This is our upgraded "Bolt to Recoil Spring" link.

I must admit, I have photographed more interesting looking objects but this part is an essential item in ensuring total reliability of your CX4.

If the original plastic part fails you do not have even a single-shot carbine, the gun is totally disabled.

This upgrade part is made of bronze and it will last forever. As you may know the use of bronze in firearms has a long history, reaching back to the first firearms ever produced, since the metal is tough and corrosion resistant.

This part is very simply installed and I recommend that it be fitted along with our steel guide-rod upgrade.
