UPBOLT Anti-Jammers 4-pack

UPBOLT Jamming preventer for Cobra Siege and Cobra Adder (different variations). We are shipping 4 anti-jammers in 1 pack.

Cobra Siege variation requires UPBOLT magazine to be installed.

Cobra Adder variation works with standard Cobra Magazine (with UPBOLT extender installed or not).  Also, it should work with Jörg Sprave Cobra V2 magazine, but it is "officially not supported".

1. What problem will it solve?

For Cobra Adder this will prevent 99% of possible jammings due to the bolt moving too much to the back during reloading.

Those items are listed separately because one Jamming preventer might last a few hundred shots, so might be a need to replace it.

Please note, you can benefit from it even with Standard magazine.

3. Is this a reliable solution?

Yes, since this is a flexible part, it can stand on a bolt way and totally block the bolt from a potential move to the back, where it jams. Same time string can bend this part and reloading happens without interruption. 

4. Package content:

1. Four Jamming preventers
2. Small sandpaper piece

!!! note - glue for fixation is not included
