Reviews & Ratings for Cross Armory Quick Takedown Pins — 8 reviews — Page 1

I absolutely love this quick release system. So easy to open the receiver now. It was a bit of gunsmithing to install, though, but it was so worth it. It comes with shims if the pins are too far forward of the holes, but there are no instructions on what to do if the pins don't quite reach the holes. I used my barrel lapper and lapping compound to slowly remove material from the rear of the lower receiver. You have to put the upper receiver on so the lapping tool aligns correctly. After quite a bit of lapping, I was able to get the pins to align almost perfectly. I used a takedown pin tool and a small amount of a higher grit lapping compound to smooth out and align the quick release brack with the lower pin holes. If you have the patience, I highly recommend it. Just take your time and get it aligned right. Don't just slap it on tighten it down, and expect it to work perfectly. I ordered several more for my other AR-15's as well as 2 for my AR-10's.

not to bad to put. took a while to get the old pin out. of course put the wrong sides in the wrong place so had to disassemble again. Make sure you put the correct sides in otherwise the lock is flimsy and would probably pop open during firing!!

Have many of these on AR15's first for AR10! LOVE IT!!!

Clear instructions
Required a little bit more time than I expected due to having to install a shim, but NBD.
Will take some practice to get used to a little more bulk to get around for the safety selector.

Not a quick install, needs some fiddling to get the proper clearance but it comes with the shims you’ll need. Mine used the .15 shim. Yours might be different. Follow the instructions.

After following detailed instructions and shimming the buffer tube lock nut I was able to release the uppersatisfactory. Unfortunately thee effect of my lower tipping on its side (equating to maybe a 2" drop) the gun became unusable again. Yes, I did torque the nut.

though quite pricey, worked as advertised. got myself a king pin since i live in california but it did not work since the pin/spring of my AR15 (DRD-CDR15) is located at the bottom not the back. so if your AR has the pin/spring at the bottom, this is the only solution that works

These really make having a California Legal AR less of a hassel... with their Flop Stop you can open the gun drop the magazine and insert a new one very fast and effectively. I would highly recomend these....
