Since their introduction to the U.S. Market in 1985, the Poly Technologies rifles have become some of the most collectible and sought-after guns in America. As the exclusive importer of Poly Technologies firearms and parts from 1985 to 1989, Keng’s Firearms Specialty, Inc. (KFS) has access to documents and product history that can add value to your Poly Technologies collection. Due to popular demand, KFS is now offering a certificate of authenticity for all Poly Technologies rifles that it imported into the United States.
The certificate is printed on archive-quality 100lb. paper, with a Poly Technologies, Inc. logo and watermark and KFS logo. The certificate provides the place of manufacture, import date, sold date, and other information valuable to the collector. Each certificate is signed by David Keng, founder and former president of KFS (now retired), and his son Da Keng, the current owner and president of KFS.
Each signed certificate is available for $49.95, including the processing and shipping fee. Please allow two weeks for delivery.

It's great to have this verification on my Legend but I was hoping for a little more information to go with it; knowing the year it was built, how many were shipped and most important who it was sold to. I bought mine in 1998 in Georgia at a gun shop new in the box. I always have been curious about the nine year gap between the date sold by Keng's in 1989. Thank you Polytech

I am pleased to find out where my AK-47 came from, all I knew was it was stamped Kengs Firearms. This will help me identify it's origin.

This certificate adds value and is a must have for a piece of military history that will only become more valuable over time.

I'm glad this product is offered. I was able to prove the import date of my rifle. When I had the rifle appraised, this certificate increased the value the rifle by slightly more than the cost of the certificate.
