Grest item and great business

by Doran28, from FL, United States Written on January 28, 2019
Great description item shipped fast. Also alot cheaper then the sig m400 setup. Only wish they would sell the lower. Looking forward to another easy transaction with optics planet. They also have such great deals with coupons and rebates I wonder why anyone would shop anywhere else.

Great products, great prices, fast shipping

by Consco, from IA, United States Written on April 2, 2018
Sig parts speak for them selves.
We have made multiple purchases from Optics Planet and will make many more.
They have all of the quality products at reasonable prices and the shipping is fast.
If they do not have something in stock they will let you know when it will ship. These guys are a great business model!
Thanks OP
