"i won this gun at the last game i went too and its just great it shoots hard and fast. only used it a few times now but the times i have used it, its been just great the only thing tho is that the clip that came with it is not feeding right and i have to old it in place in order for it to work but i got new clips and fixed it right away
overall its a great gun and right out of the box too:D

"I've had this thing for 2-3 months now as I've been waiting to put out a review on here.
First off. Its A&K. Now, I've heard terrible things about them and people have compared them to Aftermath.. ew. However I think this thing is very high quality. Metal receiver.. practically all metal parts that a real steel would have. I've put roughly eh 15000-20000 rounds through this and have fielded it a couple times as well. I've put a matrix/prommy 6.03 450mm barrel in here and its beautiful. It sticks out not even 60mm of the original outer barrel so I've simply put a stubby on the end. The stock accuracy is nice for a stock, but if you're keeping this long term it should be upgraded.

Full Metal Receiver
Full Metal Outer Barrel
Full Metal Folding Stock (Very little wobble)
Nice Stock Accuracy

Tight Battery Space (Front wired)
Awkward Pistol Grip/Motor Compartment
Lowish ROF
A&K? --Internals so far are fine--

Overall a very good buy for 180 being that its full metal where it counts. 5/5
