Wont interfere with stock gas setup
Another wonderful product from opsgear, I ordered this UMP mag over spring break and I have been very happy with it. It has a solid metal construction and includes everything needed to install it, it was a breeze to install, took less than 5 mins. i can field strip my quite fast still with this mag. it doesnt interfere with the stock airline which is good. It has amazing looks that go great with my g36/Mp-5 setup. It also makes a sturdy forgrip to hold on to.
Great product, if youre making a SMG type weapon, you cant beat the looks of this mag.
