They sure are. I got the full kit including the BCG from Joe Bob Outfitters and saved a few bucks, but it was still some money. Fortunately, the stock and tube are pretty reasonable priced from LWRC. It is period the end the shortest you can get a function AR and that was a huge goal for me. I fold this thing up into a discrete bag and I haven't had to use a "gun bag" in the last year. Makes it easier with close neighbors, or heck, even just visiting my parents halfway across the state.
I'll say their customer service is pretty spot on. I had an issue with the original spring not playing nice with my subsonic 300blk loads and gave them a call. Went right to a guys cell phone which was promptly answered even though he was at a trade show! I got the replacement spring I needed and have been happily able to run my subsonics even unsupressed.
