Odin Works Adjustable AR-15 Heavy Buffer System — 7 Weights · Built for Forced Reset Triggers

CURRENTLY THESE ARE ON BACK ORDER FOR A BIT WHILE ODIN WORKS GETS THEIR MANUFACTURING CAUGHT UP. OUR ORDERS SHOULD BE RECIEVED AND FULLFILLED IN JUNE

If you're running a forced reset trigger or a Super Safety selector system on your AR-15, your buffer weight isn't optional — it's the difference between a rifle that cycles clean every time and one that short-strokes, fails to reset, or beats itself apart. The Odin Works Adjustable AR-15 Heavy Buffer System gives you seven tungsten carbide weights and the ability to dial in the exact buffer weight your build demands. One buffer. Seven configurations. 100% American made in Southern Idaho.

7 Adjustable Carbide Weights

• ◆Seven tungsten carbide weights — the heaviest, most durable weight material available for AR-15 buffer systems. Carbide outlasts steel and bismuth on every metric.
• ◆Full adjustability — configure your buffer from light competition weight all the way to heavy FRT-optimized weight. Every combination is field-adjustable without tools.
• ◆Purpose-built for forced reset triggers — engineered with the Disruptor FRT, ARC-Fire V2, and all other AR-15 FRT platforms in mind. Dial to H2 or H3 equivalent with precision.
• ◆Super Safety compatible — the Hoffman Tactical Super Safety selector system is the most buffer-sensitive forced reset system on the market. The Odin Works adjustable system eliminates buffer as a variable entirely.
• ◆100% American made — manufactured by Odin Works in Southern Idaho. Not assembled overseas. Not a rebrand. Built in the USA by one of the most respected AR-15 component manufacturers in the country.
• ◆Mil-spec carbine buffer tube compatible — fits any standard mil-spec AR-15 lower. No modification required. Drop-in installation.
• ◆Recoil management — heavier buffer weight also means measurably reduced felt recoil and muzzle rise, giving you faster follow-up shots on top of reliable FRT function.

Dial Your Exact Weight

Add or remove carbide weights to hit the exact buffer weight your build requires. Each weight configuration changes the cycling characteristics of your AR-15 — lighter for competition and standard semi-auto, heavier for forced reset triggers and Super Safeties.

Setting Up Your FRT Build

• 01Start heavier, tune down. When dialing in a forced reset trigger for the first time, begin with all 7 weights installed. Run 50 rounds. If cycling feels sluggish or the bolt doesn't fully return, remove one weight and repeat. Most FRT builds settle at positions 5–6.
• 02Gas system matters. Overgassed rifles can run lighter. Undergassed rifles need more weight. The adjustable system lets you compensate for both without swapping buffers.
• 03Suppressor users start at 7. Adding a suppressor significantly increases backpressure and bolt velocity. Start at full weight and tune from there.
• 04Super Safety users — position 6 first. The Super Safety selector system is highly buffer-sensitive. The cam timing that drives the selector's forced reset function depends on consistent BCG dwell time. Position 6 is the recommended starting point for most Super Safety builds.
• 05M16 BCG required for all FRTs. The adjustable buffer solves the weight side of the equation — you still need an M16-profile bolt carrier group for any forced reset trigger to function. If you don't have one, see the Disruptor FRT + BCG bundle.
