CMMG, do you carry a 16" Pre-Ban M-4 barrel A-3 style upper? Also wanting it with a chrome lined barrel, bolt/carrier/charging handle and and the newer A-2 flash hider with no bottom slots. If you have this, can you shoot me a quote?
Can you detail the difference between the 1/9 twist from the 1/7? Not sure the difference in the two or which is better for all around use. I know the 1/7 can use higher grained ammo but what does that accomplish?
