‘Professional Grade’ Carbine In .308 Winchester

Sometimes marketers come up with impressive sounding descriptions for products, like “professional grade.” That term implies, of course, that people who need to depend on that item for their livelihood can do so because the item is that kind of quality.

Sometimes that it truthful advertising, other times it’s not. But Rock River Arms clearly means that this really is professional grade when they refer to a carbine that they released in .308 Winchester. Why do I say that? Because the company has a history of making AR-15s and AR-10s for hunting, competitive shooting, and law enforcement, and that last group, especially, are people who aren’t going to keep buying a gun that doesn’t do the job just because of the marketing.

The carbine that we’re talking about today is their BTR Operator ETR. Jeremiah Knupp gives us details:

The BT3 Operator ETR is a big brother to Rock River’s LAR-15 Operator ETR. Like the 5.56 NATO version, it has a 16″ chrome-lined barrel and low-profile gas block, which sits inside a 13″ lightweight free-floating handguard with a Picatinny rail section on the top and M-Lok slots on the sides and bottom. Included are a M-Lok five-slot Picatinny rail section and QD swivel port. The charging handle is extended. Furniture is a Hogue beavertail pistol grip and a telescoping, six-position RRA NSP CAR buttstock. The trigger is Rock River’s two-stage ultra match unit.  

Chambered for .308 Win., the BT3 Operator ETR uses Rock River’s billet-machined BT3 upper and lower receivers. 

Knupp notes that the MSRP on this firearm is $1,970 and comes with a “1.5-m.o.a. accuracy guarantee for a three-shot group at 100 yards.”

Sounds like Rock River Arms feels pretty confident that this firearm will shoot accurately and consistently for you, so, if you’re in the market for an AR-platform firearm, the Rock River Arms BTR Operator ETR may be one to consider.
