i have a sportical, (impulse buy, $587.00 at wally world same basic thing, but slick side)

the gas block is secured to the barrel with set screws, the gas tube pin is straight, the barrel is .750 under the gas block.

i broke mine in with M855 ammo. and wolf polyformance 55gr FMJ, 300 rounds or so thru the thing as of now and not one issue.

the stock FCG isn't really that bad, a spring kit probably wouldn't hurt.

Yes on the M4 feedramps, and they are done correct.

gas key is staked properly, castle nut was not staked.
