I just finished building this Aero M5. 18” barrel. Trijicon Tenmile 3-18x50. It’s meant as a bench rifle, although I have a Ferro Concepts padded slingster should I want to carry it. It’s a 12lb gun as you see it I’m going to shoot it for the first time this weekend. With the brake and all the pudge, I think it’ll be a soft shooter. Has an agb and 5.5oz rifle buffer. I’m going to be curious as to how the recoil is on these 8lb 308 rifles. Hopefully there’s some honest video out there soon. Administrative Results just released a video of a lightweight hK AR pattern 308. But I don’t remember the operating system. I believe it was a piston gun. He commented on the recoil being pretty stout. |

Got one on the way. 16" version. Pics and other info when I can.
|
|
|
Purchased the 16". Paid less than $1K at a local shop. Apparently the 20" sold the minute they put it on the wall.
It is surprisingly light. I have not weighed the rifle but subjectively it feels no heavier than my 6920. Trigger is light but the break it mushy. Only had a chance to shoot at a 25 yard indoor range. The felt recoil was less than expected - I assume it is thanks to the muzzle brake. Ran 60 rounds of Prvi through the rifle. It functioned 100% at gas setting #3. That being said, the muzzle brake has to go. I understand that shooting indoors was not the intended purpose of this rifle but I can imagine even on covered outdoor ranges the 'boomer' brake will be obnoxious. Next step is to spin on a flashhider, probably add a thicker recoil pad, and throw on an acog to try it out at a 300 yard range. In states where cans are legal or hog hunting is prevalent, I bet this rifle will shine. Here in Illinois, I am not exactly sure why I bought it. At least it's loud! |

I am here just thinking that converting it to 6.5 CM and it would make a nice hunting option.

Well, I stopped by the local fun store, and I now have one. I picked up the 16 inch barrel and I do plan on shooting it suppressed. I have been planning on building a Aero Precision M5 this winter, this just happened to derail that plan.
First things first. It seems really light in comparison to other AR10 pattern rifles. Now I am not saying it is earth shattering light, but oz = pounds when having to pack it around the side and over the top of a mountain. Ruger does deserve some credit for this. I have not seen or handled the other options (AR15 / 7.62x51 rifles) on the market, so take it for what that is worth. I will be removing the compensator on the rifle. I have the Comp for my Sandman S that is going to be on the end. Yeah the suppressor is adding on a ton of weight out front and I may be getting a lighter suppressor to live on it if I really like the rifle. It feels decent made, not cheap. It is nice that it has Magpul furniture on it so you can replace it if you want. My stock seems super tight on the buffer tube, I am not going to complain (one less rattle many AR pattern firearms have). The Trigger, WOW. They say it is supposed to be 4.5? I need to get a trigger scale on mine, because it sure doesn't feel 4.5 pounds it feels more like a 2.5 to 3ish. That may be me, so I need to get a scale on that to make sure I am not delusional. It is shorter and feels a lot shorter than the other AR10 pattern rifles. May have to do with a 16 inch barrel and moving the center of gravity back towards the shooter. Now I need to wait until this weekend to send a few rounds down range. Things I am going to put on it. 1-6 or 1-8 LPVO unsure about what optic I want to put on this. I am not a sniper and 400-600 is what I would say is my max range. I am sure it is very capable of 800 yards in someone else's hands just not mine right now, it is a 16 inch barrel. So I will keep my expectations reasonable. Suppressor it is going to have a sandman S on it for right now. Thoughts on putting on a light or bipod? |

Keep in mind, if hunting burglars, you're talking about setting off a .308 inside your house. Probably want that suppressor mounted 1st. Bipod - sure, w/ that can. Be tempting to see how you like it in the field w/ your new muzzle device & a blast can mounted, no bipod. |

From what I have gathered, the problem wasn't usually noticed until it was field stripped for cleaning and the bolt came out in two pieces. I would hardly call that grenading. In either case, if it fails, all you would need to do is purchase a RRA complete bolt carrier group. You could just purchase the bolt, but you would have to have the Bushmaster carrier machined to accept the larger diameter boat tail of the RRA bolt. I would hardly call that being screwed. Just fixing a broken gun. |

The pin you're seeing in the barrel extension is something Sig put into the 516 (and later rifles) for their Over the Beach testing. It holds down the extractor in the case that the barrel is obstructed, like full of water or something, so the extractor doesn't fail and rather pressure blows out the barrel.
Other OTB changes have been drain holes in the receiver extension, and a chamber designed to better support the case. The goal is being able to fire the rifle immediately after removing it from the water. I believe alot of these changes began with the 416. Originally Posted By ctfish15: Huh.

The GII also used some proprietary steel on the bolt. |

Mixed feelings here LOL...Barrett uses 4140... The cost in ammo, even if reloading! Neither do I, but not for the argument of ammo prices. I bought it to hunt with as a lightweight option that won't be a burden when slung. It's not for gun golf or rifle courses and neither for SHTF. I have an Armalite DEF10 for that if a 308 is needed over an AR15. When I decide to buy something, I do want the most for my money. While 4150 CHF and CL would be better, I rationalized over case use and decided to buy based on that alone. YMMV |

As the owner of AR10's and LR308's, I can never say that the controls would feel off or the guns themselves. Why? Because that was never the case with them. And as an owner of the SFAR too, besides the weight being less the only differences that feel off to me is that in an AR15 size like it's hard to not want to cram an AR15 magazine inside where an AR10 is supposed to go.

View Quote Guns themselves generally feel sort of off. At least to me. That's one of the things I liked so much about the G2 DPMS since the only thing really "off" was the size of the mag well. That and the distance to fully retract the charging handle. Deal breaker? Nope. But pretty cool that Ruger has been able to further tweak the concept. |

Does anyone know yet what barrel nut the SFAR uses? Will another brand of nut fit? BCM for example so that a MCMR can be installed? Is the height / tall-ness of the upper correct so it will line up with someone else's rail? I haven't measured anything but it looks like the gas block may have to be replaced with something else depending on which rail.

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. View Quote Does an AR-15 bolt fit in the carrier? Will the .308 bolt fit in an AR carrier? Does the Ruger carrier fit in an AR upper? Does an AR-15 carrier fit in the Ruger upper, or is it sloppy? |
