Similar to my beretta AL390. There’s a tail on the end of the bolt carrier. Rather than having a regular buffer tube, the fight lite SCR has a buffer tube that comes out at an angle. Notice how the bolt tail and the grip and how are similar. I was trying to find an internal diagram, but it’s early and my google-fu isn’t warmed up. Otherwise it’s a regular AR. Normal URG, with the exception of the bolt carrier.How does that even work?
