Tacfire Mar010-750Gb Pin Rfl 750 Gas Block Comb$18.29
Availability: In Stock
The TacFire MAR009-750GB is a pinned and staked .750 gas block combination designed for AR-15 builds and mid-length gas system configurations. This is a straightforward, no-frills component for builders who need a reliable gas block that locks solidly in place. If you're assembling an AR from the ground up or replacing a worn gas block on an existing rifle, a pinned and staked setup eliminates wobble and keeps your gas tube aligned where it needs to be.
Pinned and staked gas blocks have become the standard in quality AR builds for good reason: the pin and stake method is proven, affordable, and doesn't rely on set screws that can loosen over time or fail under recoil. This TacFire unit brings that reliability to builders on a budget. The .750 diameter fits standard rifle-length and mid-length gas systems, making it compatible with a wide range of barrels and configurations. Installation requires drilling and pinning the block to your barrel, which most builders either do themselves or have handled by a gunsmith.
TacFire makes solid milspec-adjacent parts for the AR platform without the premium price tag. This gas block is a good choice if you're building a do-it-yourself AR, upgrading an existing rifle's gas system, or restocking a gunsmith's parts bin. Pair it with your choice of gas tube, bolt carrier group, and upper receiver to dial in your ideal configuration.
| Brand | TacFire |
| Model | MAR009-750GB |
| Type | Gas Block (Pinned & Staked) |
| Diameter | .750" |
| Platform | AR-15 |
The .750 diameter is standard for most AR-15 barrels with rifle-length or mid-length gas systems. Verify your barrel's gas block journal diameter (the section the block clamps around) before ordering. If your barrel is .625 or has an uncommon profile, you'll need a different size block.
A pinned and staked gas block is mechanically locked to the barrel and won't loosen or shift over hundreds of rounds of shooting. Set-screw blocks are easier to install but can creep loose if not maintained. Pinned/staked is the more permanent, reliable solution.
Installing a pinned and staked gas block requires drilling through the barrel and block, then driving and staking a roll pin. Many builders send this work to a gunsmith to ensure proper alignment. If you have the tools and experience, you can do it yourself, but a professional installation is often the safer choice.
