I'm new to gun-modding and would like some input from some of you experienced "tinkerers". I'm looking to purchase an EMG Hellbreaker 10" for use as a primary in cqb and field games. I would like for the rifle to be a reliable and accurate choice for either situation. I'd like to be able to get it to 500 fps (and retain the ability to drop down to 300 fps or so). Price isn't really a factor, but I'm sure there are some mods that work just as well as their more expensive counter-parts. I just want a rifle that can perform as well as (if not better than) most weapons you commonly see in those situations. Does anyone know from experience if/where the Hellbreaker falls short? What, if any, upgrades would you install if you were making this rifle for yourself for those types of games? Which sites/articles would you suggest reading up on for modding this style rifle so when I do open her up, I'm not "going in blind". Any help would be greatly appreciated, and if there are any questions please ask them. After the build is complete I will make a few videos, gameplay included. Thanks.
