Ratings & Reviews
Upper rear takedown mount will not allow takedown pin to push through.
by ROBERT -
Upper appears to be of good quality. However, rear takedown mount will not allow pin to push through. I have two Pistol lowers and four regular lowers of different brands including FNL, Colt, Radical Firearms, etc. This upper will not allow rear takedown pin from any lower to push through. The hole will have to be milled out for it to work.

Ran seemlessly with PMC bronze 55 grain FMJ and with IMI SS109 62 grain. Consistently ejects at 1 o’clock and no issues or malfunctions.
Everything was as expected. I took a star off because it didnt fit in my lower the way it should. I had to take a mill fill and remove some material so the rear takedown pin would catch into the upper. To be fair my lower isnt a bear creek lower and this can be a problem when your matching a different brand lower to a different brand upper.
