So what is real and what is fake(knock-off) on that AR?
I doubt you are running a $400+ muzzle break.
Yeah, it's airsoft, should have reiterated!
As to what is "fake" it all is... I don't have any real steel kit on there as most of it is ITAR restricted.
The Magpul stuff on there is licensed by Magpul though (Magpul PTS), so it's as genuine as can be... I have a PTS CTR, MIAD, P-Mags, ASAP, AFG2 and a couple of XTM covers... The lower is also a licensed PTS version. As I understand it the real steel ones were produced in really limited amounts, with most being rejected at QA because they were out of spec. More Airsoft ones probably exist than real!
The rail is a licensed Daniel Defence one, and to be honest the quality of the alloy is he only thing that sets it apart... That is the biggest thing I know, but it's bang on otherwise, quite impressive.
That T-1 is a replica too... Pretty sure that's unlicensed too, but it's the best copy on the market. Would buy a real one, but it hurts my soul to drop that kinda cash on an optic for a gun that won't shoot a 1' group beyond 30m...
The TT break is also a knock off... I love KAC and would go out of my way to get a licensed one if it existed!
