AR-9 Standard 9mm BCG (Glock, Colt, and MP5 Compatible)

  • US Made 8620 steel with nitride finish
  • Ramped carrier to work with both 9mm and standard AR hammers
  • Precision milled for use with Glock style, MP5 Style or traditional Colt style AR-9 lower receivers
  • M-16 cut for use in transferable full auto MG's, dealer post sample MG's or other legal machine guns (ALL BATFE RULES APPLY)

**NOTE: Many Aftermarket drop in triggers use modified hammers which may not reset properly, or hit the firing pin square on the carrier which could cause firing pins to bind and snap. We recommend using only MILSPEC hammers with any 9mm, .40, or .45 blowback bolt carrier groups.

**A small amount of Loctite is recommended on the set screw that holds the BCG weight in place. 

**NOTE: This BCG will not work if used in a standard 5.56 upper receiver with dust cover

The New Frontier Armory AR-9 9mm Bolt Carrier Group is proudly MADE IN THE USA by hard-working American men and women.

    9mm BCG

    Posted by Ray F. on 16th May 2024

    I built an AR platform, utilizing MP5 magazines. The BCG I originally had, could not be used with the magazines. I chose the NFA BCG and solved the feed problem.

    The best AR -9 BCG out there.

    Posted by Connor from Gun Guys on 1st May 2024

    The N F A 9mm BCGs are my go-to favorites. Reliable, built to last and weighted just right to cycle smoothly. That and the fact they run on various types of lowers makes it pretty easy to just grab the new frontier BCG knowing it’s going to work.

    CustomIzation

    Would it be possible to get an MP5 magazine compatible 9mm BCG that had a right side charging handle in order to make a right side charging AND right side ejecting upper for my C5 lower? I’d be happy to pay a little extra

    I put together a New Frontier Armory C5(MP5) AR9 earlier this year and chose this bolt carrier for the project. Its been several months since I completed the build and I can say I am very happy with this BCG and the new frontier upper and lower I used as well. I have literally had 0 issues with the gun since completing it and it is a ton of fun to shoot. I did unfortunately run into one big problem with the gun recently and that is the way 9mm ammo prices have skyrocketed in the last few months but if you are looking for a BCG for a MP5 mag compatible lower I would 100% say this is the BCG you need. Ive seen more than a couple people get MP5 mag lowers and all have issues because they try to use standard AR9 BCG's. Save yourself a headache and get the correct BCG the first time
