Stainless steel body · 3× tungsten weights · AR-9 and 9mm PCC blowback compatible

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.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.
