EXTREME blowback up the vert feed
No sticky grips
After using this gun for 3-5 months, I would deffintaly recommend it to anyone wanting a gun. The only major problem is the very bad blow-back up the vert feed cuasing a lot of chopping if not carefull.. This can be solved by setting the BPS to around 8 or buying a force feed hopper (Evo 2 or Halo). My experince with the Evo2 is that it is only realiable upto 13bps due to blowback. As of yet no one makes any kind of grips for the M92 frame, but the stock one isnt all that bad. The game timer and shot counter are very nice features for tounery ppl on a budget(cant afford expensive guns). Also the gun can be put into safe mode withOUT turning it off.
All around this gun is good for newbies as well as experinced players. Simple realiable design with the speed needed for todays games. i give it a 8out of 10 b/c its a blowback but a very nice one at that.
