guess im one of the luck ones who has yet to get addicted to modding yet. all together i would say only about $300 so far on gun upgrades alone.....not counting my personal equipment upgrades.
Flatline with Battle Shroud new-$100
E-Grip used- $50...thanks to Cleric
Tech T Ratchet-$35
5 Point Stock-$35
oober nice Forgrip-$30
Springs+Seals-$20
$20 on a Sling.....more for comfort then gun mod i guess
oh an like $10 bucks in Emmry Paper to polish insides.

ahh ive got a bad feeling though that more of my paycheck is gonna be goin to finish modding this thing.....Help...isnt there a stop modding patch out there i can use. lol
