Well those barrels are a ridiculous .694, more of an extended flash hider than an actual barrel. The only purpose they serve is to let you add the fake silencer that clamps on them.
That barrel would make the G2 as large as a regular marker, without the interchangeable bore sizes or BPS rate of a regular marker.
If that were my only beef, I'd probably keep the gun.
I got lucky and received everything in fine order(box foam and all) from extremez. I hope they don't go the way of Armotech and learn from Tiberius instead! Customer service is as important as product.
