After my last second hand purchase I wasn't expecting too much...
There's a couple of little bits missing, but that's an excuse to buy shiny cnc doodads. It even runs and shoots OK. The gearbox doesn't show any wear, and there's never going to be a problem fitting batteries in that stock! Quite pleased for £120 including postage.
Just got a T1 for my scorpion and just waiting for my 3dsoft handguard. Purchased some pouches as well to enable me to run both my M4 & Scorpion from the same rig.
