Ruger SFAR .308, topped with the Primary Arms SLx 3x MicroPrism. It’s hard to really wrap your head around just what the SFAR is. It’s an AR-15… It’s the size of an AR-15, and it’s the weight of an AR-15. But it’s not really an AR-15, because it’s chambered in .308. And as everyone knows, that would make this an AR-10. But it’s not an AR-10. At all. It’s a solid two POUNDS lighter than an AR-10. It’s smaller than an AR-10… it’s NOT – at all – an AR-10. So what is this thing? It’s the SFAR. *shrug* it is what it is… A .308 AR-15.
How did Ruger do this? Most all the small parts are all AR-15 parts. The difference is that you have the longer Magwell to fit AR-10 Magazines… Slightly longer receiver. And the BCG is bigger… About halfway between a 15’s BCG and a 10’s… It’s the only real unique parts group.
Even fully loaded, you can feel that the rifle is much lighter, and balances much better than any AR-10. Now, that would normally mean you are going to suffer from ferocious recoil. But thankfully, shooting the SFAR is actually pleasant if you are at an outdoor range. This is thanks to the extremely effective Muzzle Brake. It looks like it’s right off a WWII Hellcat Tank Destroyer… And if you are standing to the side of one being fired – it’s going to feel like that. But to the shooter, it’s just fun.
Everything on the SFAR is selected and designed to be light. The highly skeletonized handguards up front, and the Magpul SL stock at the back. Everything on it feels good, and I feel no need to change anything. The MOE grip even feels great, though it’s not my first choice. I’d rather have the Ergo rubberized grip, but not enough to bother spending the bucks and swapping it out. Anything else would probably just add weight and not add any tangibly better results. To complement the Light Weight and Simple approach to things that this rifle offers, the Optic I selected was the Primary Arms SLx 3x Micro Prism optic. It’s a very solid, compact little scope with a modest 3 Power magnification, etched reticle, with battery power illumination when needed. When I looked through it for the first time, I was highly impressed with the quality that exceeds the price. Think of it like a Compact and Light Weight ACOG for a fraction of the price. I had initially been thinking of doing a LPVO, but to get a good one, the price would have been at least 3 times the price of this one. And it would have added bulk and weight without advantages enough to offset those liabilities.
