The barrel is an E.R. Shaw with carbine gas, chrome-lined, 1/9 twist. I am planning to rebuild it soon with a 604 upper and partial fence lower receiver from Nodak Spud. Just waiting for the lower to come.
Magpul UBR stock. I love the thing, it's a bit pricey but so worth it! Helps to balance the rifle with the long handguard. If you are looking to buy one it comes with the tube, just need a buffer and spring.
You can thank me for that lol I was just going to buy the barrel, but then those dried up. It is probably the slowest thing I have ever ordered from midway. Probably has something to do with Black Friday.
