The video opens with friendly rivalry as the Classic Firearms crew debates which AR-15 is most accurate. Each person represents a different rifle. One shooter brings a personal LWRC rifle with a custom light bar, a T.REX Arms-style light setup, and a Modlite, noting it is mostly stock aside from the stock and a Geissele trigger. Another runs a Geissele Super Duty with a 14.5-inch pin-and-welded barrel in a “50 shades of FDE” configuration. A third uses a Griffin Armament-based 12.5-inch AR-15, described as a compact, “fun size” setup planned as the basis for a future build. The final rifle is an older URG-I style Daniel Defense Block II M4A1, highlighted as a proven, reliable combat-oriented platform now being brought into an accuracy-focused comparison.
The team explains the accuracy test format and how they will keep conditions consistent. All rifles use 1:7 twist barrels and share the same optic: a Leupold Mark 5HD 5-25x scope mounted on each gun in turn. This removes differences in optics, reticles, and magnification from the comparison. Four loads are used at 100 yards: Black Hills Mk 262, IMI Razor Core 77-grain, Federal Gold Medal .223 Remington, and PMC X-TAC 55-grain. On a single target, each ammo type is fired in five-shot groups at designated quadrants, allowing direct visual comparison of group sizes. The goal is to see how each AR-15 performs with match-grade ammunition versus standard 55-grain FMJ, and whether certain rifles show a clear preference for specific loads.
The Geissele Super Duty is evaluated first. With Black Hills Mk 262, the shooter notes two rounds through the same hole but an overall group that did not meet expectations, attributing one clear flyer to shooter error. IMI Razor Core 77-grain performs notably well, producing four tight impacts with one called flyer, estimated around sub-MOA accuracy. Federal Gold Medal .223 shows another cluster with two rounds in the same hole and an approximate 1 to 1.25 MOA group, excluding an earlier sight-in shot. With PMC X-TAC 55-grain, the rifle again prints two rounds through the same hole, and the full group is estimated around 1.5 to 2 MOA. The discussion emphasizes that the Super Duty shoots consistently, with IMI Razor Core standing out as the most impressive performer in this rifle.
The LWRC rifle’s target is reviewed next. With Black Hills Mk 262, four shots land in a tight cluster, while one round is clearly identified as shooter error. The group is described as sub-MOA when that pulled shot is discounted. IMI Razor Core again performs strongly, with three impacts stacked closely together and two additional shots still within a little over 1 MOA overall. The Federal Gold Medal .223 group is less impressive, with the shooter observing the group “walking” left as each shot was fired, resulting in a looser pattern and one obvious pulled round. Surprisingly, PMC X-TAC 55-grain produces a sub-2 MOA group, which is considered very good for standard 55-grain FMJ rather than an open-tip match bullet. The takeaway is that the LWRC handles a range of ammunition well, with particularly strong results from Mk 262 and IMI Razor Core.
Attention then shifts to the Griffin Armament-based 12.5-inch AR-15. The shooter notes that some early shots with Mk 262 may have been taken without fully taking advantage of the scope, and the resulting group is around 2 MOA. With IMI Razor Core, the 12.5-inch barrel produces one of its best showings, delivering a tight group that the team describes as “Primo” for a short barrel at 100 yards, with impacts close to stacking. A later group with the same load opens up slightly but remains solid for the barrel length. Performance with Federal Gold Medal is acceptable but less remarkable, and the group with PMC X-TAC 55-grain is the weakest, spreading noticeably. Even when discounting a single round, the 55-grain group still hovers around 2 MOA. Overall, the Griffin setup demonstrates that a 12.5-inch AR-15 can shoot well with quality match ammo, though it is more sensitive to ammunition choice than the longer-barreled rifles.
Finally, the Daniel Defense Block II M4A1 is reviewed. The rifle is framed as an older, combat-proven configuration now tested for precision. With Black Hills Mk 262, the rifle delivers one of the best groups of the day, with multiple shots stacked tightly and described as clearly sub-MOA, comparable or superior to the other rifles. IMI Razor Core again performs strongly, with three impacts touching and an overall tight cluster that reinforces the load’s consistency across platforms. The commentary emphasizes that the Daniel Defense setup “put down some good numbers,” showing that a reliability-focused, duty-style M4A1 can still produce excellent accuracy with quality ammunition. The segment underscores how both the rifle and the chosen match loads contribute to the strong performance, particularly with Mk 262 and IMI Razor Core.
