The A*B Arms™ Mission Critical Kit™ is a collection of critical replacement parts for you and your AR-15/M-4 that are there to serve you in your time of need. The MCK™ is manufactured for military and law enforcement, as well as civilian firearms enthusiasts. The MCK™ will make sure you have what you need, when you need it.

The Mission Critical Kit™ includes the following items:

* One A*B Arms™ Chrome Firing Pin: The A*B Arms™ chrome plated firing pin is used as a replacement for the bent or flattened firing pin tips.

* One A*B Arms™ Nickel Boron Coated Cam Pin: The A*B Arms A*B Pro Cam Pins are built to Mil-Spec dimensions. The Nickel Boron coated Cam Pin needs virtually no lube during use.

* One A*B Arms™ Ejector and Ejector Spring: The ejector and spring fits all Mil-Spec AR-15 style bolts. Made out of S7 steel, shot peened and heat treated.

* One Ejector Pin: The ejector pin gives your ejector an excellent fit with your bolt assembly.

* One A*B Arms™ Extractor with Attached Extractor Spring: Always good to have an A*B Arms™, Swiss machined extractor available when your existing extractor tooth breaks.

* One Extractor Spring With Insert: Extra extractor spring with rubber insert, just in case.

* One Firing Pin Retaining Pin: These are usually lost or damaged when replacing your bolt or by prying and pounding on it.

* One Extractor Axle: Replacement extractor axle in case it’s lost while cleaning your bolt.

* Three Gas Rings: Existing gas rings are usually bent or broken by slamming the bolt into the carrier when re-assembling the bolt group.

* Two Vials of 3ml Breakthrough™ Battle Born High-Purity Oil: We’ve included two convenient spray vials of this synthetic, non-toxic gun oil. Great for areas where friction and wear are expected.

* One Tactical Black, Ballistic Nylon Case with Multiple Gear Pockets: This 5”x 3.5”x 1” compact zippered pouch is an EDC style kit that’s small enough to fit into your pocket or gun bag.

Reviewer: Bill Johnson from Arizona  
It's somewhat of a stress reliever to know you have you have a backup plan just in case. The little MCK will fit in my range bag or field pack. It's a nice selection of parts. I might add a couple items to mine, but there nothing I'd remove. Thanks for the backup!
