Even $60 bolt carrier groups have smooth bearing surfaces. That’s just sloppy machining, it wouldn’t cost more to do it right. |

Continue to really enjoy mine.
The acog 110 is a nice compliment to the rifle. I ditched the brake and mounted a Wilson combat flash hider. I also dropped the gas setting to '2' after the first 60 rounds. Rifle was totally reliable for another 100 rounds on that setting. I have been getting sub MOA groups at 100 yards with Hornady ammo and I find the recoil to be more than manageable. She's a keeper assuming the bolt doesn't split in half ha! |

Quote HistoryOriginally Posted By Melvin_Johnson: So there's no free lunch. I assume a sub-eight pound 308 will kick like a sub-eight pound 308. Not that it will necessarily be unpleasant but it no doubt won't handle like a 223, either. That's a guess since I haven't fired the SFAR yet. Externally the gun is very familiar. Effort needed to work the charging handle is more but otherwise everything feels correct. Distance to selector, bolt catch, mag release all feel right. The distance the charging handle travels also feels right. Most 308 pattern guns are sort of "off" with everything kind of being 5% or 10% out of whack. Not so here. Balance is good. But that's naked and empty. I assume 20 rounds of 168 BTHP will offset the general AR15 feel. But it still should feel more or less correct. The bolt and barrel extension is where the "magic" happens. Ruger claims to be using some kind of hot rod material in these parts. Lug geometry is also supposed to be improved. Too bad the Armalite crew didn't have modern stress analysis tools. Anyway, here are a few pics of the bolt and carrier. https://uploads.tapatalk-cdn.com/20220927/852f127bd39f49b5d58dcbf4c8c6d291.jpg https://uploads.tapatalk-cdn.com/20220927/30b3084e25108d41a57e87b8caf67bf8.jpg https://uploads.tapatalk-cdn.com/20220927/d729c15578ce3bbe9d951c652d5e93ac.jpg https://uploads.tapatalk-cdn.com/20220927/27b2a4d2fa4cf059da9c50c2985468e4.jpg https://uploads.tapatalk-cdn.com/20220927/e8c914c59e865028b4abebeccf96f62f.jpg https://uploads.tapatalk-cdn.com/20220927/c0a8eff479727ca33303c7e397a051ea.jpg https://uploads.tapatalk-cdn.com/20220927/d207a80072971c4077cad86bad88117c.jpg My opinion may change after I actually shoot this thing but presently I think it is one of the coolest things Ruger has done in a long time. Something like this in 6.5 Creedmoor with a Proof barrel would be pretty much as modern as the modern sporting rifle can get. Perhaps we can call that a "micro sand cutter bolt carrier". It's a performance enhancer. |

 This appears to not fall in line with engineering recommendations for minimum screw flange edge margin (google it). Not saying they didn't do their homework, just saying it's worth monitoring since they dropped the second screw normally attaching gas keys. |

I like the adjustable gasblock features and would not want to lose those. Yeah the guys @ 7mmvalkyrie have already made a 27RPR barrel: https://mdws.forumchitchat.com/post/show_single_post?pid=1333502892&postcount=29&forum=557730 It looks like any competent barrel maker (if willing) could spin up a 6.5CM or similar given access to the factory barrel extension. The only thing I'd be concerned about is whether the firing pin is "high pressure" and plays nicely with 6.5CM, .260Rem, etc. As FN (among many others) found out, you can't just drop a 6.5CM barrel into a rifle using a .308 bolt. |

If someone has already conducted a caliber conversion, is it safe to say that there is definitive cross compatibility with AR 15 handguards? Just curious because I found one of these new SFARs locally and I can get into it for under $1k. The rail that comes on the rifle itself just doesn't do it for me as it has limited 12 o'clock rail space and the pattern of it is very unappealing to me. The gun itself is rather light when I compared it to a Stag Arms AR and the Sig Tread, both in 7.62, and both seem like very well built items. Going the SFAR route, for me, would seem practical in the sense that I have extra AR 15 rails laying around that I would swap on to the SFAR so long as they will work. Anyone have some details or opinions that they could share to confirm this?

When it happened to me the guns weren't in my custody, in one case I bought a barrel sight unseen and it came rusty. It's mostly theoretically a detriment to accuracy, the recipe for a sub minute chrome lined barrel is known, if you want to pay for it. My first ten shot .75" group that I fired off a rolled up jacket was with a chrome lined barrel. |

Not arguing against nitride as it’s a damn fine treatment, but the quality of the barrel is going to determine accuracy more than the bore treatment. I’ve seen plenty of sub MOA chrome barrels and plenty of nitride duds. FN for instance was held to a .5 MOA average for their FBI contract across 5 test rifles for 2,000 rounds each and succeeded. This was with chrome lined barrels. |

Has anyone shot their SFAR with iron sights?
I threw on a set of Magpul MBUS yesterday and zeroed at 50 y. I had to darn near (3 clicks from bottom) bottom out the front sight to do so. The rear took about 16 clicks right windage. Rifle shoots good though. Portuguese 79-48 all landed in nice tight 5 shot groups. Guess I'm curious if mine is the exception or if Ruger and Magpul aren't gonna jive. |

