THESE ARE BUILT TO ORDER.
Approximately 2-6 week lead time.
Developed as a challenge to prove that there is no reason why the 300blk platform needs to be expensive or difficult to get operational.
This is the SVERD. 
This upper comes out of the box with premium internals. Specifically, a Rosco 8.2” 1:7 twist barrel with a Rubber City Armory nitrided BCG using a C158 bolt, Sprinco springs, an adjustable gas key, and OCKS as standard!
Every upper is assembled with our extreme attention to detail. Grease is applied where needed, loctite is applied where needed, and all torque values are met!
So how did we reduce cost? Let us explain:
With this upper we set to reduce cost via cosmetics, careful parts selection and labor time reduction.
One example of this would be the gas block.
It is no secret we dislike set screw gas blocks. However, in order for us to keep high quality internals we had to use a set-screw gas block for exactly what they were meant to be: A low cost, fast and foolproof way of attaching a gas block to a barrel.
That said, in order for this to be the case, the barrel needs to be dimpled. Which of course in true Eitri’s Enhancements nature, we don’t skip out on processes, which means this barrel is dimpled to mate with the gas block.
This upper is ready to drop onto any ar15 complete lower with a simple initial gas adjustment to work with your lower and suppressor of choice!
