since springs all cost the same. I have a feeling Spring ratings are based on Meters per Second for 0.2 BBs. To convert it to FPS just take the rating and x3.3.
SP100, 330-350
SP110, 360-380 (the maximum a 8.4V battery can pull)
SP120, 390-410 (.2) requires 9.6V battery
SP130, 440-460 (0.23) (maximum stock gears can safely operate)
SP140, 470-490 (0.23)
SP150, 510-530
SP160, 550-580
SP170, 580-600
Type-0 (Closed), 450mm/580mm (27.1cc)
Type-1 (tip hole)
Type-2 (XM; 4/5 hole), 364mm/460mm
Type-3 (3/4 hole; M4), 229mm/430mm (17cc)
Type-4 (MP5k; 1/2 hole), 110mm/170mm (9cc)
Yet to be verified and other sources found.
Systema Prices I can find (6.04mm).
110mm Php1170
141mm 1485
247mm 1575
285mm 1440
363mm 1665
455mm 1620
469mm 1665
509mm-550mm Php1800 (according to retail price on my barrel they are the same! Y3800)
I have the feeling the suppliers provide this to the retailers at 3/4rds the “suggested retail cost”. I recommend trying negotiate up to Yen to Peso price up to 10% less.
So technically my 550mm cost the supplier 1800.
G3 problems. So My G3 should be by the spring 130 have a base FPS of 426. Adding the Tight Barrel Performance, it should average at about [email protected]. Using 0.25 BBs, that should have about 405-425. When I first got this from the Smith it was about 400-410. I called him up and told him, he says there must be some debris left in the hop up. This happend around July when the Gun Ban ended.
At 390 to [email protected] since last few games. I’m missing some 20-40fps, even accounting for spring degradation.
Anyway I’ll try a simple teflon tape fix:

A friend is lending me their extra chrono. I
I don’t wan’t to make another purchase but the only way I can find out if my work is right is with a chrono.
Someone in Filairsoft was asking for a upgraded gun for 5500, either an AK, M4, HK416… Good luck. An upgraded brand new (fresh from the gunsmith) would cost 10k.
