( 5 out of 5) Favorite AR15

by Nicholas from Overland Park, Kansas on September 25, 2014

I don't normally write reviews, but feel I should share my opinion on this rifle. I have owned 4 different ar15s: Windham Weaponry, Smith & Wesson, DPMS, this Sig Sauer is the 4th. All DI systems except the SIG516.



The SIG516 is solid and has excellent workmanship, came with a Magpul stock and a Sig grip. The iron sights that come with it are very strong and accurate. No need to ever buy back up irons sights when the rifle comes with a top of the line iron sight already. Came with a sling and the rifle has 6 different spots you can mount your sling too. Ordered an Aim Point Pro for it but couldn't wait to shoot it so went shooting with just the iron sights out south on our property. 700rds through the rifle, no hic ups at all and was dead on. Farthest we were shooting was at about 120 yards any misses were due to operator. Gun stayed clean in the bolt carrier group and didn't get as hot as other DI systems. Bolt carrier group is impressive. What would have been the gas key is integrated in the bolt carrier group. Where the bolt goes is chrome lined as promised for maximum reliability. Back of bolt is cut in a way to reduce weight and anti tilt. Back end of bolt is shorter than others so I don't believe it is classified as a full auto bolt carrier. Ambi mag release is neat, though I'm so use to using the mag release on the other side of the rifle I never used the ambi.



The piston rod is very easy to disassemble and clean and with 4 different mods it is impressive. Put a mod 4 BCM medium latch charging handle on it and Magpul angled grip with an Aimpoint optic.



I will be replacing the trigger with a different mil spec trigger. The only thing I don't like is the trigger isn't ultra smooth, it's not awful but with the rest of the gun being such high grade I was disappointed with the trigger. Polished the trigger a little and didn't help much.



The gun is NATO approved, you can find the over beach test online youtube or sigsauer.com. The gun came through all the torture tests. There are very thorough videos on Sig's web site that go into detail and talk about the SIG516.



Sportman's Outdoor Superstore was great as normal, two day shipping which was free. Their customer service is the best and you cannot beat their price. I shop around when I buy guns and Sportsman's is almost always the best deal.
