Description

The Resolute 300 is a semi-automatic rifle chambered in 6.5 Grendel with a 16.1" barrel and a 1:8" twist rate. The 6.5 Grendel cartridge is designed for effective range and retained energy past what standard .223/5.56 loads deliver. It's a reasonable choice if you want AR-platform ergonomics with better long-range performance. The synthetic stock keeps the package light, and the 10-round capacity is what comes standard.

At a hundred yards any time you're under three quarter MOA with an AR that's a really good number not a whole lot of guns or guys can hold that consistently.

Every 810 20 rounds or so I would have an extraction problem spent shell casings stove-piped against the bolt in the ejection port and then a live round stripped off of the magazine.

Confirmed with CMM G for this rifle there should only be one I know some guys do run to I put it back together with one o ring behind the extractor and it's been running 100% since.

If you had to pick one AR you could do a lot worse than this so it's been a lot of fun and I've really been glad that I got this particular ride.

The Resolute 300 draws consistent positive feedback on accuracy. Users frequently note that the 6.5 Grendel cartridge delivers at extended ranges for both target shooting and hunting, and the rifle's general construction supports that with reliable groups. Build quality is called solid across most reviews, with the rifle handling varied conditions without problems.

Ergonomics are well-regarded. Controls are described as intuitive, weight distribution feels balanced, and the rifle is comfortable over extended shooting sessions. Some components are noted as candidates for upgrades by more experienced shooters, but the platform supports modifications easily.

Price is a recurring criticism. The Resolute 300 costs more than some competing 6.5 Grendel builds, and several buyers have pointed out that budget-friendlier options exist in the same caliber. Overall sentiment leans positive, with accuracy and build quality carrying most of the weight in favorable reviews.
