FAQ
What does FAIL SAFE mean?
The original sheet cover with the recoil and hammer spring assembly stays on the rifle. If the cover is damaged you simply remove it and keep shooting – it never affects the rifle's function.
Do I need tools or a gunsmith?
No. Fitting and removal are tool-free with no modification to the rifle, and take a few seconds.
Does it fit a refinished rifle?
Yes, it works with receiver widths of 35.7–36.5 mm at the bolt area, so blued or repainted rifles too. Wider rifles are handled individually.
Can I run a scope and a red dot together?
Yes, the cover is ready for the 38 mm side mini rail that takes a red dot up to 50 g (Docter, Burris FastFire…).
