Stripped a bolt? Lost the thumbscrew? Picked up a used EOTech with rough or missing mounting parts? This is the kit that sets things right. It replaces the small but critical pieces that hold your holographic sight to the gun, and it's built by EOTech to match the original factory hardware so you're not left guessing on fitment.
This kit is made specifically for the 511, 512, 551, and 552 holographic weapon sights. Inside you get the knurled Weaver-style mount bolt, the socket head (Allen) cross-bolt, a plastic retaining washer, the Weaver lock bar, and a 7/64-inch Allen wrench so you have the exact tool for the job. The steel components are precision machined, which is what keeps your sight locked down and holding zero once it's torqued in place.
Installation is straightforward and doesn't call for any specialized gunsmithing tools. The mount clamps to a standard Weaver or Picatinny base, and the knurled thumbscrew lets you snug things up by hand before you set it with the wrench. Folks who've grabbed one to fix up an older or secondhand sight consistently mention that it brings the mount right back to how it left the factory.
These are the parts that tend to wander off or get over-tightened over the years, and they're not something you'll find at the local hardware store. Keeping a spare kit in the range bag or on the bench means a stripped washer or a missing bolt won't take your EOTech out of the fight. It's a small piece of insurance for a sight you rely on.
It's designed for the EOTech 511, 512, 551, and 552 holographic weapon sights. It does not fit the XPS or EXPS series, which use different mounts. If you have one of the four listed models, this is the correct factory replacement hardware.
You get the knurled Weaver mount bolt, the Allen head cross-bolt, a Weaver lock bar, a plastic retaining washer, and a 7/64-inch Allen wrench. That covers the full set of small parts that clamp the sight to your rail. Having the correct wrench included means you can install it right out of the package.
No. The kit ships with the 7/64-inch Allen wrench you need, and the knurled thumbscrew lets you hand-tighten before final snugging. It mounts to a standard Weaver or Picatinny rail without a trip to the gunsmith.
Yes, that's one of the most common reasons people grab this kit. It replaces stripped, over-tightened, or missing mounting parts and brings a secondhand sight back to factory condition. It's also a good spare to keep on hand since these pieces aren't sold at typical hardware stores.
