I am interested in this gun. In particular the 6.5CM. I would like an 18" option for that, but that is not offered.
Before I pull the trigger on one. - I have questions 1) is there rumor or expectation of any sort of Gen2 version ? And am I advised to await that? 2) initially there were some reliability issues. Have those been mitigated, and if so, how? Are we on a gen 1.2 now already? 3) accuracy reports so far appear acceptable - in the 1.5 MOA class or better - from what I can see of recent. Is that interpretation in error? 4) I will not be running a can. Considering replacing the factory break with a GAMMA .300 BO one, which are small at A2 FH dimensions. Has anyone done that? Results? 5) Is this a proprietary dimension barrel nut - or is it standard AR15 nut threads and dimensions? 6) for now, I assume there are no replacement BBL options, aside from Ruger? Does anyone else have the competency to make a barrel extension right, to do so? |

Does anyone else have the competency to make a barrel extension right, to do so? 6 - two routes: a) sacrifice the existing barrel, pull off the proprietary Ruger barrel extension, send w/ bolt & barrel blank to any number of barrel makers. I would expect Paladin Machine would do you a nice job; b) buy a barrel and BCG from POF, and drop it in the Ruger. No guarantees, as I don't think anyone's done that, but it looks as if that would work. As to your 18", just buy the 20" version & chop. Anyone w/ a lathe should be able to put a proper crown. You might have to enlarge the gas port a little, which would be an opportunity to replace the extra tall Ruger gas block. |

I'm getting sub moa accuracy from hand loads with my 308 16". But I also replaced the handguard, gas block, and shimmed the barrel to a thermal fit.
Still working on reliable function that also doesn't damage brass. All my loads so far, and even factory Federal Gold Medal, and PPU ball all damage the brass from the extractor and ejector. Only really light loads seem to be OK. Adding a heavier buffer has mitigated that a lot. For me there is a lot of potential but it isn't perfect out of the box for MY needs. Not all SFARs seem to have the brass damage problem |

Ordered. Was holding out to see of the WLVRN was going to be a winner, but I think will be waiting a while on that. And heck, at $905. I couldn't say no.

I finally took a 16" home.
My made in China scale says that it's lighter than advertised (6.69lbs vs 6.8 on the spec sheet). Trigger is awesome. Normally I SSAE everything, but I see no reason to replace this. Kudos to Ruger for getting that part right, where just about every other company continues to fail. Even top tier brands. The rest of the controls seem pretty normal for an AR, except for running the CH. That buffer spring is noticeably heavier, which makes sense. An upgraded CH makes more sense than ever on this rifle. The rail is just awful. Looks to be touching the gas block. The break is a meme part as well. It's probably already been covered here, but by my measurement, an 11" length rail would just cover the gas block. Maybe I missed it, but has anyone given the dimensions of the stock rail? If not, I can break out the calipers. |

At first glance the extractor looks like a standard AR-15 unit, but it's a bit longer. Width is the same.
It also has a half-moon cut near the spring and an opposing bump on the bolt that fits in the cut. This prevents a standard AR-15 extractor from being installed. The spine on the back of the hook is also a bit wider. It can be wider, because the barrel extension cuts are wider to accept the wider and longer lugs on the bolt. Even though the lugs are longer, the OAL of the bolt itself is the same as a standard AR-15. Tony  |

Tony, what is your opinion on these SF guns?
I like my Ruger 20”, but it seems “under built”. Particularly compared to my LF 308, or was the LF just over built? |

