Saw this at pinoyairsoft.org. Interesting review with this conclusion: "The CQBR is a very heavy rifle and if you think that the JG Spetsnaz is heavy then don't get this gun. It's very much front heavy. With the stock battery, the ROF is slower than other stock guns. This may be attributed to the long and stiff spring they used. Also, the internals need more lubrication. You will also notice that it doesn't shoot that accurately thanks to the mismatched cylinder. I suggest getting a type 2 cylinder from a well r6 or r5.

If you've salivated over the CA CQB like I have, you will appreciate this gun. If you just want a CQB weapon I suggest you get an M733 instead, unless you don't mind the weight.

FPS results, by the way are 310 fps on 0.25g bb's. Consistent fps with deviations of just 3-5 fps. 310 fps on 0.25g translates to 347fps on 0.2g btw. And that's with air leaks in the cylinder head."
