Got it off of some guy used. He had broken two of the screws holding the magwell in place, thereby making the gun unusable without taping in the magazine. What's more, it seemed like he tried to take apart the rifle haphazardly, but didn't quite know what he was doing, unscrewing things at random.
I got the gun for 80 bucks. First thing I did when I got it was drill out the two screws, and put an ECHO 1 ASR upgrade kit, being APS2 compatible. Zero'd a scope, and was firing .36's. I really liked it. The heavy body made pulling the bolt back a lot easier, and having that huge nob to pull back the spring was easy too. I don't have pictures, but was hitting a 2 foot by 1 foot box at about 100 feet with every shot using .36s. Not bad for a stock barrel and rubber.
Brought it to the field. It shot twice before the cylinder snapped on me. I considered it to be an 80 dollar body kit at that point.
I just bought a PDI Hop Up Chamber, and am waiting for a 590 TB. Once I get that together (I already bought the Laylax PSS2 teflon cylinder), the rifle will be ready to go again, and I'll post a review.
