“Very light block. Easy install. Put it on faxon gunners barrel and it cycles fine with all super/sub 300aac ammo that I've ran so far.
Very happy with Arm or Ally...Fast delivery. Thanks”
We're sorry to hear your item isn't fitting. It sounds like the tolerances of each of the items are very tight. You can either contact FAXON or us to facilitate an exchange. If you are interested in DIY methods, you could try to place the barrel into the freezer for a few hours, then, use a hair-dryer on high to heat the gas block before installation.
