Does anyone have one of these. I bought a used one, bottom end is Armalite AR10 with green furniture. Top end is stamped 300 RSAUM just above the Armalite markings and 7.62 mm marking. No forward assist, fiberglass free floating fore end with short quad rail on front. Magazine has Armalite floor plate and what looks like a standard follower.

Is it an Armalite top end, or 3rd party??

Thanks,
Bear

SOC really likes his. Felt it gave him near 300 Winchester Mag performance, and a superior distance profile. His threads will tell you more. Try searching by SOC as well, as 300 RSAUM.

Very nice rifle I here a lot of good things about them. I would think that's a keeper.

I made it to the range yesterday, only loaded ammo I could find was Nosler Custom. Shot 12 rounds total while adjusting scope, wish all scopes use 1/4 MOA adjustments. Trigger was terrible, long and gritty, 10X maximum scope power, 3 shot group inside 1". I ordered a Timney 4# trigger and 3 Armalite 15 round magazines. Armalite has no parts for the Ultra Mag. Tim Rooker referred me to SOC's post on magazine modifications, SOC indicated the 15 round magazine can make a good 10 round RSAUM magazine with mods. Also shot lightweight .308 Carbine, worked perfectly recoil about the same between two rifles. I expect much better groups with the new trigger. Usually do 5 shot groups, but at $3 a round having wasted 12 getting zeroed, and with poor trigger decided 3 was OK. Either should be great hog guns. Really like the Ultra Mag.
