I have one with the LMT stock , Had it a couple of years,and its been spot on ,ok I've played about with it has a different front RIS tight bore and hop up , the gear box is next ,for the money its been a great gun trades and the body feels fine on mine Christ I'm a lump of a block and I've landed on it a few times and it still not broken, no wobble on the stock or front Ris...never misfeed and takes just about every mag you can buy, not a lot more you can want as for G&G the front ends fixed so your stuck with it ...
