Can't find too much info on the web for anything but the proline series, and as the proline is apparently compatible with VSR-10 upgrades, can anyone chime in with confirmation of what the Sportline can take upgrade wise? been havin a hell of a time makin an upgrade list for it.

I'm in the same boat...

I'm also trying to find upgrade parts for the ASG M40A3. It seems like a great platform to upgrade on (plus it's cheap) but the parts are alluding me. You could try asking around on some of the other threads, but I haven't got any answers myself. If you find something though let me know

The sportsline ASG M40A3 can take these two parts:
SSG69 P2 High power springs 6 pcs.
Precision barrel, 6,03x465mm, for SSG 69

With that installed it'll do 500fps. It lifts a 0.40 OK out of box, and a 0.43 at a stretch.
I recommend lead wrapping the piston.

But yeah it's actually an ace rifle for no money. That spring and barrel are like 30usd together. Any ASG retailer can order them in.
