For sale is a Tokyo Marui MWS CQBR which has seen minimum use. It comes complete and has 8 magazines in total. 6 mags are the 35 round Marui mags and the other 2 are the 39 round Ace 1 Arms Pmags with full trades.  All the mags are leak free. Also included is a complete UAC bolt for cold weather use. 

The Marui bolt has a upgraded nozzle valve and I think it's a dynamic precision one but can't remember 100%. FPS will be gas dependant and the Pmags are unused.

You can check out badabing's youtube video on the UAC cold weather bolt for more info. FPS will be gas and weather dependant but should be stock MWS. The price is £800 shipped which is about £350 less than you would pay for the GBB and all the bits.

I'll try to fit everything into the original Marui box securely but if that turns out to be a pain in the arse I'll split it into 2 packages for postage.

Basically you will be buying a good to go package for 365 days a year.
