Bushmaster AR-15 Rifle

Rock River makes one of the best Bushmaster AR-15 Rifle you can buy in my opinion. Rock River's reputation for producing a high quality AR-15 Rifle is absolutely solid. This was Garrett's personal AR-15 Rifle, and he had it set up to his liking. It has a 16" barrel and a Trijicon ACOG for a sighting system. The other significant aspect of this AR was the addition of a JP trigger assembly. The JP trigger lightens the trigger pull, and it was absolutely glass-like in its release. The rifle also had a Fab Defense broomstick bipod up front, and a UBR collapsable stock. Garrett had installed an Ergo grip to the pistol grip. I liked it. It is a little more hand-filling and gives the shooter a very positive grip.


The AR-15 Rifle platform has been around now for about 50 years. The fully automatic Colts have been the primary battle rifle of the U.S. military since the 1960s. They have made their way into the arsenals of police SWAT teams nationwide, and, increasingly, they are being carried in the patrol cars of line police officers. And, over the years, they have been improved to give better reliability and overall performance. And, as I write this review, and as you read it, there are thousands of U.S. troops in faraway lands fighting our nation's battles with this weapon. You just can't help but to acknowledge the comfort level that goes with shooting this rifle. It is familiar to us with respect to its layout and operation, and it has a long track record.

No surprise then that the Rock River delivered as expected. It was reliable in operation and accurate. Using the 4X Trijicon ACOG, I was able to print 1-inch groups at 100 yards using PMC full metal jacket ammo. A Rock River AR-15 is not the cheapest AR on the market. Nor is it the most expensive. But this is a quality rifle, and you get what you pay for.

My shooting career began in earnest on KD-range 5 of Camp Pendleton, CA, with the M16A2. Ever since then, my first choice in assault rifles has been a variation of the M16, whether it be an A4, or an M4. Other military rifles such as the SA-80 or galeil offer some interesting features, but don’t hold a flame to the overall design of the modern M4. In the civilian world, the Bushmaster AR-15, and M4 have so many variations that some of them are completely unrecognizable from Colt’s original design until the bolt is locked to the rear. Most design modifications for the AR-15/M4 platform are relatively minor, and carry large, sometimes ridiculous, price tags. When it comes to military application, these price tags become major issues, because, let’s face it, who’s going to win a firefight- one Marine/soldier with a decked out, highspeed/ low-drag M4, or four Marines with decent M4s that cost collectively what the single customized rifle cost?
