Sunproject M40 A1 upgrades

[Jono77]

Hi, I mainly only do target shooting for fun/relax nowadays so I have a very nice air-rifle and I bought myself an M40 (simply because I like the look) for safe shooting.

Thing is I want to get some more accuracy and power out of the thing. I'm still only on 0.25g BBs and the thing probably fires about 300 fps.

I used to make all my upgrades but I leave my job in the new year and wont have access to the machine tools anymore so wondering what I can buy to liven the gun up a bit.

Any M40 owners have any advice ?

Much appreciated

PDI do everything you need bud. Google it and look out for firing x's.

Good luck, and btw - very jealous of your S.P. M40

Thanks, it's a nice gun, a few build issues but overall nice.

Thing is a lot of stuff is discontinued

What am I looking for in particular, just a spring upgrade ?

Sorry but I've been out of airsoft so long I can't remember anything to do with the things !
