Description
If you run a .308 AR and deal with gas hitting your face every time the bolt cycles, the Breek Arms Sledgehammer was built to fix exactly that. This is the AR-10 / LR-308 version of Breek's popular gas-blocking design, and it packs in more gas mitigation than just about anything else in its class. The whole thing is CNC machined from 7075-T6 aluminum and wears a Type III hard-coat anodized finish in gray, so it holds up to hard use and stays looking sharp.
What Makes the Sledgehammer Different
Gas control is the whole point here. The Sledgehammer uses a higher raised shelf at the rear of the upper to block blowback, an innovative keyway cutout that stops gas from creeping over that shelf, internal baffling inside the stem to slow expanding gas, and a back pressure port with relief cuts on the top and bottom that steer gases sideways. Stack all that together and you get a noticeably cleaner shooting experience, which is why folks running suppressors gravitate to it. Even on a plain overgassed rifle it takes the edge off.
Built for Real-World Manipulation
The dual ambidextrous latches are serrated for a solid grip, and the wider footprint gives you plenty to grab whether you're left-handed, right-handed, or wearing gloves. At just 1.4 ounces with a 2.59 inch latch width, it won't weigh down your build or feel bulky under a large optic. Charging feels smooth and secure, with latches that stay put when you need them to.
Fitment for Your AR-10 Build
The Sledgehammer is designed for DPMS-style AR-10 and LR-308 platforms and installs with no gunsmithing required. It covers a wide range of uppers including Aero M5, DPMS Gen1, Knights Armament SR25, Armalite AR10, Daniel Defense DD5, plus DPMS Gen2 pattern rifles like the SIG716, Ruger SFAR, Savage MSR10, and S&W M&P10. Check your specific upper against Breek's compatibility list before ordering, and note that this handle is proudly made in America.

Frequently Asked Questions
Will the Sledgehammer AR-10 charging handle fit my rifle?
It's built for DPMS-style AR-10 and LR-308 uppers and covers a lot of ground, including Aero M5, DPMS Gen1 high and low, Knights Armament SR25, Armalite AR10, and Daniel Defense DD5. It also fits DPMS Gen2 pattern uppers such as the SIG716, Ruger SFAR, Savage MSR10, and S&W M&P10. Since .308 platforms vary more than AR-15s, it's worth matching your specific upper to Breek's compatibility list before you order.
Does the Sledgehammer really help with gas blowback?
That's the main reason people buy it. It combines a raised rear shelf, a keyway cutout, internal baffling in the stem, and relief cuts to steer gas away from your face rather than into it. It's especially noticeable on suppressed rifles, though it also helps tame an overgassed setup.
Is this charging handle truly ambidextrous?
Yes. Both latches are functional and serrated, so you can charge the rifle from either side with equal ease. The wider footprint gives you a solid grip whether you're left-handed, right-handed, or running gloves.
Do I need any tools or gunsmithing to install it?
No gunsmithing required. It's a straight drop-in swap for your factory charging handle, so you can pull the old one and slide this in without any special tools. Most builders have it done in a couple of minutes.
