Ok guys haven’t posted in here for awhile. Need help decided on caliber. These are my short to mid range with bolt action preferred for my long range but I am considering either the .556, .224 Valkyrie, 6mm ARC or the 6.5 Grendal! What’s your thoughts? I’m really interested in the 6mm ARC but not much available in the brass dept! As of these left to right is my currently waiting a form1 stamp .300blk Spikes receivers Samson tube and Wilson Combat 11.3” barrel with a dead air break, next is my 5.56/.22 again Spikes receivers adams piston, Binary Trigger Samson tube and a Noveske 13.7 pinned and welded with a dead air break. Next is my Custom built by Allen Moore AK-47 with a 14.5” pinned and welded Crome lined barrel, FA Binary Trigger added adjustable gas piston law side folder and probably my favorite one to shoot.
