Well, the legal FPS for an airsoft gun is 450, but you can get snipers, AEG's, etc. that run up to 600 FPS and beyond.
go for the m14, unless its cheap looking.
I don't no about spring, but the Green Gas M700 Sniper Rifle Competition Professional Airsoft gun, has 720-FPS!!!! And the, Spring CSI L96 Bolt Action Airsoft Sniper Rifle, has 550-FPS. They are both from, Hobby Tron.com
yes you just need to put a worse spring in it
Any spring Airsoft gun is likely to shoot <200 FPS with the exception of snipers. Remember, FPS only influences muzzle velocity. As far as range is concerned, air resistance compensates, and a higher FPS only allows you to have a heavier BB. I own a Tokyo Marui Scar-H and it shoots 299.8 FPS, but is deadly accurate, much more than my M4A1 which does 370. Honestly, get an AEG if you really want higher FPS, it DOES make people call their hits hehe
No, The battery size determines the Rate of Fire or how fast it shoots. The fps is determined by the spring.
most cheap spring guns at walmart have very low velocity
MB03 by well
Yes. All you need to do is take disassemble your airsoft, take out the spring, and buy a newer, better one. I reccomend all airsoft at Evike.com.
400+
No. Aspects which determine how powerful an airsoft gun is actually it's spring (stronger/harder the spring means bigger fps), compression (better compression = better fps), and weight of the BBs we use (heavier BBs in the same fps can deliver bigger energy).Edit: If a gun that is automatic in real life is spring and very inexpensive, it is probably cheaply made and therefore almost definitely weak. However, "manual" guns that are spring are usually at least fairly powerful, such as bolt action sniper rifles.
that is way to hot for any airsoft field. my fields limit on snipers is 550 fps and you still cant shoot people within a 75 yard radius. if your just shooting targets its fine but if you want to actually play airsoft downgrade it. Theres no way your airsoft gun shoots at 1500 fps, the strongest airsoft gun i ever saw shot at about 550 and it was upgraded, i know some shoot close to 800 fps but those ones cost like 2 000$.
