The vendor roll. Firefly is great for crowd control. Extended mag and triple tap means it's a dps monster. Hand laid stock really isn't needed. There is barely any recoil as it is. Buy the vendor roll because we are most likely getting a new vendor stock in April. Yours is very good, however smallbore really isn't needed as the range and stability are already excellent, and you don't want to slow the reload speed or reduce the mag size at all. You also don't have the best sights.
