Experience unparalleled precision with the CONTOUR #4 BARREL by SHILEN.
The Contour #4 Barrel, available in Chrome Moly or Stainless Steel, embodies the dedication of master craftsmen in the firearms industry. While the skill of a stockmaker and the expertise of a machinist are crucial, the true accuracy of a firearm is determined by the barrel's construction.
Why Choose Shilen Barrels?
It is the intricate interior of the barrel—the lands and grooves—that play a pivotal role in the firearm's performance. A barrel can either enhance the shooting experience or merely serve as an aesthetic piece. True craftsmanship, not just price, defines the quality of a barrel.
Investing in a custom gun should not lead to compromises on barrel quality. Opting for a cheap, generic barrel undermines both your investment and your reputation as a gun builder. At Brownells UK, we stand by our commitment to quality. Our reputation, alongside yours, is at stake with every barrel blank we provide.
Manufacturing Excellence
Shilen barrels, whether made from chrome moly or stainless steel, are rifled with six lands and grooves using the Cold Forming process. This technique employs carbide dies meticulously crafted in Shilen’s facility, ensuring the highest standards of production.
- Finished barrels undergo air-gauge inspection with a sensitivity of .00005" (five-one-hundred-thousandths).
- Each barrel is also inspected using a 6X borescope.
- All barrels from .22 to .30 caliber maintain groove tolerances within .0005" and uniformity within .0003".
- No straightening is performed, and all barrels are fully stress-relieved.
- Stainless steel barrels are hand lapped at the factory.
Only barrels that pass rigorous specifications are available for trade. Any barrel deemed even slightly "suspect" is reprocessed and bored to a larger caliber, ensuring that quality and reputation remain uncompromised. Although these barrels may come at a slightly higher production cost, the superior quality and performance they deliver are unmatched.
