LRB M14 SA, Criterion Med Wt CL Barrel, all GI parts with basic upgrades.
So we all have a “truck gun” that generally is a beater we slap together to put a lot of rounds through and toss in the back of the pickup. I finally got done with mine, as my Colt and KAC are too pricey to drag around and beat up. Had enough spare parts to slap this one together; complete VLTOR lower with B5 Sopmod and RRA 2-stage, a 16” FN barrel on an Aero upper and a used DDM4 rail from my buddy. The only additions required were a full NBC BCG, BCM charging handle, MI combat sights, and a YHM QD muzzle break for the resonator. I am hoping mid-length gas with an H2 buffer should run reliably, can or no can. Not the greatest, but should be a decent beater.
