Contrary to what some may believe, the AR-15 is not an automatic rifle. This means that it cannot be left to fire multiple rounds on its own until the ammunition runs out or the user makes it stop. The military-grade weapons that served as the type's basis are fully automatic, but their civilian counterparts lack that feature. With that said, they can be semi-automatic. You just need a 5.56, .223, or 7.62x39 bolt carrier group in stock — whichever one fits your own AR.

This part covers a good chunk of the rifle, with its most important connection being to the trigger. When the user pulls it, it does much more than ignite the powder and blast out the bullet. The firing pin can now make contact with the round's primer, the BCG chucks out the spent shell, the hammer gets pushed back into place, and the next round is lined up. All these actions occur practically between breaths, and the result is semi-automatic magic.

When you need top-of-the-line AR-15 bolt carrier groups, Gorilla Machining has your back. Other retailers provide low-quality hand-me-down products from other manufacturers. We make our own products, designed to meet exacting quality standards because we know our customers accept nothing less than the best. We always have 5.56, .223, and 7.62 bolt carrier groups in stock, so shop with us today and Improve your rifle right away.

The Best AR-15 6.5 Grendel Type 2 Bolt Carrier Group Black Nitride MPI

For gun fans looking for unmatched performance and dependability, the Gorilla Machining AR-15 6.5 Grendel Type 2 Bolt Carrier Group Black Nitride MPI is a standout option. The bolt carrier group (BCG) is designed with extreme care and accuracy, utilizing state-of-the-art materials and innovative production techniques to guarantee peak performance even under the most severe circumstances. We get into the details that make this BCG a standout part for your AR-15 platform down below.

Magnetic Particle Inspection (MPI) is performed on each Gorilla Machining BCG to guarantee structural integrity. MPI is a nondestructive testing technique that finds surface and subsurface metal faults like inclusions or fissures. Every BCG is guaranteed to satisfy the highest standards of quality and safety thanks to this stringent inspection procedure.

Because of the 6.5 Grendel cartridge's exceptional ballistic performance and adaptability, it has becoming increasingly popular. The 6.5 Grendel bullet is intended to increase the accuracy and range of the AR-15 platform. It has a flatter trajectory, less wind drift, and more retained energy than the 5.56 NATO cartridge. Reliable chambering and extraction are ensured by the Type 2 bolt's special engineering designed to fit the 6.5 Grendel cartridge's unusual size.

For any AR-15 platform chambered in 6.5 Grendel, the Gorilla Machining AR-15 6.5 Grendel Type 2 Bolt Carrier Group Black Nitride MPI is an excellent upgrade. This BCG offers unrivaled performance, durability, and dependability thanks to its careful craftsmanship, sophisticated materials, and strict quality control. Regardless of your interests—competitive shooting, hunting, or collecting firearms—this BCG is made to both meet and beyond your needs.
