NY City Police raid house, find arsenal of weapons and ammo

[MrAK]

“A Colt Light Machine Gun front end” Can someone point out/explain that one for me ?
I saw what could be a couple of SBR ARs, but “a Colt Light Machine Gun front end” ?

Looks like it’s gonna be this firearm located in the center of the pic

That doesn’t look like the stockpile of a gang banger’s underground arms dealer to me
