Bootleg Four Position Adjustable AR-15 Carrier - Complete Black Finish (BP-C15-D)

The Bootleg Four Position Adjustable AR-15 Carrier is a complete bolt carrier group built for shooters running suppressors or tuning their gas system for specific loads. Machined from S7 Tool Steel and coated with Lithium Isonite finish, this carrier features a four-setting adjustable vent system that lets you dial in the amount of gas cycling back into the action—a real advantage when you're chasing cleaner operation and less shooter fatigue, whether you're suppressed or running standard ammunition.

The adjustable vent design works by relieving excess gas pressure, which extends dwell time and reduces blowback. Best of all, you can turn the gas adjustment while the carrier is installed in your rifle, so tuning doesn't mean field-stripping and guessing. The carrier is fully MIL-SPEC compatible, uses standard AR-15 components, and ships with a staked MIL-SPEC gas key. It's rated for full-auto use, which means it's built to handle everything a semi-auto shooter can throw at it.

Whether you're running a can, experimenting with underbore barrels, or just want more control over your AR's cycling characteristics, this is a no-compromise way to get there. Drop it into any standard AR-15 lower and get to work.
