Now that is has been in the wild for a few days how is the accuracy? I know the gunblast video said approx 1" at 100yd but curious what others are seeing. ESPECIALLY interested in how it handles cheaper 147-150gr stuff (PMC-Federal-PRIVI etc.). Thanks!

The longer buffer tube is normal on Armalite / KAC patterned guns. KAC, LMT , LaRue, Armalite all run that now. I bet the buffer is an H3. The upper and lower are from Matrix Aerospace . They make the 556 uppers and lowers for Ruger and the rails for them and Troy. I am interested to see what barrel nut thread they used, DPMS or Armalite. I think that gun would look great with KAC URX 3.1

Once I'm more familiar with the gun and decide which ammo it likes best, etc I'll play with buffers and see what happens. |

3.0oz? That is pretty light, but then it is a piston gun and not DI. I wonder what buffer weights POF uses.
Plus the return spring is also a variable. I know the KAC spring are different from the LMT and also the armalite. Congrats on the gun its a good looking toy! |

Another good thing about that lower is you can run uppers from Armalite, KAC , LMT and LaRue on it also.

Kult,
Do you have any experience with Matrix? I ask because it might be interesting to contact them about making a keymod forend for those of us who own Ruger piston guns. I'm also curious about the interchangeability of these new forends with the original Troy rails that were attached with the big roll pin instead of the two screws. Posted Via AR15.Com Mobile |

I spoke to them about stocking their receiver sets for my friends shop. I wouldn't bother since they are contracted by Ruger to make the stuff and the sales person I spoke to was of no help. They couldn't tell me the basics like what style barrel nut or if the upper was high or low rail. Best thing to do take do some measurements and take the barrel nut off and check every thing to see what will fit. If it's a DPMS high rail (KAC style) with DPMS threads then any Keymod rail that fits that upper type should work assuming there is enough room to clear the piston op rod , and if the barrel nut was different then it could be swapped or modified one made. I would try Ruger tech support first before the OEM.
I know this sounds weird, but every time I get a new gun that has some variation on a platform, I strip it down and sort out what is different. Quoted:

I'm going to assume that, right off the bat, no other rail out there will work on the SR-762. The rail/handguard used on the SR-556 is propriety to Ruger (it fits around their gas block and also contains the piston transfer rod) and there aren't any options for the 5.56. I will bet dollars to doughnuts that the SR-762 is the same deal.
With that said, it might be possible to find something that's got enough room underneath the top rail to contain the transfer rod and the spring that could be modified to work but the forend probably wouldn't be the proper length. The gas port location on the SR-556 is unique and I'm guessing the gas port location on the SR-762 is no different. Honestly, there are enough of these rifles (SR-556's anyway) out there that I'm surprised nobody is looking at making aftermarket rails, custom gas regulators, etc. Quoted:

It is hard to know unless someone takes the gun apart. I know what the diameter of the gas tube port is in the upper for DI guns, but it is probably different a piston gun.

I think the gun would work great as a SBR with the piston setup. It can always be setup to run DI by swapping the upper if the piston system is not to ones liking for precision work.

I like the ability to change gas settings while using a suppressor. I wonder how well it would group with a suppressor attached and the gas setting on single shot?

Where did you get the gun only a week or so after it was announced by Ruger?
Normally, they announce new guns just before they start shipping, so I was expecting it to be at least 4-6 weeks before any of these hit shelves, and even then, they will probably be scarce for a while. |

Is there any dimensional difference in the ArmaLite vs the DPMS firing pins? Can one be used in the other? What about bolts, extractors, etc?

I've been giving my intended use some thought and I think I'll set this gun up as more of a heavy patrol rifle as opposed to a DMR type. The idea is to keep weight to a minimum so I will not be adding any sort of bipod, etc.
I will keep the factory Ruger stock and recoil parts and may or may not replace a few small parts like the BUIS to save an ounce or two. Along these lines, I'll leave the Aimpoint in place and add a 3x detachable magnifier for those rare times the rifle gets used beyond 200 yards. If the idea proves to have merit I'll probably replace the Aimpoint PRO with a T-1 to shave off a few more ounces. As pictured above with no sling, the Aimpoint and a full mag the gun is 10.8 pounds. I'll update a bit more once I have the magnifier mounted and a sling attached. |

How is the trigger pull, any idea of weight?
Round count and any malfunctions? Thanks for all the great info btw! Edit, just realized your in AZ too, what town you live in? |

Although the gas blocks and forends certainly appear to be the same and they are the same length, they are not identical. The SR-762 is slightly taller than that of the SR-556.
The SR-762's gas block measures 1.832" tall while the SR-556 measures 1.721. Both blocks were measured from the bottom of the block to the area just behind the gas regulator seat. Posted Via AR15.Com Mobile |

Posted Via AR15.Com Mobile I believe the only rifle cross-compatible with an Armalite BCG is LaRue. I haven't tried that, swapping bolts, but I don't think it would work. The big guns are creatures unto themselves, for the most part… some parts interchange, but most of the critical ones do not. ETA: JP makes a "high pressure" bolt that has a smaller firing pin hole, too, along with a redesigned ejector. I haven't seen one of those, either, or know if they would fit an SR rifle. |

Let's not forget the recent debacle with the Magpul Masada/Bushmaster ACR. That gun was paraded before our eyes as the ultimate defensive firearm. It was touted as a mature design with incredible modular capabilities with an abundance of conversion parts at a price that was going to be well within most budgets. Here we are four or so years later and none of the promises have been fulfilled.
I wonder how many companies have used the "announce & tease" method as a way to test a product's consumer interest. Announce and advertise it as coming soon. If customers and dealers start calling asking for delivery dates, the firearm gets produced. If nobody calls, or customer inquiries are minimal, the item is cancelled. Quoted:

Kentucky Gun Co posted a new video about the rifle and doing a small torture test. Not too thrilled about the 8-9LB trigger. Mine should be in this Tuesday, we'll see how it compares.

I just watched the video. I had my fingers crossed but to no avail. I guess I don't know why he thought the rifle would work once the upper was full of crud. You can actually hear the bolt carrier rasping back and forth in there after he pulls it out of the puddle!
Regarding the trigger; mine is actually quite usable as-is. It had a little catch about halfway through when I first took the rifle out of the box but some dry firing and some Brian Enos Slide Glide cleaned it right up. I haven't put a gauge on it but it isn't anything worse than most AR's out there. Also, the internals are standard AR so a Geissele or a CMC or any suitable match trigger should really do the trick if you're not happy with the factory pull. |

I wonder if they clean the gun after this or just sell it as is?
