Again I respect that you folks want to shoot structured competition, but that is not for me. As for spotting splash, setup of targets, etc. all true, but I guarantee you that I can spot splash on the berm at about 900 yds. Took me a fair amount of ammo to walk my shots out there. Distances.........for some reason my rangefinder really gets spotty (to not returning any information) on that range beyond 250-300 yds.
If you can arrange the Puuloa range for AR based firearms that would be great, I would think that there are a bunch of us here who would take you up on that. Keep in mind though that some of our stuff might not be strictly US issue, so I'd rather not have a bunch of guys getting upset if I bring out a REPR (AR10 based, side charging handle, muzzle brake, etc.) or a SR9TC (HK91 based, non-US, etc.). I know there was quite a broohaha a while back about some guys shooting out there with non US based cartridges.
80% of the rifles shot at Puuloa competitions are AR based.
Muzzle brakes are specifically prohibited by NRA rules.Only M1A/M14, M16 "birdcage" or A2 styles are allowed.
Per the NRA High Power Rules
3.16.1 Compensators and Muzzle Brakes - The use of compensators or muzzle brakes is prohibited. An extension tube that has been installed on the muzzle of a rifle to extend the sight radius shall not be considered a “muzzle brake.” The extension tube must have an interior diameter of .5 inches or greater and may have 1/4” x 1” slots cut at 12 and 6 o’clock to remove cleaning patches. Threaded holes along the top of this tube for the installation of sight bases will be allowed.

The front and rear sights must be the standard or National Match design, but may vary in dimensions of rear sight aperture and front sight blade. The rear sight aperture may be hooded. The internal parts of the rifle may be specially fitted and include alterations that will improve the functioning and accuracy of the arm, provided such alterations in no way interfere with the proper functioning of the safety devices as manufactured.
