Updated design of the standard AR-15 bolt features a fully supported breech face and a dual-spring extractor system for extra strength and reliability to handle the 6.8 Remington SPC II or 224 Valkyrie cartridge. Machined from an extremely hard steel alloy normally used in high-stress/heat applications like race car transmissions, then shot-peened and x-rayed for flaws before plating with a nickel-boron (NiB) coating. NiB coating significantly reduces friction coefficient, so the bolt is less likely to be hung up by fouling, and wear-resistance is greatly enhanced. Super-slick surface makes cleanup easy because carbon and gunk have a hard time sticking to it.
SPECS: Ultra-hard steel alloy, nickel-boron plated, silver finish. Comes complete with ejector, extractor, and gas rings installed. Fits a standard AR-15 carrier.
The MAGPUL PMAG GEN M3 polymer magazine continues to revolutionize magazine technology for the AR-15 / M4 platforms. The third-generation PMAG further expands the strength, reliability, and versatility of the original PMAG.
The MAGPUL PMAG GEN M3 is molded from a polymer formula that delivers distinctly greater resistance to crushing and all forms of impact, with extra reinforcement in the mag catch and feed lip areas.
The MAGPUL PMAG GEN M3 features pen dot matrix on each side providing consistent ID marking that resists handling wear. PMAG 30 is available with plain, solid sides.
SPECS: Impact/crush-resistant molded hard polymer, Black or Coyote Tan. Compatible with AR-15/M4/M16, HK® 416, MR556A1, M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and other similar lowers. 5.56mm/.223 ammunition only.
