** The Geissele Border Patrol Rifle is California legal but may not depict actual CA compliant parts or modification. **
The Border Patrol Rifle is designed and made to be a fully-featured service rifle with an eye towards retaining mil-spec features where doing so had no negative impact on performance. This rifle is an excellent choice for those looking for a no-frills AR-15 that will offer years of reliable service. The barrel is a Geissele cold hammer-forged (CHF) that also features a chrome-lined bore. It is available in 11.5-, 14.5-, 16- or 18-inch lengths. The twist rate is 1:7 and it has a standard 5.56x45mm NATO chamber. The gas block of the carbine-, mid-, Geissele- or rifle-length gas system is made from precipitation-hardened 17-4 stainless steel. There is a retaining pin that holds the gas tube in place and the gas block is attached to the barrel by both pin and two set-screws. This redundancy in attachment ensures that the gas block is aligned and will forever stay that way unless deliberately removed.
