Very nice!


I bought this for the Atlas Bipod I also ordered. It works very well and is extremely light! Order with confidence!

Product works great


I am using this with an Atlas Bipod, mounts solid and it's very easy to switch between rifles without tearing up my rails.Primary sent me the wrong rail by mistake but sent out a replacement same day before I sent back the incorrect item. Primary Arms customer service is top notch!

AD-170S, another top notch clamp made by American Defense!

Real nice QD clamp for the rail on the bottom of my Mcmillan stock. This in conjunction with the Atlas BT46-NC PSR Bipod No Clamp, makes my rifle stable and convenient(quick removal). I like both the American defense and Larue mounts! You get what you pay for. The American defense clamp won't mar your picatinny rail and it's a little cheaper than Larue. This rail also has adjustable tension for the picatinny rail, to get it just right. American Defense mounts are the best bang for the buck, in my opinion. <br>Primary Arms has always had top notch service. Excellent communication and quick shipping. They sell a huge variety of products for your firearm hobby.
