I lucked out and got a BLACK RAIN ORDNANCE AR10 from a guy that was hard up for cash. I do not think it had ever been fired except to function test it.
It came with a custom 20 inch match grade Shilen barrel. Magpul Industries PRS GEN3 Precision-Adjustable Stock
Also a Geissele Hi-Speed National Match Trigger that is so smooth it's like glass. BCM changing handle. When I pull the charging handle back. It's so smooth and easy. It's like a well oiled engine.
He had it Cerakoted in dark earth. I added a one piece adjustable gas block and gas tube to it. The gas block and tube came together as one piece. I can't remember the name right now.
He had close to 3k in that RIFLE. I got it for 1800.00.
I'd like to to put a shorter barrel on it, as well as a different stock. So it'd be easier to hunt with. But the way it is set up now. It is a tac driver at 800 plus yards using 175 grain match.
I'm in no way knocking 308 ARs. You just need to be careful when buying one. Plus when setting it up. You need to put an adjustable gas block to cut down on felt recoil. You can make them really really soft shooting weapons.
I bought the SCAR 17 and SCAR 16 because I had the funds to do so at the time and really wanted them. I did have buyer remorse at first. But now......Id sell all my other guns first. They are my go to weapons.
I shot 2000 rounds through the SCAR 17 once before cleaning it. I just wanted to see if it would malfunction. It didn't ....then again I shot 3000 rounds through an AR 15 with an ARES PISTON KIT on it without any malfunctions.
But at around 4k rds. The ARES piston kit did wear out the buffer tube portion that held the spring and part that held the buffer and buffer spring in the buffer tube. A easy fix on the buffer tube using a drimel tool.
I switched the piston bolt carrier out to a different make. I also had to put in a new piston rod and measure and grind it to length. Just a tad. But that's recommended in the directions anyways with the old ARES PISTON KITS.
But it's like everything else in life. You don't buy something you do not like. It's like my night vision and thermals. I know how to build night vision. So I built night vision and sold them. Each time upgrading to better and better night vision until I had what I wanted. Same thing with guns.
