I have one. Havent shot it in 3+ years if that says anything. The sights, trigger, and build quality kinda suck. The bolt is also huge so there is a lot of reciprocating mass.Gen2 seems to be a little nicer built but still have low height sights and the same trigger. I bought a trigger kit but didnt get around to installing it since i dont care to shoot it unless the silhouette side opens up to pcc's.
Its cool because it folds and fits in some 17" laptop cases. Its also light, low profile, and 'low drag' because of the vertical charging handle. I have it crammed in a pelican 1470 where the muzzle touches the case but a slightly larger pelican 1490 can comfortably fit a sub2k ,glock 17, and probably 5-6 ext mags and a few standard size mags, not including the ones in the magwells.
That trunk mount is awesome.
