"EXCELLENT RIFLE for it's price. A bit expensive, but definitely worth it. Now. The internals are good, previous G&P issues have been resolved in this. The externals are very, very nice, as G&P is known for its externals in the airsoft world. Rock solid fire rate @ 1500 RPM (25 RPS) with a G&P 9.6V 1600mAH battery. Gun is compact, lightweight and rather accurate. Flip up front sights can tightened if needed. Also has a military adjustable rear sight. AR15 Patent Pending Lite Rail (7.0) in the front offering plenty of rail space. Pistol grip is somewhat ergonomic, BUT will heat up once the gun has been used for some bit. Included with a G&P Mid Cap!

+390 stock FPS, broke in to 365 at times
+AR15 Lite Rail offering loads of rail space
+Very nice externals
+Very decent RoF with a 9.6V 1600maH
+Is a high-end gun, so show off with it!
+Comes with a very nice mid cap, not just some crappy plastic mag the company halfheart sends you
+Definitely an eye-grabber when you full auto before a match starts, apart from the P*.
+Tan color is sexy

-30 FPS drop after break-in, which means it drops from a high FPS outdoor gun to a low FPS/very high FPS indoor gun.
-Pistol Grip gets hot after a while of shooting
---My wheel hop up isn't the best, always seems to be moving, big minus
-Stubby Raider grip that comes along is a bit short for my hand

OVERALL: 8.5/10
Good price for outstanding externals
Nice FPS
Very nice FPS
Good overall, intermediate to advanced rifle.

"Great rifle! Pros and cons below:

+Nice externals (feels solid but also quite light)
+Compatible with many M4 mags.
+Plenty of rail space
+Comes with rail padding and a stubby foregrip
+PERFECT RPS for OUTDOORS (385-400, will lower once it breaks-in)
+Runs good with a 9.6v or 10.8v.
+Can change to a different stock for different battery types.

-Receivers are easily scratched, so be careful.
-Maybe a bit overpriced? $280-300 would be good.

"This gun is worth every penny, it's amazing (big step up from a dboy scar)
the tan is a little bit darker than the pics show,

accuracy- fantastic, repeatedly hit a 3 inch target from 50ft
power- seems harder than 350 fps, not the best but accuracy and rof make it up
rof- insane, used a tenergy 9.6v 1600mah battery (shoots faster than most guns with a lipo).............._A 1600MAH BATTERY IS THE BIGGEST BATTERY THAT WILL FIT IN THE STOCK_
unless you use a buffertube lipo...not recommended
or you can take off a cheek rest on the stock and fit ANY SIZE battery with a batt bag or some tape
