Will this work for angstad ar9 ?

Bought one and used 7.4 weight for a total weight of 21 ounces ( bolt+ buffer) on my angstad ar9. Functioning smoothly and softer recoil. Just follow the instructions on how to assemble the buffer. Highly recommended.

How long is the buffer? Is it 4"? Expert Answer

The ODIN Works 9mm Adjustable Buffer is a carbine length buffer. However, Odin Works does not specify the actual length of the ODIN Works 9mm Adjustable Buffer. I recommend contacting Odin Works for that information.

It's a standard carbine length so you'll need to compensate somehow for the shorter length. They should really make it 4" long like it should be for use in an AR9.

Best Heavyweight Buffer for AR10 with A5 Buffer Tube by Seb, Verified Owner, July 31, 2025
This worked perfectly in my PSA Gen3 PA10 with an RE-AT Vltor tube to tune it to perfection. Just make sure to loctite the screws once you set it up the way you want it! They will back out on you while shooting eventually.

Helps dial in AR9's by Slick Daddy, Verified Owner, January 10, 2024
If youve ever built an AR9 from ground up youll find out, or maybe you already have found out, they can be very finicky. One area where they can be finicky is proper carrier/buffer weight combo. Experts that have built many AR9's in the past have re...
