I remember LS made a whole series of kits from the early west to the 70s. Have you seen another kit of that one?
They pop up on eBay in the $175-250 range intermittently.
The L/S M16A1 kit is a fussy uilt, and it really wants use of metal tubing to reinforce several of the joints, and rather a lont of gluing threaded connections. But, it's spot on for dimensions.
The L/S XM177 kit is actually much sturdier--just about twice as rare anymore if not three or four times.
The L/S kit of the AKM (which, perversely, has an orange AK-74 magazine) is very sturdy, and a good solid build.
