What's going on with all the 20" barrels, they all seem to be drying up.
While I prefer to use a BCM 20 inch barrel with 1 /7 twist, F marked front sight base and M4 feed ramps, their barrels have been sold out for some time. CMMG seems to no longer have them on their web site and Bushmaster's 20" government profile barrel with no 1/7 twist + no M4 feed ramps + no F marked front sight base = I'm not buying it for my A4 build.
What's going on here?
