New M4A1 GBB?

[M_P]

Guys I appreciate all the feedback. But I may go with the npas solution cuz it sounds alot easier. And I don't want to make any modifications to the gun whatsoever xD

Just so you're aware, I'd highly recommend picking up a couple of spare plastic loading nozzles, the WE ones can range from lasting a few hundred rounds up to a several thousand depending on how lucky you are. Worth having at least on spare just in case.

Mil spec Solutions last time I checked £275 for one + NPAS is included as M_P said. Pretty sure upgrading a GBBR wouldn't be hard anyway though? I don't know what fitting the NPAS involves but must be easier than modifying AEGs

It's pretty simple, yeah.

Field strip it to get to the bolt, undo the nozzle guides on the bolt and push the pin out holding the nozzle return spring.

Once the nozzle's out, push the pin through to separate it into two halves.

Drop the valve and spring out of the front half, replace with NPAS.

Reassemble.

Only tricky bit is lining the pins up with the nozzle return spring.

The G&G GBB M4s are actualy pretty good, the mags almost never leak and it has a decent kick. Ive had it for a year and only had 1 problem which was that the hammer spring flew off while i was transporting it in a backpack in two halfs.

Its good for the price but it doesnt have a full cycling bolt, it only goes about halfway back if your looking for realism with the action then you might want a WE but i have seen multiple problems with the WE at my local field.

Be different...buy a scar ?

Mine has the npas and ive set it to 325fps so if its warm ive got leeway for extra power.
