PNW Arms 300 BLK Upper + Ammo Combo

The modular design of the AR platform makes it one of the most versatile weapon systems available. By popping out two pins—the takedown pin and the pivot pin—a user can remove one upper receiver and swap it with another so a carbine used for home defense in 5.56mm NATO can be turned into a 300 Blackout or 6.8 SPC rifle to hunt whitetail deer.

If wild pigs are on the hunting agenda, then “thumper” calibers like the .458 SOCOM or the .450 Bushmaster are good options. Even low-cost plinking with a .22 LR upper can keep your shooting skills sharp while keeping costs at a minimum. AR-platform rifles allow users to get the upper hand in any situation. Here’s a look at upper receivers that range from plinkers and trainers to hunters and tactical options.

ADCOR Defense A-556 Elite

ADCOR Defense rifles and uppers use a gas piston operating system with a forward reversible/ambidextrous non-reciprocating charging handle. The gas-driven piston is built into the upper half of the forward rail system and does not touch the barrel so the barrel floats freely for increased accuracy. Barrels are available in 10.5-, 14.5-, 16.1- and 18-inch lengths, and each barrel has a 1-in-7-inch twist rate as well as a chrome-lined bore. A2-style flash suppressors are attached at the muzzle.

All of the BCM flattop uppers feature laser-etched “T” marks to make consistent remounting of sights and accessories easier. Standard uppers match or exceed GI specs, with a 1-in-7-inch twist, CMV-grade steel, chromed bore and chamber, standard profile and 5.56mm NATO chamber. Barrels are subjected to the M197 high-pressure test load, rated for 70,000 psi, and then undergo magnetic particle inspection to detect any possible flaws in the barrel’s surface.
