This is the Grill Kill Flash for the STPR Red Dot Sight Cover. It slides into the front slot of this cover:
Get the ultimate sight protection with our stainless steel kill flash / scope cover. The Airsoft3D stainless steel grill (5mm opening) is exceptionally strong and will stop airsoft BB's and paintballs from impacting your red dot sight directly. And the grill design provides maximum visibility for fastest target acquisition. The stainless steel material is virtually indestructible. You'll never have to replace this kill flash due to dents, wear, and tear.
Note that this protective kill flash reduces the chances of your red dot sight being destroyed. But it may not protect the sight completely from shattered BB's, projectiles of smaller sizes, shock, and other hazards.
Airsoft equipment used for the illustration of this scope protector are not included.
