When the cover is mounted on the gun, you can use original iron sights (unless you mount optical device on rail).

No tools required from mounting on / removing off the gun.

Maintaing zero when ramoving from gun and re-attached on the gun (e.g cleaning, gun malfunction, ...).

Dust cover PRO provides additional firmness, e.g. when drop. Dust Cover PRO is thick-walled which results in increased protection of original dust cover. When Dust Cover PRO is damaged, you can take it off the gun easily and continue fire as the gun is still working with original metal sheet cover and recoil spring assembly. This doesn't offer any other dust cover on the market. They are all replacable parts with recoil spring assembly and if such cover is broken, you have to take it off the gun including springs assembly. You cannot use your gun when it happens.

As mentioned above - Dust Cover PRO is FAIL SAFE - in case of its damage or malfunction you can still continue shooting.

Dust Cover PRO maintain reliability of gun thanks the original assembly of recoil and firing springs which are well made by manufacturer of the gun.

Dust Cover PRO has sleek design which reduces possibility of snag.


If you decide to use rifle scope on top rail and you would like to have red dot mounted as well, Dust Cover PRO is ready for side mini rail. This mini rail is 40 mm long (1.57 inch) which is enough for Docter Red Dot sight, Burris FastFire and other small red dots (limit is weight up to 50 grams).

Mounting points are ambidextrous. Once you tilt the gun about 45 degrees to side, mini rail is aligned with barrel axis.


Dust cover PRO can be used on guns with custom finish like blued or re-painted. Its design allows useage on guns which width of frame is between 35.7 mm and 36.5 mm (1.41 to 1.437 inch). If your gun exceeds this size after customization, please specify its dimension in your order and I will prepare a special piece for you.


All bolts and nuts are secured against loosing caused by vibrations or shocks when using a gun.
