Joe Toys presents the GHK M4 URG-I MK16 SOPMOD Block 3 Gas Blowback Rifle that has been made available in the market recently. Text is machine translated from Chinese so it's a bit confusing... "In recent years, GHK AIRSOFT has been very enterprising and has released two m4 gbbrs at once, namely M4 sopmod block 3 mk16 urg-i 14.5-inch and 10.3-inch versions. The original Colt authorizes the horse logo, Geissele mk16 urg-i Rail and cocking handle. You don’t need to buy additional parts in one step and install it yourself. Although the price belongs to Zhongjie, it saves you the cost of installing additional parts and the internal parts are all steel It's very content. I want to be stiff and easy to go on. I like it myself."
