he cut new feed cones in both my ar 9 barrels and sent him my friends for the same treatment. he called saying that because of the factory "feed ramp" he wasnt able to do it and instead offered a new macon armory barrel for free and he would keep the shitty delta team tactical (iirc) my buddy bought for his wall of shame. put the upper together last night and ill test it out later today.
big thanks again rudy
