Good stuff. Used this to get my pvs-14 up to a suitable level to my eotech which is mounted on a unity fast riser. Worked like a charm. Product is exactly what you’d expect from kac, and operation parts got it to my door ultra fast. Thanks!

Been looking for one of these for quite some time and Operation Parts came through for me

Excellent customer service on a part that's difficult to find in stock. Fast shipping and easy site navigation. Will definitely shop here again.

The Knightstick is everything I expected from something that wears the KAC name. Operation Parts shipped quickly and ensured my Knightstick was properly packaged and protected. Buy with confidence.

Hard to find parts at a great price.

These folks are top notch! Picked up an KAC SR15 upper from them! 100% satisfied with service Before and after the sale. Thanks Again!

Great product at a great price from an outstanding company! Thanks Operation parts!

Awesome

As the previous review stated: priceless piece of GWOT history! As soon as this rail comes in, you need to act fast when you get that notification, otherwise you'll be at the mercy of scalpers on GB or the Bay. Not to mention OP's awesome Mil discount, and same day shipping! Absolutely love my rails, buis, and the other Knights gear. You have a customer 4 life!!

Product as described and delivered in timely manner.
