Left to right top row - Mp5, M4 body mod, called an Iku Zuchi, L85 it's a shorter version of the 86, ak74 fullstock, M16 with a 9x Sniper scope on it, and an L96.
Left to right bottom row - Glock 23, Glock18c (I tore apart the blowback unit in a week, full auto killed it horribly) Tactical 1911, 2x Sigma's, Desert Eagle with a modified and extended barrel (Shoots 470 FPS with those upgrades) and my trusty mp7 that I upgraded with a sniper spring.
Guns that aren't there but we now have - 5x Sig 552's, Ak47 with full RIS rails on the front barrel, VSR-10, an M249 with an M203 grenade launcher, and of course 6 grenade shells that shoot 120 BB's per shot at 300 FPS.
And yeah MOFO, me and my brother do that, he even owns an airsoft mask that's a replica of Rios'. We work well as a team, and more often than not get a excrement load of kills.
