Modifies PAN and ACME breech caps (1111 and 4340) to work like the protective breech caps (1113 and 4341)

4 set screws clamp the protective ring to the breech cap

Protects the breech plug from being hit if the disrupter hits the ground

One ring works on both the ACME and PAN breech caps

Made of rust resistant, strong, and lightweight titanium

The plastic breech protector, 4346, works similarly by slipping over the breech cap and plug
