"SA-E03. I've only had one game with it but I like it a lot, It reminds me of the standard issue M4 I had in the service. Downsides is that the foregrip is wobbly, the rail covers basically fell off, and the springs are quite difficult to change as they require the buttstock to be remove.

I chrono'd mine:
M90: ~305 fps
Stock: ~365 fps

"Picked up the PDW SA-E10 for indoor CQB. Have to say you're getting a lot of bang for your buck with going with the Specna Arms Edge rifles. Mine came with a vertical grip, 2 midcaps, m90 spring, deans to tamiya adapter, unjamming/cleaning rod, manual, and QC sheet. The QC sheet for fps was off by -20fps which I thought was hilarious.

With the stock spring I was getting 360 fps avg which is slightly too hot for CQB. The included M90 spring dropped the fps too much, swapped it out with one of my other spares to get 350. The quick change spring through the buffer tube is made simple and not overly convoluted. Other manufacturers really should follow suit.

Shooting is snappy with a 11.1v Lipo. I haven't locked up the gearbox after pulling the trigger in quick succession. What's nice is that this compression in the rifle is superb so shots are verrryyy consistent. The hop up is also very nice and easy to operate with the rotary style unit. Set it and forget it and it shoots laser beams.

I'm happy to see that the pistol grip isn't the standard A2 style. It's slightly more vertical so your wrist is in a more natural position during operation. The included mid caps have a snug fit but, contrary to popular belief, I prefer to have a slight wobble. The capacity is pretty low at about 120 rounds. My BAMF mags need a little fumbling around to get it right but once its in, it stays in and feeds wonderfully. Construction of the midcaps are done well, though. A thick polymer with their SA logos etched in make the finish really neat.

Battery space leaves a lot to be desired primarily due to the Gate MOSFET being housed in the buffer tube. I had purchased a larger stock to fix this. The metal used for the receivers feels weighty but also really cheap. Not a big deal to me but I've held much lighter full metal replicas like the Valken Alloy Series. But, with a $200 price tag this is a minor gripe. I will say that after pulling back the charging handle for the first time, the tab that holds the dust cover closed broke and cannot be closed. It is what it is, but again.. It's $200.

All in all, I'm very pleased with what you get in the box. I've had no problems with the gear box and works better than expected given the low cost of admission. I'm astounded that SA was able to make so many different variants of the Edge series so there really is one for every one. Keep it up.
