Unreliable FTF Issues

by hammysaggar, from CT, United States Written on January 4, 2020
.45 is a tough caliber in this format and this upper has consistently had multiple failures to feed and failure to stop open. Side charging is cool for running suppressed but this system is unreliable and even after sending back to FM it is still exhibiting the same issues. 10rnd Glock mags swell which may contribute to the issue but I'm not being paid to do their RnD. Just know what you are getting in for. I love the concept if it were only reliable.
Pros:
  • None
Cons:
  • Not reliable
Best Used for:
  • plinking
Would recommend: No
