SIG TAPER-CAP-762 TAPER CAP 762BBL 5/8-24 THRD
$22.73
The SIG TAPER-CAP-762 is a taper cap designed for .762 barrels with 5/8-24 threading. This accessory serves as a protective end cap for rifles equipped with suppressors, muzzle devices, or threaded barrels where you need to cover the threads when running bare—whether you're between suppressor sessions, storing the rifle, or transitioning setups at the range. It's a straightforward solution for keeping your barrel threads clean and protected from debris and corrosion.
If you're running a suppressed rifle (or plan to), having a quality taper cap in your gear bag is practical insurance. SIG Sauer manufactures this cap to fit their own platform specifications, so compatibility with your specific barrel threading is the main consideration—but if you're building around a .762 barrel with 5/8-24 threads, this cap threads on securely and stays put. It's the kind of small accessory that doesn't get talked about much until you need it.
Built in black, it resists corrosion and blends visually with most rifle finishes. At its price point, it's an economical way to protect threaded barrels between shooting sessions or when your primary muzzle device is off the gun.

Frequently Asked Questions
Will this taper cap fit my SIG rifle?
The SIG TAPER-CAP-762 is designed for .762 barrels with 5/8-24 threading. Verify that your barrel has this exact thread pitch and diameter before ordering. SIG MCX and M400 platforms with this thread spec will be compatible, but double-check your rifle's barrel specifications to confirm.
What's the purpose of a taper cap?
A taper cap protects your threaded barrel when you're running without a suppressor, muzzle brake, or flash hider. It keeps threads clean, prevents corrosion, and seals the muzzle during storage or transport. It threads on and off like any muzzle device.
Can I use this with a suppressor installed?
No. The taper cap is for bare barrels or when your primary muzzle device is removed. If your suppressor or muzzle device is threaded onto the barrel, there's no room for the cap.
