I'd highly recommend the E-grip and rip clip to get the most out of your Delta. Also get the X-7 hopper to reduce your gun's overall cross sectional area
Works excellent out of the box
okay, so honestly i never really did play with the gun in it's true stock form, i put my upgrades immediately on. However, with the upgrades the gun performs wonderfully, and is the only gun out of the 4 or 5 that i have that I actually use. Out of maybe the 10,000 rounds I've shot with the gun, I've chopped maybe 4? But it's not a big deal, it simply powers through them without a problem even with the stock barrel. Regarding the jams. This problem seems to want to happen at higher rates of fire, since this is with the upgraded Rip Clip, I will not deduct points from the overall weapon.
Excellent gun, highly recommended for anyone looking to increase their milsim arsenal
