The AR-9 blowback platform is notorious for one problem: buffer weight. Unlike direct-impingement AR-15s, the 9mm blowback AR-9 has no gas system to regulate cycling — it runs entirely on bolt mass and spring tension. Get the buffer weight wrong and you get short-strokes, failures to feed, excessive recoil, or a rifle that beats itself to pieces. The Odin Works Adjustable 9mm Buffer solves this with 5 weights — 1 aluminum, 1 stainless steel, and 3 tungsten — covering a 5.4 to 7.4 oz range that handles everything from standard 115gr loads to +P ammunition and everything in between. 100% USA made in Southern Idaho.


5-Weight System — Tungsten Heavy

Built Heavy for 9mm Blowback

Unlike the AR-15 system, the 9mm buffer includes three tungsten weights — because the AR-9 blowback platform needs mass, not just versatility. Heavier is almost always better in a blowback AR-9. The three tungsten weights let you dial in the precise heaviness your specific 9mm build and ammunition require.

AL Aluminum × 1 Light end — minimum config at 5.4 oz
SS Stainless × 1 Mid — intermediate blowback tuning
W Tungsten × 3 Heavy — 3 tungsten for maximum 7.4 oz config
5.4 Min oz Lightest 9mm blowback config
7.4 Max oz Max weight — +P, heavy loads, suppressed
Why 9mm Blowback Needs a Heavy Buffer

In a direct-impingement AR-15, the gas system bleeds off energy before it reaches the BCG. In a 9mm blowback AR-9, there is no gas system — the bolt moves directly from cartridge pressure with nothing to slow it down except buffer weight and spring tension. This is why an AR-9 needs a much heavier buffer than an AR-15 running the same barrel length. Under-buffered 9mm blowback builds short-stroke, fail to eject, or run so harshly they damage components. The Odin Works 9mm adjustable system — with its three tungsten weights — gives you the mass range to dial in any 9mm blowback build running any ammunition.


Key Features

The 9mm Buffer Your AR-9 Deserves

  • Three tungsten weights included — the heaviest weight option available. Three tungsten weights give you fine-grained control over the heavy end of the 9mm blowback weight range where most AR-9s need to operate.
  • 5.4 to 7.4 oz range — the widest weight range available for 9mm blowback AR platforms. Covers light 115gr target loads through heavy 147gr subsonic and +P defensive ammunition.
  • Stainless steel body — heavy-duty construction matching the demands of the high-cycle-rate 9mm blowback operating environment. Built to outlast aluminum alternatives.
  • AR-9 and 9mm PCC compatible — fits standard AR-9 mil-spec buffer tube configurations used by Glock-pattern, Colt-pattern, and other common AR-9 lower platforms.
  • Suppressed 9mm optimization — running a suppressor on your AR-9? Start with maximum weight. The additional backpressure from a suppressor dramatically changes cycling behavior in blowback systems — the adjustable range gives you room to tune.
  • Competition 3-Gun PCC tuning — 9mm PCC is one of the fastest-growing competition divisions. Fine-tune your AR-9 for the specific ammunition and stage requirements you're running. Change configs between matches without buying new buffers.
  • Face-mounted set screw — swap weights from the front without disassembly. Field-adjustable in seconds.
  • 100% USA made — Odin Works, Southern Idaho. Lifetime warranty.

Don't waste your money!

Do NOT buy unless you like throwing away your money! This Ethical Pets 54093 Skinneeez Frog seemed like a great dog toy, but my Malti Poo destroyed it within TEN minutes! He actually ate the material and half of the squeaker before I found the other half. Guess we’ll be seeing that outside in a few days! This toy is listed as “Durable Dog Toy”, but it is NOT. I’ve got dog toys from the dollar store that lasted for months! We will not be buying nor recommending this product again. Don’t waste your money!

Great toy
Color: Grey
My girl loves this toy. She has a lot of toys but this is her favorite. She is a 26 lb mini golden and we have had it over a year. It is just now starting to show wear. Once it is completely worn out I will buy it again!

15 Minutes….with update x2
Color: Orange
Within 15 minutes my 10-month old puppy had one of the moose antlers torn half off. I’ll see if he is able to destruct any more of this “indestructible” toy. If it holds up I’ll come back and upgrade the number of stars but for now…not impressed. UPDATE: Sadly he was able to rip it open via the appendages (the legs). The main body of the toy seems pretty tough but no dog is going to keep away from the legs. Downgrade to 1 star. UPDATE #2: I just received my second attempt at using this “indestructible” toy. This time I went with the rino since the legs are rope and not a sewn on leg. Well, in about 5 minutes my puppy had the horn torn and the horn provides direct access to the inside stuffing. As mentioned above, the legs are rope. The design was pretty smart in that both the front legs is one posted of rope going through a hole made in the stuffed toy. Same for the rear legs. This prevents the dog tearing them off and getting access to the stuffing. Sadly the horn being torn off right away makes this toy destructible. I think the only way they may be successful calling this an indestructible toy would be if they made a ball out of the body material or perhaps something in the shape of a bone.

AWESOME TOY for aggressive chewers
My 4 legged fur baby has only had for a few days. Now we’ve purchased several others in the past and he LOVES them. EXTREMELY durable. He is a dachshund and loves to destroy his toys. It’s almost like it’s a mission to see how fast to get the stuffing and squeakers out of his toys and can say he has been unable to destroy any. Now the reason I gave this only 4 stars is because the end of the tail has hair like material and he did start tearing this apart. Was finding the hair on his blanket and hanging out of his mouth. So I just trimmed the tail and he is back to loving on his toy. I would highly recommend this to anyone.
