Umarex Glock 17 Gen5 MOS GBB

This Umarex Glock 17 Gen5 MOS GBB airsoft replica is a nearly identical copy of the firearm carrying the same name. It features a semi-automatic firing mode that allows you to quickly fire off 6 mm BB’s and it comes supplied with a magazine that has a capacity of 20 BBs. That gas magazine has an external follower that can be pulled down manually, which allows for easy loading. The replica has blowback that feels just right and it features the same trigger safety that the real steel Glock 17 has.

This airsoft replica is made of black anodised aluminium that has improved corrosion resistance. The grip is made of synthetic material, granting a decent balance to the Umarex Glock 17 Gen5 MOS GBB. It has a total length of 204 mm, resulting in a sight line with a decent length. This means you can aim just fine with the front and rear sight. However, installing a red dot onto the replica is incredibly easy as well. That’s because this MOS-version -which stands for Modular Optic System- features a removable plate on the rear of the slide. You can easily replace that plate with an adapter plate for a red dot by Docter, Trijicon, C-More or Leupold.

The Glock 17 Gen5 MOS GBB by Umarex has a grip that’s covered in a rough texture on all sides, which provides slightly more grip. Both lefthanded and righthanded airsofters can comfortably use this airsoft replica, but it might require a little alteration. The slide lock can be operated from both the left side and the right side of the frame out of the box and the magazine pin can be reversed from the left side of the frame to the right side. The Weaver/Picatinny accessory rail located on the bottom of the fore-end can be used to mount something like a lamp or a laser. Speaking of adjustability; this airsoft replica features an adjustable hop-up. You will have to remove the slide, as the adjustable hop-up is attached to the inner barrel.
