JP Enterprises JP15
I am in the middle of the third shooting season using the JP15 rifle for competition. It’s not very objective for a gun writer to say there is magic in a rifle, but in this one there is.
Let me tell you a couple of reasons why I think this way. We have a speed drill we practice often (mentioned earlier in this article): three targets at 5 yards and spaced three feet apart. The shooter starts with the gun on his shoulder and the barrel pointing at the ground. At the buzzer he fires two shots at each target. My best time is 1.3 seconds with the JP. I do this drill with every rifle I get in here to test, which is a lot of guns. I have never been able to beat that time.
During the 2012 Iron Man 3-Gun Match I engaged three sets of bonus targets at 550, 650 and 799 yards. The shooter was allowed up to five hits on each target. Most competitors brought a long range precision rifle for this stage, but I used the JP and cleaned all 15 bonus targets. I think I am the only competitor to do that with a main-match, competition .223 rifle.
Magic? You bet.
This rifle is extremely accurate and 100 percent dependable; both are qualities needed to help a shooter step up to the winner’s table. I am not anal enough to keep actual records of each round fired in every rifle I have, but I am well north of 15,000 rounds through this rifle without a gun-related hitch. When shooting ammo it likes, it still shoots half-MOA.
The heart of the system, as it is with any accurate rifle, is the barrel, which in this rifle is the JP Supermatch barrel. This button-rifled barrel is made from 416R stainless steel. This is a pre-hardened chromium stainless steel, which is engineered for use in precision match-grade rifle barrels and designed to work well with button rifling.
The barrel has a 1:8 twist rate and is air-gauged and cryogenically treated. It measures .88-inch at the muzzle where it meets the brake. The barrel has a wasp-waist that is fitted with a set of cooling fins hidden under the handguard to aid in rapid heat dissipation. The JP Thermal Dissipater between the gas block and receiver results in a 700 percent increase in surface area under the handguard. This keeps the accuracy-robbing heat from building up during sustained fire drills. That keeps the shooter’s hand cooler, but more importantly it enhances barrel life, too.
The chamber is .223 Wylde that will accept .223 Remington, as well as 5.56x45mm ammo. The barrel is fitted with a JP Compensator that is timed and blended to the barrel so well you can’t see the panty line.
My rifle has the JP Low Mass Operating System. This system uses a reduced weight bolt carrier and low mass buffer with a matched buffer spring. This speeds up the cycle rate and makes the rifle run smoother, which is an asset when doing rapid, aimed fire, particularly during some of the drills common to many 3-gun matches.
The rifle has the JP single-stage Fire Control trigger system with the low mass speed hammer for a faster lock time.
The receivers are 7075 mil-spec forged. The long, round, vented JP Modular Hand Guard is well suited for competition. It has a rail on top and two swivels. The side swivel is for a sling while the bottom is used for a bi-pod. The buttstock is the ACE ARFX skeletal, which I find perfect for 3-gun competition. There are a lot of reasons why I am not the top Tactical Optics class shooter in the country, but I guarantee my rifle is not one of them!
