AO Precision Premium Mil-Spec Phosphate Bolt Carrier Group - 158 HPT/MPI BCG

These Military surplus 158 Bolt carrier groups are manufactured by AO Precision to the exacting standards of the US Military. AO makes these HPT / MPI BCG's for other Military contractor juggernauts, such as FN America. All bolts are rigorously inspected and are individually High Pressure Tested and then go through a Magnetic Particle Inspection.


Mil Spec Bolt
  • 158 Carpenter Steel
  • Shot Peened
  • High Pressure Tested (HPT)
  • Magnetic Particle Inspected (MPI)


Mil Spec Carrier
  • 8620 Aircraft Grade Steel
  • Full Mass M-16


Mil Spec Extractor
  • 4140 Steel per ASTM A108, cold drawn and stress relieved BHN 187-22
  • Phosphate Finish
  • Extractor Spring
  • Black Extractor Insert
  • Viton O-Ring

Mil Spec Gas Key
  • 4130 Profile Extruded Steel
  • Grade 8 Hardware
  • Properly Staked
  • Chrome Interior

Please note: These BCG's are considered premium because of the materials used and the Military Spec requirements that are adhered to during the manufacturing process. The HPT/metallurgy equipment and processes that these go through are very hard to find and very expensive. These are battle proven (literally), but they may not be as pretty as other BCG's out there.

5 of 5 Right Place November 19, 2019
Reviewer: JustMe from Mont Belvieu, TX United States  
Right To Bear has never failed me nor any product purchased through this veteran owned establishment. The AO carrier group arrived in due hast (on time), as advertised, and as expected. Have not ran the item (a shame I know, been busy) but expect functionality to be a none issue and performance as product specifications have noted. Will continue to come back RTB for the products and the sales are always right on the mark. Thanks RTB!

5 of 5 Best Deal I've seen November 15, 2019
Reviewer: Rich from Woodbridge, VA United States  
I'm currently using 3-4 of these Bolt Carrier Groups in my guns. Maybe 1300 rounds combined, no issue thus far. The specs look too good to be true for the price, individual HPT and MPI, carp 158 bolt, etc. The ones I've received have been properly staked, minus one key on the second one I purchased (was staked, just not enough to my liking). The markings on the bolt look exactly the same as my circa 2015 BCM bolt, and AO provides bolts and carriers to many of the biggest names in the industry.

5 of 5 For duty use November 13, 2019
Reviewer: Clayton Hackbarth from Princeton, MN United States  
Not pretty, not ugly, just a genuine m4 replacement bolt carrier group at a great price. I will continue to purchase the bolt as long as they are available.
