I have an Anderson Rifle M4 that I am using for 3 gun. Only upgrades from the base model is Hiperfire 24C trigger, BAD Charghing handle latch, Michulek Muzzle Break, and Midwest Industries Handguard. This gun will shoot SUB MOA groups at 100 & 200 yards. I think I would like to upgrade to a low mass BCG, and assume I need an adjustable gas block. My rig appears to be a carbine length gas system.
A couple of options.
1 Upgrade Gas System in current upper.
2 build a mid/rifle length upper for 3 gun
From what I have seen it appears the Rifle Length will provide the softest shooting. My goal is to minimize recoil for double taps on close and dirty stages.
I shoot 77 gr for long range, and 55 gr for 100 yard and closer
Thanks for your comments/suggestions
