Hey There, * I am not in any way connected to our new supporting vendor, ICE ARMS. Recently I purchased an ICE ARMS Nickel Boron Bolt Carrier Group for $160 with free shipping: ICE Arms EXO NiB .223/5.56 AR/M16 Bolt Carrier Group Here's my take: 1. Affordable price, especially given Nickel Boron! 2. Built with the feel of strength and quality, compared to other BCG's I've owned. 3. Top quality metals used - see specs. 4. Cleans super easy. 5. Lifetime warranty with outstanding and friendly customer service. 6. Local new company with many new innovative goodies for your AR. Check their website: Ice Arms Specs: Ice Arms manufactured M16 BCG w/ Nickel Boron EXO finish. This is the same company that does the finish for Fail Zero BCGs. Nickel Boron has proven itself to be the most durable finish on the market. It’s much smoother than Hard Chrome, it’s easier to clean, makes the rifle cycle smoother, it can be run almost lube free for thousands of rounds. - 8620 Carrier - 9310 MPI HPT Shot Peened Bolt - Investment Cast Extractor - Properly Staked Key - Grade 8 Hardened Fasteners - EXO Nickel Boron Finish Blue Skies!