Quote HistoryOriginally Posted By DVCER: Tony, what is your opinion on these SF guns? The standard AR-10 bolt and barrel extension are built quite beefy for a .308. Enough so, they can take a pounding of 26 Nosler with no issues. Keep in mind, the more you neck the case down, the more bolt thrust you will get. I don't know if I would call it over-built, especially as a military design, but it can certainly take an ass-hammering with cartridges much larger than .308. At first glance the SFAR bolt and barrel extension look sketchy for a .308, but clearly, there is substantial engineering from Ruger that says otherwise. Ruger would not have made and sold it without a decent amount of safety built in for over-pressure rounds. However, it is a bit unnerving to see all the gas relief holes added in case something comes apart....kinda like they plan on it happening. With that said, I am not concerned at all with firing my .308 SFAR, but you sure as hell won't see me loading up over-pressure ammo, opening up the bolt for bigger shit, or any other Magnum mods for the SFAR. It is interesting that the steel they used for the bolt and extension (same steel for both) is nothing I have ever seen used for gun parts in the past. Tony |

Tony I'm curious the dimensions and steel grade used for the new ultra high P Sig Fury. I'm guessing similar? It will be curious what impact this new higher strength metalurgy will have on the gun world - could be exciting. Think .380 sized 9mm carry guns? Next gen-AR's? 60,000 PSI Grendel's and ARC's? 70,000 PSI 5.56? You can't really do that, you'll need to make new cartridges of new dimensions for Kaboom control, but still - could be a pretty interesting future. |

Has anyone ran the SFAR with a Non-Adjustable Gas block? Just curious about it. I know I'll probably need to swap my Ruger Gas Block out as one side of it is rubbing against the handguard. I'm probably going to be swapping the handguard out for something like G$ Mk16 15", but I also notice that I may need to adjust the Dust Cover accordingly as well.

I'm probably going to be swapping the handguard out for something like G$ Mk16 15", but I also notice that I may need to adjust the Dust Cover accordingly as well. If you do, you're going to need some sort of way to limit the gas. The gas port is huge. I don't have the exact size, but it's over .100 inch on the 16". And the buffer is a standard 3oz carbine buffer. I've switched to the riflespeed gas block and am currently running 7.6oz in an adjustable heavyweight 9mm buffer. If you do this, I would also suggest you get through the 200rd(or more) break in period before you do. Mine has slowly settled down in terms of recoil and damage to the brass over these first 200 rounds. I was seeing pressure signs on factory ammo and my very mild reloads but that has changed. I think whatever material they use must have some significant wear initially so they set the headspace as small as they can initially. As the bolt wears in, the headspace may grow slightly and the pressure settles down. Maybe, IDK. |

So, in hand - after shipping, tax, transfer New SFAR 20" 6.5 Creedmoor rifle. $950 That's just insane.
There's a LOT about this gun I like. Exxxceeept the gas-block/handguard. I don't mind either on their own - but holy shit - now I see why all the complaints, that gas block touches the F'ing handguard. And if doesn't actually, it sure as shit will under recoil! No wonder everyone has been bitching about that - that's a huge accuracy problem - especially since it won't even be consistent. How the holy F, did that get past development??? This is completely avoidable. I was planning on accuracy testing it tomorrow after work, but screw that, i need to fix this before I even bother wasting the ammo. Grr.. I have a PSA 13.5" handguard on a spare build kit (which is why I keep a spare build-kit: parts), but it really needs a 12" to clear. So... well shit, i see now why people talk about hitting these things with Dremel tools. My only concern there, is won't that mess up Ruger's legendary life-time warranty, if I Dremel their handguard? Hmm... but I might be able to adjust the PSA one to fit... though I see the ejector flap is now going to be a problem, since that pin integrates with the Ruger Handguard as the anti-rotation device. Gah! This is annoying. |

Naw, I see now, it's standard size - the Ruger HG is the only one that engages it in that way, others work fine. But sloppy sloppy on the gas block, it was bottomed out on the shoulder supposed to be off by a dollar bill), and wasn't even centered right- and no centering dimples on the barrel. So I pulled it out by that thickness and centered it. It still won't pass a dollar bill test level of clearance though between the top of the block and the handguard. Bleh, I'll dremel that open I guess, since now it's a PSA handguard and not Rugers I'm screwing with. But.. Bleh. Seriously Ruger, did the project manager have a kid or get the ""I'm just not happy" homecoming right there towards the end when picking handguard dimensions? |

