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. (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.