The debate of Nitride vs Chrome lined was beat to death several years ago. Done correctly, Nitride is a very good treatment. As far as rust, Nitride protects BOTH the bore and exterior of a barrel. Accuracy wise, given equal quality of the barrel machining, Nitride treatment is arguably more likely to keep precision machining intact, whereas chrome adds material which has the potential to create inconsistencies that did not exist prior to the addition of chrome. Chrome has benefits for machine gun barrels but I read and experienced enough evidence to decide that there are more advantages to Nitride treatment on both bore and exterior of a barrel for most non-machine gun usage. |

After only hunting/shooting bolt .308, I'm ready to get .308 semi, and was just about to get the very imperfect but proven Sig 716i when the SFAR came out.
Wow - I love the all of the features/price of the 20” SFAR - and would run it as-is w/a scope (TBD) and offset magpul pro irons - no muzzle brake and no can. Great elk/bear/hog gun - good in the bush, maybe great for distance. Anyone have experience w/magpul pro offset irons on the SFAR 20" pic rail? Has anyone shot the SFAR without the muzzle brake and without a can? Curious what the recoil/noise is like w/no brake/can. Has anyone mag dumped / sent a few hundred rounds down range yet? (I know, I know - that's expensive, but some of you have stashes of .308 lol and aren't afraid to burn thru it). I'm seeing mixed signals on the quality of the SFAR BCG - and my biggest concern with a small frame .308 is can it handle .308 pressure (chamber/BCG). If Ruger cut corners I would rather not be in the guinea pig test group ... New to this forum - the website is a little overwhelming lol but thanks in advance for any help. |

I just got home from shooting my 16" SFAR. It is outfitted with the stock muzzle brake and Magpul offset iron backup sights. I topped it with a Monstrum 1-6x24 Spectre LPVO.
It took 7 rounds to sight in the scope and 20 for the irons. Out of the box the Magpul sights were almost 8" low and 6" right at 100 yards. This was why so many rounds to sight them in. Once sighted in the sights functioned just like AR open sights. The rifle itself was very accurate even with Tula steel case 150 gr FMJ. The muzzle brake works very well taming recoil. Ruger engineering did well. The brake is as loud as the reviews say it is and it does throw a bit of fire to the sides as well. We put 100 rounds through it without a single issue of any kind. At about 80 rounds I did turn the gas down to setting 2 from the factory shipped 3. It initially threw brass like an HK91 but once broken in and turned down it consistently throws brass about 6 feet in a neat pile. Love this rifle more than any other 308 semi I have owned.

Two things from my initial outing.
Read the manual. It's a jam nut not a one piece muzzle break. Oh well, came off just fine. Replaced with a muzzle break to interface with my YHM R9 (see my thread in silencer forum). The rear face of my ejected brass has little sharp brass tits. I think the brass is flowing into the ejector housing, and encountering some kind of sharp edge during rotation before extraction. I'm not exactly sure, never seen this before. I fired maybe 40 rounds. This was ammo inc 150 gr from Palmetto. I can get a picture sometime and post it. |

It might be the nature of the SFAR, my 16" sure seems over gassed as well. On my initial range outing the first 3 rounds were fired with the gas block on the '3' setting as Ruger specified, those rounds ejected at 1 o'clock and landed somewhere in the next time zone. I immediately dropped the gas to the '2' setting which did help somewhat; even on the '1' setting without a suppressor I can get the rifle to cycle 4 out of 5 rounds, it's just inconsistent enough I bumped it back up to '2'. Ruger says in the manual that the buffer and spring are 'proprietary'; really? It's just a standard 3 ounce carbine buffer. I've played around with an H and then an H2 buffer; the H2 does mitigate the recoil and ejection is a consistent 4 o'clock. I've got 340 rounds through it as of yesterday. |

Quote HistoryOriginally Posted By ctfish15: https://imgur.com/a/8vPtCPn Album at link. I photographed a few different pieces of brass. Ammo inc, zsr headstamp https://i.imgur.com/c1DmRbl.jpeg Edit This is apparently called "case head swipe". Learn something new every day https://www.snipershide.com/shooting/threads/case-head-swipe-from-a-308-jp-lrp07-help-please.190669/ FWIW... I am not a fan of Turkish ammo... the older ZQI 308 ( sold at Walmart for cheap ) was the worst "grouping" ammo I have ever used, it would make shotgun patterns rather then groups. Did you happen to try any other 308 ammo ? Did any other brand cases have the same mess on the case head ? |

I did read the manual that says the setting is read from the shooters right. So at least I know what setting I'm on ... If the buffer is really a carbine buffer that would be easy to swap to H etc. I'm also going to see about a different charging handle (gas mitigation), since I think I read it's the exact same AR15 pattern. |

I'm really puzzled if it's a stock carbine buffer & standard length collapsible stock buffer tube.

As shipped, it's a standard carbine buffer, weighs 3 ounces. The receiver extension/buffer tube on the SFAR is longer than a standard length carbine tube. |
