Double Bell Full Metal XM177 Airsoft AEG Rifle

"Its not a XM177, but GAU 5A! Even BETTER than xm177. Has no forward assist, making it more of the GAU 5 and a rare bird indeed!!! No MOSFET, but I got a PERUN hybrid and clicker, well worth it! Don't let the low price fool you! I bought one and took it all the way down. ALL the parts are quality:
CNC O-Ring Nozzle,
2 o-ring ported aluminum piston head
2 o-ring alluminum C head.
Good looking piston, need to drop a tooth for AOE.
Good looking gears that were shimmed from the factory, and not bad at that.
Great externals, i am going to repaint and electro stencil the colt markings on to receiver
Gearbox is HEAVY, lots of metal.
Motor does not appear to be Neo, but still pretty clickily.
Bearings look good, time will tell.

Pros:
Shoots great out of the box, hops 28's. gearbox is a lot better than a CYMA.
Rare model, its a GAU 5A!!!
Great starting point for a accurate replica of a GAU-5A or use as is.
Great air seal out of the box.
Shoots 400-410 fps out of box.
Best value in airsoft that I have found in a long time.

Cons:
No Mosfet.
Fat handguards. Replaced with proper ones.
Polymer stock, not aluminum, but you can find one on line to make this great if that matters to you.
Tamya connectors, change to Deans.
May want to grind a tooth off the piston and angle the other...
