This Magazine adapter fit perfectly. Tried it in an older and newer PSA AR-15 mag well as well as my Aero lower. All of which fit perfectly. The Aero was a little more snug than the PSAs but I had no issues with the fit and function of the 15, 17, and 21 round P320 mags that I have. All Sig made mags. I’d assume they’d work with the cheaper mags as well.
Worked for both my AR15 and AR10 builds. Perfect for use on barrel nuts on both builds. Definitely a must for anyone building their own AR platform riffle/pistol. I was also able to use this to torque the barrel, tighten my muzzle devices and crack open a longneck at the end of the day. Cheers!
Fit and finish on these sights are perfect on my Trybe slide. They’re what you’d expect from Trijicon. Easy pickup of sight picture in the day and very bright at night. They’re a perfect match to add to a later upgrade on a RMR.
