G&G Armament SGR 556 G3 Split Gearbox Airsoft M4 AEG Rifle
(Color: Black)

"I have this gun and it feels really solid, and shoots great. There is slight play between the upper receiver and handguard on mine at least but aside from that the gun is solid and feels very high quality. I don't like that the hopup adjuster needs a screwdriver so that means it'll be a pain to adjust mid-play.

I love the split gearbox, but I already blew the mosfet by running it on full auto with the gearbox open on an 11.1v 25c battery (only did a ~5s full auto burst before the mosfet blew) so it was either too much battery or you shouldn't run the gun open like that except in semi auto to reset the gears to prep for closing.

A new ETU was reasonably priced ($40 at time of writing) and easy enough to change out.

"I purchased this gun at my local Airsoft felid and I love this gun beside the few but significant issues it has.
The most major issue I noticed after about a year of wear is the threads on the buffer tube wear down making the whole stock wiggle and tun a lot, and you can’t even buy a replacement with out contacting the factory. The front handguard does have a bit of a wiggle no matter how much it’s tighten down but it’s not significant enough to cause issues. Where the pins connect the upper receiver to the lower have ended up snapping off the uppers connecting joints. Other than these major and slightly annoying issues this gun works great for not being able to upgrade it easily. Shoots consistently, works great with most mags, and has an easy programmable system. For the price I wouldn't recommend this as a starter gun but a fun gun to have in your collection.
