I recently got into Airsoft and bought my first rifle, a G&G Combat Machines CM16 Raider Long. According to the Evike website this particular rifle is rated at 340 to 400fps. Mine clocks in at approx. 315fps. Apparently the shorter barrel CQB has a higher fps but if anything that means the CQB should be closer to 400fps while my Long version should be shooting around 340fps.
The Raider apparently comes with an M100 spring so I figured if M100 = 100% and 315fps, then M110 = 110% & 345fps. This would be an ideal muzzle velocity for my indoor range (Tac City in South El Monte) which has a maximum limit of 350fps.
However, am I making a newbie mistake? Would an upgrade to an M110 spring not actually give me a 10% increase in fps over an M100 spring?
If not, being a Newbie, what are some relatively easy & inexpensive ways I can tweak my CM16 to increase its FPS.
I read the Sticky Thread about achieving 100% Air Seal in the gearbox.
Would this be a good place to start?
