What's a product that completely changed your game day experience?

A gun-case. Drove me nuts lugging around all my kit until I got a decent sized one for £60 that everything could fit into.

It's comms and team mates I think for me. I've played alot of games solo, and being able to communicate and co-ordinate has been a game changer for me.

One of the crank speed loaders. I think mine is the Nuprol one and it's made bombing up so much quicker.

I agree with Matt, Comms for sure! Made doing missions/quests so much easier with a team rather than being that one dude that no one can reach because he has no radio!
