Quality product, works flawlessly by KB, November 6, 2019
This product works 100% with my echo trigger and my sylvan arms folding stock adapter. The NiB finish is a must for a dirty suppressed 9mm blowback. I couldn't recommend this product enough. I wasted money on other 9mm carriers before getting this on...
