Mad Dog Weapons Systems has done some testing with the SFAR and Rogue. It appears the Rogue bolt will work in a standard AR barrel extension if you modify the lug on the extractor. It also works in the SFAR bolt carrier. Opens up rebarreling options significantly.

Outstanding. This is good info.

My SFAR will arrive next week. Looking at magazines, what's the general consensus on 20 vs 25rd PMAGs?

Ive even opted for light weight optics. A Vortex Spitfire 5x (10.3oz) with Venom RDS (1oz). Basic nylon sling. Going to be a light gun for sure. 9.4lbs unloaded. |

I’ve never had bad luck with my steel DPMS or magpul 20s, so I have stuck with them. Got a pack of magpul -5 limiters for their 10 round mags for elk hunting, making a 5 rd mag.
Once I get done playing around with this excellent, and heavy 3.5x10 mine will have a lighter LPV on. Be interesting to see how light the gun is then. Only other change is the brake is coming off, And a griffin linear is going on. Trigger is good enough so far. Attached File |

Brownell's sunk a lot of money into Retro, and I presume they dropped it b/c the ROI wasn't there. Would be difficult to convince them their analysis was wrong, might have better luck w/ @Mike_NDS |

Would be difficult to convince them their analysis was wrong, might have better luck w/ @Mike_NDS View Quote From what I remember there were two 308 retro mags. One was aluminum with a deep waffle pattern that was pretty close in appearance to original ArmaLite. Then there was a steel waffle mag made by E Lander. It was a fairly shallow waffle pattern. It looked okay but wasn't really a repro of the originals. |

Don’t know if they had issues, but we have mags that work and are cheap. I disliked magpul at first, but they just work. Mike, are you going to be doing anything for the SFAR? |

I think someone's already swapped POF BCG/bbl to the Ruger, & Ruger just announced a 6.5 Creed. If you want an off caliber, all you need is a bbl blank and sacrifice your Ruger bbl. |

Test fired my 20 inch SFAR in 308 today.
40 rounds fired on gas setting 3 and 2, both 100 percent reliable. I was using reloaded 308 previously chronographed around 100 fps slower than factory M80 ball. Ejection pattern was consistent around 2 o'clock. Recoil impulse was considerably lower than my expectations. The brass shows distinct marks for both ejectors, obviously there are 2 of them |

My idea of playing with buffer weights was only to see if the ejection pattern changes, and to test if reliability would change with a buffer weight increase. The ejector marks on the brass I'm not sure if I would worry about with the ammo I used. They were 150gr fmj hand loads that will clock around 2650 fps from a 1/12 twist M1A so by my data not as hot/fast as m80 ball. |

Never had issues with 5.56 ARs with pressure signs even having loaded alot of ammo that's published 5.56 data. Are you suggesting a buffer weight increase may reduce the ejector swipes I'm having? |

Took my 16” SFAR out for the first time today. Ran good but did not want to lock the bolt back with PPU 147gr. I’m told this a light load. It liked the Federal 308 150gr. Only put about 60 rounds through it on setting 2 and 3. Didn’t seem to make a difference. Shot moa with the Federal. Trigger is pretty good too. No brass damage at all. Love it so far.

Is there anything on the horizon as far as spare parts goes for the SFAR proprietary parts? If I could get a spare BCG, I would commit hard to this.
Right now I have just one, 16". I would get 2 or 3 more but I hate to own a rifle that I cannot work on/stock up spare parts for. |

The plane flew, admit you're wrong and get over it.

If you don’t have a SF yet, you are wrong.
Just got back from a 120 round range trip. Flawless, accurate and the recoil with my new linear comp was only a bit more than the excellent Ruger brake. I shot 20 with a bare muzzle, and the other 100 with the griffin comp. Really only a smidge more recoil bare, And the blast under cover was still rude, not as rude as the Ruger brake. The griffin did its job pushing the blast forward. A simple blast can would have done similar. Attached File Easy hits at 200, plenty of hits out to 420. I need a high bipod, or better, a good tripod. The steel goes way up there out to 600+ Great day for sure. I did try some DPMS steel mags, only the 10 rd would stay locked. The 20s would not stay in. Magpul 20s were flawless. Attached File Hit the pistol side too. Attached File |
