  • Outstanding AR Rifle
    Review by SIG 516on 3/5/2020
    I recently purchased a SIG 516 Gen 2 rifle from Osage County Guns. This is a superb AR. It is well designed and incorporates many fine features such as an ambidextrous safety lever and ambidextrous magazine release. The rifle comes with excellent BUIS's and with an excellent sling (plus a 30-round magazine).. Attention to detail and quality is evident everywhere with this gun (an example of this are the multiple sling attachment points on the stock, receiver and forearm). My only criticism concerns the trigger, which had a pull weight of just under eight pounds . This was easily correctable with the addition of a TriggerTech adjustable AR trigger. Even with the trigger issue, I would rate this rifle a solid five stars and can recommend it without reservation. If you are looking for a piston type AR, this is the one to get.
