The Toxic Arms (MPI) complete bolt carrier group is fully assembled and made in the U.S.A.. This bolt carrier group is full auto rated making it more than strong enough for your semi auto AR15. An upgraded Nitride exterior and inside is used for added durability and scratch resistance. The surface hardness is HR15N 89.5 ~ 91 which can be a full 20 point better than other competitors. Machined to USGI specifications. This M15/M16/M4 carrier includes the proper Mil-Spec gas key. Gas key is Nitride coated and heat treated.

We only use Chrome Plated firing pins. Chrome firing pins are stronger and easier to clean than standard firing pins.

We feel the bolt carrier group is one of the most important parts that is in any AR style rifle. Toxic Arms has the high-end BCG every AR15 user should have at a reasonable cost to the end user.
