Posted on another forum too. Maybe some of you will enjoy this!
You may be asking, "why?!" I asked myself that question as well, honestly. I had a hard time answering it too. I guess it just fits in the 'unique' moderately useful rifle category. Some of you picky folks might call me out for calling this an AR10 and not an LR308, but for the sake of easy description, we're going to use AR10.
I have officially assembled a 7mm SAUM AR10. This whole thing started when I found an Aero M5 lower on sale for $98... I had X-Caliber cut a 24" barrel, using a KAK magnum bolt that I sent them for proper headspacing. While the barrel was in queue, I started gathering parts. I used a KAK magnum bolt carrier group, as stated earlier, and a KAK magnum stripped upper. They essentially just mill a larger ejection port. It's a little bit cheesy though, because they mill it AFTER anodizing. I really don't care, as it'll probably get rattle-canned somewhere down the line anyway. I put an adjustable gas block on it, as well as a jp heavy scs. It should be (relatively) tunable to ensure proper function. I threw on a luth-ar fixed stock because it was one of the few I could find with adjustable comb.
Why 7mm SAUM you ask? The SAUM line has piqued my interest for awhile, actually. And full disclosure, had I been able to find 300 SAUM brass, I'd probably have gone with that instead. I like the idea of having a semi-auto magnum... maybe it just sounds cooler than it really is, but oh well. It's definitely capable of taking any game in my local area, and if I want to shoot it long range, I can do that too. I think the 7mm is incredibly adaptable to whatever you want It's use to be. I have larue SR-25 mags that have a COAL limit of 2.870, and book COAL on 7mm SAUM is 2.825, so I have a little bit of room to play with for seating depth. Let me tell you, those little bastards ain't cheap! Consensus on accurate barrel life seems to be about 2000rds. I picked up 300 pcs of ADG 7mm SAUM brass, that will (hopefully) survive the life of the barrel. I figured 6 loadings should be ok, and I only need about 60% of them to last a 7th. Time will tell, I guess.
Dimensions are just shy of 46" and 12.5lb without suppressor, with suppressor, low-mid 50"s and about 14lbs. Way larger than I originally anticipated, but I wanted a 24" barrel to take advantage of the cartridge.
Let me know what you think. I only took one picture so far, so that's the one I put up with it, but if you want anything specific, don't be afraid to ask. And if you want a full build list, I can do that too. Might even be able to throw a price list together, if desired.
I'm not sure how to post a picture directly onto the thread, so I've just attached it, and I had to resize it super small to fit the max file size... Hopefully you can see it ok.
