Backup Tactical
American-Made Muzzle Accessories
Backup Tactical makes the muzzle-end hardware that finishes a build — CNC-machined thread protectors and drop-in threaded barrels, made in the USA and backed by a lifetime warranty on the protectors. At Keep Shooting we carry their full run of thread protectors — the American Flag, Frag, Hash, Honeycomb, and Revolver Cylinder designs — plus the drop-in Sig P320 threaded barrel. Functional gear that happens to look good at the business end.
About Backup Tactical
Backup Tactical is an American maker of CNC-machined muzzle accessories — the thread protectors and drop-in threaded barrels that finish a build at the business end. At Keep Shooting we carry seven of their SKUs, and you’ll find them all in our thread adapters and protectors category.
Thread Protectors
A thread protector does a simple job — it caps your exposed muzzle threads so carbon, grit, and corrosion can’t chew them up while no suppressor or muzzle device is mounted — and Backup Tactical does it with style and a lifetime warranty. For pistols and any 1/2x28 barrel, the 7075-aluminum caps come in four looks: the American Flag, the Frag, the Hash, and the Revolver Cylinder, each fitting 9mm and .22 LR threaded barrels. Rifle shooters get two more: the Honeycomb .223 Protector in 6061-T6 aluminum for 1/2x28 AR-15 muzzles, and the Hash .30-Cal Protector in 5/8x24 steel for .308 and 300 BLK. Match the thread pitch to your barrel and you’re done.
The P320 Threaded Barrel
Stepping up from accessories to a real upgrade, the P320 Full Size Threaded Barrel is a drop-in 1/2x28 barrel for the Sig P320 Full Size in 9mm. It’s machined from 416 stainless steel with a black nitride finish and pulled-broach rifling, it’s loaded-chamber- indicator compatible, and it ships with a thread protector in the box. That gives a stock P320 everything it needs to run a suppressor or a compensator — and once you’re mounting an NFA can, we handle the transfer as a licensed Class 3 dealer.
Pairing & Cross-References
Backup Tactical sits in our thread adapters category right next to the United Defense thread adapters — so if your pistol’s factory threads don’t match your can, you can adapt them and then cap them with a matching protector from one stop. Both are part of the broader gun parts catalog. New to threading a barrel or running a suppressor? Our thread adapter guide walks through pitch, fitment, and keeping your threads protected. Every Backup Tactical order ships from Keep Shooting with fast handling and our satisfaction guarantee.
