    What AR15 cartridge is a worthwhile step up from 5.56?

    Make one a Franken14. 2500 fps with M118 LRs. With the Salmon River Solutions 5 port Ti brake reduced recoil, shooting prone at rattle battle pace is a lot more fun compared to full blown standard 14.

    What can cause accuracy to fall apart at 700 yards?

    Button or cut? Do you know the twist tolerance of either one? One time we had one button AR barrel stamped 8T, but it would stabilize any 80 trainer. At 600 it was 8 ring to 8 ring for normal distribution. We handed the shooter another rifle, he shot 200-11X. We surmised the 8T he had maybe...

The old brake cylinder hone in the tailstock does a good in polishing the bored out tube. The one with pressed in brass plug is the same on...

    BUIS on AR15

    Here is the 16 inch carbine I built for an LT at Benning. He wanted this configuration, folding front (also the gas block like the standard M16 a frame) and rear sight bases. No idea where he sourced the parts. But, I like them. Better built than what I normally see. What a pain to modify the...

    Does Bartlein, Kreiger, and Proof carry as much weight in the AR world as they do in precision rifle bolt-action guns?

    Frank posted this score sheet in another thread before. 3rd match of the 2023 CMP Cup. Frank donated the Bartlein blank, I spun the 20 inch service rifle barrel for a Texas Junior. She won the match over some of the best in the business.
