"Well, there's probably not much more I can tell you about GHK M4s since there have been many established reviews. However this very specific batch as of 2019 is different. You can easily tell if your serial number starts with an W (2019 batch) or K (2018 batch)


– Improved hard anodized matte finish, as oppose to the horrible thick shiny black coat of the 2018 batch. This new finish is thinner, but stronger and scratch resistant, simply spot on. Very nice looking indeed.
– Improved bolt catch and stronger metal insert on the bolt to ensure lock back.
– Insane gas efficiency, 1 fill will give you 3 - 4 mags.
– Comes with original bird cage flashhider and Colt engraved magazine base plate. Authentic!
– Markings are second to none, I especially love the stamped markings on the barrel. Well done.

Left to be desired:

– Quite weak spring, you'll notice when you pull the charging handle back and let it slam forward. But gladly, the gun recoil is not weak. I guess they did this to prolong the life of the parts. Aftermarket springs and heavier bolts are everywhere, so that's fine.
– Classic LE stock wobble, even the real steel has this issue, so no biggie. Easy fix with some tape around the inside. I guess it's authentic...
– Do yourself a favor and swap out for a better, nicer looking rear sight.
– Mine came with a misaligned rail... quite disappointing for a $550 gun. Caused by a chip. I'm asking for a replacement part.
