Anyone who has built or worked on an AR-15 knows the pain of a tiny detent spring pinging off into the carpet, never to be seen again. The LANTAC M-SPEC Field Repair Kit is built for exactly that headache. It bundles the little parts and fasteners that go missing or wear out most often, so you can finish a build, fix a rattle, or get a rifle back up and running without a parts-store run.
Everything in the kit is manufactured to LANTAC's M-SPEC standard, using correct materials, heat treatments, and finishes made to meet current military specifications. That matters with parts this small. A soft detent or a weak spring is the kind of thing that causes intermittent issues down the road, and quality doubling up on the pieces you're most likely to lose gives you a spare on hand.
The set leans toward the parts that see the most action and the most frustration. You get bolt catch components including a plunger, plunger spring, and roll pin, plus a 6-32 bolt catch set screw that plays nice with LANTAC, Aero, and other lowers. There's a 1/16th Allen key head to drive that set screw, and doubled-up buffer retainers and springs, takedown and pivot pin detents with their springs, trigger pins, and safety selector detents and springs.
This is one of those things that earns its spot in a toolbox or range bag well before you ever need it. Whether you're assembling a fresh lower, chasing down a loose bolt catch, or just want backups for the parts that vanish under the bench, having them in one place saves time and aggravation. LANTAC builds it in the USA and stands behind it with a lifetime warranty, so it's a low-fuss addition to any AR-15 owner's kit.
It comes with the small parts that go missing or wear out most on an AR-15. You get bolt catch components (plunger, spring, roll pin, and 6-32 set screw), a 1/16th Allen key head, plus doubled-up buffer retainers and springs, takedown and pivot pin detents and springs, trigger pins, and safety selector detents and springs. Most of the detents and springs come as pairs so you have a spare.
Yes. The 6-32 bolt catch set screw is made to work with LANTAC lowers as well as Aero and other common AR-15 lowers. If your lower is set up for a bolt catch set screw rather than a roll pin, this piece is a handy fit.
It covers a lot of the springs, detents, and pins you'd install during assembly, so it's useful during a build and afterward for repairs. Keep in mind it's a small-parts and fastener kit rather than a complete lower parts kit, so it won't include larger components like a trigger group or safety selector lever. Think of it as the backup and consumables side of your build.
LANTAC manufactures this kit in the USA to their M-SPEC standard, using correct materials, heat treatments, and finishes intended to meet current military specifications. It's also backed by a lifetime warranty, which is reassuring for parts this small and this easy to misplace.
