Sports Airsoft

A special sport within itself.

Me and a few friends are going to be forming a fireteam for competitive airsoft in our community. I'm going to be posting a full loadout here for a sniper/direct marksman with what I'm ordering eventually, and I'd like some recommendations and suggestions from anyone familiar with the sport.

Loadout:

USMC style plate carrier, four rifle magazine pouches, two pistol.

A&K U.S. Army SOCOM M24 w/ Novritsch internal tuning kit (working on figuring out compatibility)

Colt Special Forces 1911 Tactical, CO2 powered gas blowback w/ suppressor.

One smoke grenade, unsure the brand.

Combat shirt w/ IR Alaska flag on right shoulder, Punisher patch on left.

Condor Tactical hat w/ Punisher patch, OD green.

Multi cam mesh face mask.

Ballistic rated sunglasses.

Four extra rifle magazines, two extra pistol.

Handheld speedloader.

5-11 Tactical pants.

A pair of combat boots idk who the **** made them, got them from a friend xD

My main issue right now is figuring out the compatibility between tuning kits for the M24 rifle, so that the stock 400 feet per second velocity is boosted to 600, and the rifle doesn't break under the strain. I also have to do some testing because 600 FPS behind a .20 or .25 gram BB will have a very short flight span, and I want to figure out if I'm using .35 or .45 gram rounds to get the distance I need.
