Contoured Blanks
Shilen's contoured AR-15 blanks are made with the gunsmith in mind. Using Shilen's match grade blanks and then
placing precision centers in each end before they are contoured gives us the ability to hold near-finished dimensions
while providing the gunsmith an opportunity to reduce the work required to produce a custom AR barrel for their customer.
Gas block dimensions are left +0.010" oversized to allow for final fit by the gunsmith.
Overall length is extended 0.750" on the breech end to also allow for the cutting of the thread shank and final chambering
by the gunsmith.
Pre-Threaded Blanks
These pre-threaded AR-15 blanks take the convenience of our contoured blank one step further by pre-cutting the
thread shank area in a CNC lathe. While the barrel is in the lathe a barrel extension is screwed on by hand to
verify final fit and left married to that individual barrel. Gas block dimensions are left +0.010" oversized to
allow for final fit and chambering by the gunsmith. (Barrel extension pin not included)
Drop-in Barrels
Want the custom AR-15 experience with Drop-In convenience? Well these barrels are up to the job.
Each barrel is machined using the same processes that have helped Shilen customers win endless competitions and
set so many World Records over the years. Using our pre-threaded blanks each barrel is assigned a bolt assembly
and then chambered to the correct headspace for THAT bolt. Gas-block shanks are machined to +- .001 for proper fit.
Each barrel is uniquely numbered to match with its' corresponding numbered bolt and the barrel extension is installed.
(Gas block and gas tube not included.) Customers can provide their bolt assembly for a discount or request that
multiple barrels be head-spaced to one bolt assembly.
