WE M4 with Norvick hpa kit

We M4 gbbr with Norvick hpa kit. Basicly a gbbr with all its functions, no cooldown and slightly modified aeg magazines.
Bolt lock on empty works with modified g&g G2 magazines. Can be also used with modified normal aeg magazines without bolt lock. Comes with one already modified G2 magazine. Additional mags can be purchased also 27€/pcs.
You can also buy and modify magazines yourself. There is a YouTube video explaining how to do the mod.

With WE original boltcarrier and nozzle with DIY npas to adjust muzzle velocity. Can also be adjusted with pressure from the regulator. Adjustment range at 120psi and 0.28g BB is 0.8-1.4J. If you plan to use +140psi I recommend to buy and install a real steel buffertube. Original We buffertube will break at some point with higher pressure due to being made out of weaker material.

With Ra-tech stainless steel inner barrel and maple leaf monster hopup rubber. Steel parts in the triggergroup and buffer with weights to eliminate bolt bounce.
Steel outer barrel, 10" urx4 style rail. You can choose whether you want us or eu Foster fitting for the hose.

In good working condition. Used and has signs of wear as can be seen in the pictures.

Package includes what you see in the pictures (+  additional magazines if you want to purchase them )
