Description
I was chasing a tight group at 600 yards with a .308 that wouldn’t punish my shoulder or my wallet on match-grade ammo. That’s when I started looking seriously at gas guns built like precision bolt actions. The Christensen CA-10 G2, .308 Win, 18″ SS Barrel, KeyMod CF Handguard, 20rd, Burnt Bronze is exactly that: a semi-auto rifle engineered from the ground up for sub-MOA accuracy, blending the reliability of an AR-10 platform with Christensen’s legendary barrel-making and attention to detail. It’s not just another black rifle; it’s a purpose-built precision instrument that fits out of the box.
Look, a lot of companies slap a fancy handguard on a generic upper and call it a precision AR. Christensen doesn’t play that game. The heart of this system is their proprietary, button-rifled, stainless steel barrel. I’ve put a few hundred rounds of various 168gr and 175gr match loads through it, and the consistency is what you’d expect from a company known for dominating the long-range bolt-action world. The 18-inch length is a sweet spot for .308 Winchester—it keeps the package maneuverable without giving up too much velocity, and it’s threaded 5/8-24 for your suppressor or muzzle device of choice. The entire package weighs in at a very manageable 8.9 pounds unloaded, which is light for a rifle this solid.
The carbon fiber KeyMod handguard isn’t just for looks, though the burnt bronze Cerakote over the aluminum receiver is certainly easy on the eyes. That handguard is incredibly stiff and light, and it stays cool to the touch. The KeyMod system gives you plenty of real estate for mounting a bipod, a sling mount, or a light, though I personally prefer M-LOK—your mileage may vary. The rifle uses a standard AR-10/SR-25 pattern, so you’ll find a huge aftermarket for triggers, grips, and stocks. The included 20-round Magpul PMAG is a trusted standard, and the rifle ran flawlessly with it and other SR-25 compatible magazines I tested.

Pros & Cons
The pros are significant: outstanding out-of-the-box accuracy potential, a lightweight and rigid carbon fiber forend, fantastic fit and finish, and Christensen’s customer service reputation backing it all up. It’s a rifle that feels premium. The cons? Well, at $2515.34, it’s an investment. The KeyMod attachment system, while functional, has largely been superseded by M-LOK in popularity. And like any precision semi-auto, it can be pickier about ammunition than a bolt gun, though I found it cycled everything from cheap M80 ball to Hornady ELD-M without a hiccup.
So who is this for? It’s for the shooter who wants one rifle to do double duty. Maybe you’re a hunter who wants a capable, quick-follow-up shot platform for open terrain, or a precision shooter who wants to compete in gas gun matches without building a custom rig from scratch. It’s for someone who appreciates that the small details—like the tension screw on the handguard to eliminate barrel contact—are already handled. This rifle is available at firearms-missouri.com for Missouri residents and nationwide.
Frequently Asked Questions
Q: Is the barrel truly free-floated?
A: Absolutely. The carbon fiber handguard attaches directly to the upper receiver via a proprietary locking collar and includes a tensioning screw to ensure a perfect, consistent free-float with zero contact points on the barrel.
Q: What kind of accuracy can I realistically expect?
A: Christensen guarantees sub-MOA with match-grade ammunition. From my testing with Federal Gold Medal Match 168gr, I was consistently seeing groups in the 0.6 – 0.8 MOA range from a bench rest, which is exceptional for a semi-auto.
Q: Is it compatible with my existing AR-10 parts?
A: Mostly, yes. It uses a standard DPMS-pattern upper/lower interface and SR-25 magazine pattern. The bolt carrier group is mil-spec dimensionally, and the lower parts kit is standard. The handguard and barrel nut system are proprietary to Christensen.
If you’re ready to step up from an off-the-rack AR-10 to a rifle where precision was the first priority, the Christensen CA-10 G2 deserves a close look.
