lower is great! Something to note, the buffer tube is commercial and not mil-spec. Fit my upper assembly perfectly and I have had no issues with function. I did make one change as soon as it came in. I replaced the safety selector with a radian talon ambi selector. It dropped in perfectly with no effort and I haven't looked back!”
“Been looking without much luck recently for an M4E1 lower to start another build. Found a complete lower minus stock through these guys. Couldn't be happier. Nice finish, machined nicely and functions like a champ. DANG !!! As usual, should've grabbed an extra. It's the start of a new pistol setup.”
