KWA LM4 GBBR. Kwa KR9 PTR with extended barrel. 4 non leak mags. Great realistic internals with .22 cal recoil. Fun gun that everyone loves to shoot. Realistic bolt carrier and bolt lock. One of the most realistic and solid airsoft guns I’ve ever owned. Comes with multiple hop up kit replacements and slight modding for better feeding. I am selling because my tippmann air line went out and need to find a new gun for MilSim.
