Hi I'm looking to buy a new m4a1. But I was looking to find a GBB M4A1 around a £200 price mark. Any recommendations?

 
I think there's a part called an NPAS which can help lower FPS? I'm not absolutely sure on that one though.

 
You can either use an npas bolt (not an ideal solution as i think that the setting gets put off over time, like a bad hop up), a 1j bolt, which lets less gas down the barrel, or you can install a shorter or a wider barrel

 
Depends on the NPAS and how much you're willing to spend. The newer RA-Tech ones are solid, but other brands aren't always so much.

Also they're a great deal of money. Not for the faint hearted.

They're only £70. I guess it depends on what you call a "great deal of money" but if you're buying a GBB rifle then an NPAS is a drop in the ocean...

Errrmmm...if you say so. I thought you were saying that an NPAS was expensive so I pointed out that going GBB is expensive anyway. If that was your point then yes, yes we do agree (kaloo! kalay! What excellent fortune).

Of course if that's not what you were trying to say then you're wrong. Totally wrong. *skips off with fingers in ears singing "LA LA LAAA I'M NOT LISTENING TO YOOOOUUUUUU"*

 
Oh I know all too well how much a GBBR costs to upgrade, so yeh.

Screw the metal nozzles they're a total waste of money. Come with their own set of issues that require you to upgrade other parts.

Plastic nozzles are ten a penny and are perfectly fine as well as not requiring any modification to fit or function properly.

 
So I'm thinking of getting a WE M4A1 GBBR "Open - Bolt" which is £299.99 which if I recollect is a good price for a WE GBBR. So... are you guys suggesting an NPAS install won't be beneficial for my gun. If not then what do you suppose I do to bring the fps to 350?

 
As i mentioned, longer/tighter barrel increases fps, shorter/wider barrel reduces fps.

You can also buy a 1j bolt which is a nozzle that reduces power by letting less gas through.

If youre short of cash but have good tools, you can try cutting the barrel down yourself, though this is a minefield and needs much care and research

 
£15 NPAS valves are fine.

l use them in both my WE GBBRs. No issues here in over a year.

Get it from milspec solutions and it will come with a free npas already installed, then you'll be set for playing straight awar

 
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
