Here is a quick Review of my ATP after a couple skirmishes and a lot of tinkering.
Pros:
Light weight
Gas consumption
Backwards compatible
Available Holsters
Accuracy
Cons:
Requires a little work to function right out of the box
Very Dry out of the box
Cost of Mags (Kinda standard complaint with most GBBP)
Range is limited
Grip angle (Common complaint of all Glock models for me, even with my RS version)
Hop Up Adjustment (Tool neded to do correctly and easily)
I was happy to receive my unit from Airsoft-barracks.com at the Combat City North vs South Game a couple weeks back. U
