The Odin Works 9mm Buffer seems to work well as expected in my Freedom Ordnance FX9 project so far.
With that and the Midwest Industries muzzle brake, the platform shoots very flat and throws brass at a consistent range of 4 - 5 O’clock at a good distance.
Next up will be to experiment with a bit heavier buffer spring to see just how tuned it can get.

Makes it easy to dial in proper bolt carrier speed and operation of AR9. Love these and have multiple for all 3 platforms. AR9, AR15, & AR10. Definitely a solid purchase for optimizing your weapon.

I use the ODIN 9mm adjustable buffer to tune my builds to the load used. I have 9mm's with barrels from 5 inches to 18 inches. Some are for subsonic loads, some are for reduced loads, and some are for full power loads. They are supplied with many weights included to handle most situations. With the ODIN all are tuned to the proper recoil resistance. They also work great in other type AR's.

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.

If you do multiple builds with multiple calibers across deferent platforms, this is an essential item. Tuning rifles from 9mm to 300wsm utilizing carbine and a5 buffer tube combinations this is what you need to get the cycling and recoil impulse perfect for your project. This thing is built like an up armored tank and optics planet had the best price anywhere.

I use this Odinworks adjustable buffer on an ar9 PCC I've been building.. if you're familiar with ar9 BCGs then you'll know some of them have a weight pinned in at the rear of the bolt.. and if you want to put a folding adapter (i used the law tactical) then you'll need to un-pin that weight, therefore losing some of the reciprocating mass.. Other reviews have mentioned the 23 grams minimum total weight for BCG and Buffer, I'm here to mention this WILL help get back to that magic number if you have to remove the Bolt weight for a Law Tactical folder. My PCC now cycles and feeds reliably AND has a good cyclic rate for those times you may want to be super safe about things ...
I also recommend a little thread lock for all the set screws (once you have your preferred weight adjustments tuned in)
Would recommend: Yes

Looks like good quality. I love the fact weights can changed and don’t have to buy multiple buffers to find out what works best.
