The SPR profile is our mid-weight AR-15 barrel, and is slightly heavier than our Recon profile barrels. These barrels are fully capable of MOA accuracy, if not better, when fed quality ammunition and have the specs to shoot SSA (and comparable) combat loaded ammunition.
Optional Shim Set: The best 5$ you will ever spend! These stainless steel shims guarantee you perfect and hassle free barrel nut / gas tube alignment within the correct torque specs every time. For more information on our shims and a step-by-step guide to their use check out our video HERE.
Optional Bolt: We check every bolt / barrel for proper headspace before they leave our shop. For more information on our bolts click HERE.
Optional Bolt Carrier: Carriers ship assembled and include the gas key, firing, retaining and cam pins. If you purchase a bolt and a carrier, we will assemble the complete carrier group for you before shipping. For more information on our carriers click HERE.
Optional Gas Block Pinning: Only available for low-pro gas blocks. We drill and ream precise holes in the barrel and gas block then press-fit a dowel pin through so that the block will never shift on the barrel. Most military and police weapons are pinned. For more information on pinning click HERE.

Shipping: In stock barrels (together with any additional parts ordered) usually ship within 5 - 10 business days from the date of purchase. Custom coating / bead-blasting and gas block pinning may delay shipping by a few days. We ship via UPS to addresses within the contiguous United States, and USPS Priority to Alaska and Hawaii.
Billing: Your credit card is charged for the full amount of your purchase at the time you place your order, not when your order ships.
