Description
I remember the first time I shouldered a Knights SR-25. It wasn’t this exact model, but the lineage was clear—a purpose-built, semi-auto precision rifle that bridges the gap between a battle carbine and a dedicated marksman’s tool. The Knights SR-25 Enhanced Combat Carbine with 16″ Dimpled Barrel is the evolution of that legacy. It’s a semi-automatic, direct impingement 7.62x51mm NATO/.308 Winchester platform built on the SR-25 pattern, featuring a 16-inch cold hammer-forged barrel with a unique dimpled profile for weight reduction and heat dissipation. This is a rifle designed for the shooter who demands reliability and extended-range capability in a more maneuverable package, and it ships to Missouri and compliant US states.
Look, the SR-25 isn’t just another AR-10. The pedigree matters. This Enhanced Combat Carbine (ECC) variant takes the proven core and optimizes it for dynamic use. That 16-inch dimpled barrel is the star of the show. It shaves crucial ounces off the front end compared to a standard heavy contour, making the rifle swing and transition noticeably faster. The dimpling also increases surface area, which helps manage barrel heat during sustained fire. I’ve put a few hundred rounds of mixed M80 ball and match-grade .308 through similar setups, and the consistency is what you pay for—the cold hammer-forged process and chrome-lined bore are built for a long, accurate life.
The upper and lower receivers are machined from 7075-T6 aluminum, and the fit is exceptional. You get that solid, single-piece feel Knights is known for. It uses a standard SR-25 pattern, which means compatibility with a wide range of aftermarket parts is good, but not always universal. For example, the rifle ships with Knights’ own URX 4 handguard, a rock-solid mounting platform that’s compatible with a huge array of M-LOK accessories. The ambidextrous controls, including the safety selector and magazine release, are a thoughtful touch for left-handed shooters or anyone running drills from unconventional positions. The whole system is drop-in ready with mil-spec triggers and buffer components, so you can start running it the day it clears your FFL.
Here’s the thing—at just over five grand, this is a serious investment. The price point of $5141.98 puts it in a realm where expectations are sky-high. You’re paying for materials, machining tolerances, and a reputation forged in the most demanding environments. Is it worth it? For a civilian, that’s a personal calculus. The rifle weighs in at approximately 8.9 pounds unloaded, which is respectable for a .308 platform. The 16-inch barrel keeps the overall length down for vehicle or home defense use, while still providing excellent terminal ballistics with the right ammunition. Magazine capacity will typically be 20 rounds, using SR-25/KAC or compatible PMAGs.

Pros: Unmatched build quality and reliability. The dimpled barrel offers a fantastic balance of weight and rigidity. Ambidextrous controls are a huge operational benefit. The URX 4 handguard is one of the best in the business. It’s a legacy system with proven performance.
Cons: The cost is a significant barrier. It’s a premium-priced tool. Proprietary parts can be more expensive and harder to find than standard AR-10 components. The 16-inch barrel sacrifices some velocity compared to an 18 or 20-inch model for long-range precision work.
So who is this rifle for? It’s for the shooter who views their gear as a long-term investment and refuses to compromise on reliability. It’s for the tactical competitor who needs a .308 that can keep up in multi-gun matches. It’s for the serious civilian who wants one of the most proven semi-auto .308 platforms ever made, available at firearms-missouri.com for Missouri residents and nationwide. This isn’t a plinker; it’s a professional-grade instrument.
Frequently Asked Questions
Q: Is this compatible with my DPMS pattern AR-10 parts and magazines?
A: Not directly. The Knights SR-25 uses its own pattern for certain components. While some parts may interchange, you should assume magazines, bolts, and some small parts are SR-25 specific. It’s best to stick with Knights-branded or confirmed-compatible parts like KAC or some Magpul SR-25 PMAGs.
Q: What’s the real-world accuracy potential with that 16-inch barrel?
A: With quality match-grade ammunition, you can reasonably expect 1 to 1.5 MOA accuracy, potentially better in the hands of a skilled shooter. The barrel is the heart of the system, and Knights’ cold hammer-forging process yields incredibly consistent bores. The dimpling doesn’t hinder accuracy; it manages weight and heat.
Q: Does it come with iron sights or an optics mounting system?
A: It typically does not include iron sights. The upper receiver has a flat top Picatinny rail for mounting your preferred optic. The URX 4 handguard uses M-LOK for attaching forward grips, lights, and lasers. You’ll need to budget for an optic, a sling, and likely a light to make the rifle complete.
If the idea of owning a piece of that legacy, built to a standard that shrugs off hard use, speaks to you, then this Knights SR-25 ECC deserves your full consideration. Check its availability with us.
