  1. Super sweet GBB airsoft rifle 4 Star Review

    Posted by on Feb 14th 2017

    This is a sweet GBB airsoft rifle.

    I had some problems with it at first (magazine lip shattered inside the gun), but customer service hooked me up.

    I love this gun. It needs lots of cleaning or it will occasionally will chop a BB, but it is so easy to take apart it is easily fixed.

    I tried to upgrade many of the arts to real-steel parts, but be advised that many of the parts are NOT MILSPEC.

    The ones that are: pistol grip, butt stock, dust cover, castle nut, end plate (kinda - aftermarket magpul fits, but doesn't fit flush)

    The parts that aren't milspec (can't be replaced: Take-down pins, safety selector assembly (too small), forward assist (too small).

    I ended up gold plating all the non milspec parts along with the endplate and castle nut. Looks really nice against the matt black Mega Arms finish.

    IMHO I really like the matt black finish on the upper and lower receivers.

    Gun shoots hard and shoots like a laser.

    You can put up to 40 secnds of Green gas in the mags, I recommend refilling it at every BB refill. I can make it through 2.5 mags before I run out, but it starts losing power at around 1.5-2 mags, so just fill it up.

    Awesome GBB gun. If you don't like working on guns and cleaning, it isn't for you. If you do - then this will become a favorite in your collection.
