I'm looking to build my first AR pistol in 300blk and am seeing that the ideal barrel length is 9" - that little is gained by stretching longer while less would let the bullet leave before all of the powder is combusted.
My question is, what happens if one were to use, say, a 5" barrel and a 4" suppressor...would this, ballistically, be nearly identical to a 9" barrel?
Please feel free to answer that question, correct any wrong assumptions I have, and/or offer any 300blk/AR Pistol advice you care to share. Thanks!