The Midwest Industries MI-G4M fits the 16" perfectly. As per Hop's video, the 12.6" length allows you to adjust the gas using the standard tool that comes with it in the pistol grip.
https://www.opticsplanet.com/midwest-industries-mi-g4m-one-piece-free-float-ar-handguard.html?_iv_code=MWI-HZ-MIH1-MI-G4M12-625 Ruger's assembly team must be allowed to drink on the job. The factory hand guard screw was loose, and they were not installed with any locktite. One of the gas block set screws was loose. At least the barrel nut seemed about right. Easily forgivable if all the talented guys designed and built the barrel and bolt. I should get the optic in soon and we shall see. |

Wow.
6.5 Grendel 20" HBar  Same scope, same handguard - SFAR, with a decently thick 6.5CM barrel  Next question is: can it shoot? Which I'll be able to answer after I get the handguard adjusted internally for a little more clearance around the gas-block. Also, still with factory buffer, not sure if folks upsize those to H2's or not? The part that just kills me: Cheapest 6.5Grendel ammo you can buy: .95 cents a shot for FMJ - exclude shipping Cheapest brass cased 6.5 Creedmoor ammo you can buy: 0.89 cents a round for hunting ammo Thr elimination of $0.27/shot Russian Steel Grendel ammo is very impactful to the economics. Combined with SFAR and cheaper 6.5CM and just... wow. |

I read through the thread and didn't see anywhere if anyone posted bcg weight. Would someone who has one be able to weigh the bcg for me? curious as to reciprocating weight of bcg and buffer.

OK, For those interested, I pulled off the BBL nut to replace the handguard. The PSA Armorers wrench fits it perfectly. The Torque Wrench was set at 35 ft-lbs, and it came off easily before it popped. So the torque was something under 35. I suspect a good bit, under 35. I suspect, too much, under 35. Anyway, transferred over my PSA BBL nut for my PSA BBL guard, and took it to 40 ft-lb.
No wonder people get highly variable accuracy results. I guess we'll see, but under torqued BBL nuts IMHO aren't good to accuracy. And gas blocks butted up against the shoulder and inconsistently touching the handguard, would be another. TBH, for an ultra-light concept SFAR, the barrel on this is actually pretty heavy. I bet you could have a lot going with a Faxon GUNNER profile on this. But that's OK, it's still pretty light and for a 1000 yard gun (being a 20" 6.5CM and all), I like this profile. It's got some well thought out contouring to it, and I have high hopes for this barrel - we'll see! Also, the timing of the muzzle end perfectly aligns with a VG6 Gamma .300 BO Muzzle device. Which is the smallest break I can find for 6.5 dia guns, and is A2 dimensioned. It actually works pretty good, and is externally A2 dimensions. By eliminating the jam-nut and factory brake, and putting this on, with no jam, I took off almost 2 oz. more. We'll see, possible it might not take the recoil enough, so we'll find out. I think it will, and it works well on my Grendel's, but we'll see. Just a personal hang-up, but oversized muzzle devices irk me - give me that extra inch oversize in the form of more BBL please. |

All done.
Finally got it to pass dollar bill test. JFC RUGER - how did you get so much right, and blow that?  7# 5oz now With scope, 9# 2.6 oz - I can lighten that, but we'll start there. (Some technical notes more for my own record - put 32 in-lb on each of the 3 mount/rail screws. Muzzle device is thread degreased, blue locktitght, hand tight. It should carbon-lock the rest of the way with time. Put on a plastic pic' rail on bottom for the quick-detatch bipod.) Let's go shooting, shall we?    How impressed am I? I bought Ruger stock today (great Price / Earnings ratio) |

The Aero AR-10 build project from about 10 years ago. I really tried to be weight conscious. Probably should have gone with a 16" barrel. Even with a lightweight scope and mount, 10+ lbs unloaded.
 SFAR with MI rail, and slightly heavier scope and mount comes in about 1.25lbs lighter... And WAY cheaper / easier to put together. Well so far. Let's hope it runs. *should* have some time to shoot it this weekend.  |
