I have been curious about this brand of BCG, but have not had the chance to check it out in the field yet. I'm hoping it performs as good as it looks.
MPN: BCG-M16 / BCG-AR15
**A full-auto (A.K.A. M16) bolt carrier installed in a standard semi-auto AR-15 will not make the gun fire full-auto.
Since a bolt carrier group (BCG) is critical for the overall performance of an AR15, you should always choose a brand with a reputation for excellence such as Phase 5 Tactical.
The Phase 5 Tactical Phosphate Bolt Carrier Group is designed to chamber and fire rounds with the utmost precision and uncompromising reliability. You can count on Phase 5 Tactical to machine each part to the most exact Mil-Spec tolerances. This BCG is heat-treated and undergoes full HPT/MPI testing.
An impermeable coating of black phosphate is applied to all of the parts. This type of coating is known for reducing friction, eliminating corrosion, and preventing wear. The black color of the coating is also great for those who are building a camouflage rifle; it is not as easily visible as a chrome or nickel plated carrier. An interior chrome lining on the carrier creates a naturally low-friction surface that repels fouling and corrosive elements.
Get your AR15 the very best - the black phosphate BCG from Phase 5 Tactical!
"The US Mil-Spec assembly drawing requires the carrier key to be staked. Contrary to some popular opinions staking does not “SEAL” the gas key. Staking only keeps the screws from backing out.
If you do not properly torque the screws to 56 inch pounds you will be staking a screw that is loose or one that is over torqued and prone to breakage. We have seen plenty of staked screws that are loose or broken."
**Phase 5 Tactical install the key and torque every screws to 56 inch pounds. Since the gas keys were not stake, you have the option to remove the gas key. (i.e. replace with a pistol key.) When you put the new key on, do not use the old screws, go buy new 10-32 x ¼" SHCS from you local hardware stores. If you use the old screws, you will most likely break them during installation or when you fire the rifle.
