ArmaLite AR103GN13 AR-10 .308 Win 25+1 – MBA-1 Stock

Description

This ArmaLite AR103GN13 AR-10 .308 Win 25+1 with MBA-1 Stock is a purpose-built rifle that doesn’t waste time on frills. Chambered in .308 Winchester / 7.62 NATO, it’s set up for practical rifle and 3-gun competition right out of the box. The adjustable Luth-AR MBA-1 buttstock and Timney single-stage trigger give you the control you need for fast, repeatable shots, and the ambidextrous controls make it work for lefties and righties alike. If you need a .308 that runs hard and hits where you aim, this one’s worth a look.

Key Features

• Adjustable Luth-AR MBA-1 Buttstock — why it matters: You can dial in length of pull and cheek height for a solid weld, which keeps your shots consistent from the first round to the last.
• Timney Single-Stage Trigger — why it matters: A clean, crisp break with no creep means you won’t flinch or pull your shot, giving you the precision this .308 demands.
• Ambidextrous Controls — why it matters: Whether you’re shooting lefty or righty, the safety and mag release work the same way, so you don’t have to fumble under pressure.
• Match-Grade Barrel — why it matters: It’s built to hold tight groups at distance, which is what you need when you’re ringing steel or punching paper at 500 yards.
• MIL-SPEC 7075-T6 Aluminum Receivers — why it matters: This isn’t pot metal; it’s the same stuff used in military rifles, so it’ll take a beating and keep running.

Who It’s For

This rifle is for the shooter who competes in 3-gun or practical rifle matches and wants a .308 that can keep up. It’s also for the rancher or rural worker who needs a hard-hitting rifle for predator control or long-range varmint duty. If you’re the type who values reliability over flash, this fits.

Pros & Cons

• Pro: The Timney trigger breaks clean at around 3.5 pounds, which gives you a predictable pull every time.
• Pro: Ambidextrous controls make it easy to shoot from either shoulder, which is handy when you’re working around vehicles or obstacles.
• Con: The Luth-AR stock is adjustable but adds some weight compared to a fixed stock; if you’re humping it all day, you’ll notice.
