Choate Machine & Tool: Premium Rifle & Shotgun Stocks, Accessories in Canada.

Our first products were magazine extensions for Remington and Browning shotguns. In fact, we were the first to offer magazine extensions to the public.  We were also first to offer after-market folding stocks and flash suppressors for the Ruger Mini-14. In 1981 we began making OEM parts for major manufacturers. We have since made parts for Smith & Wesson, Remington, Mossberg, Savage, H&K, Winchester, Anschutz, Marlin, H&R, Nighthawk,  Ruger, Beretta, Springfield and Kahr. Choate Machine & Tool remains a top producers of OEM parts for the firearms industry. From a modest 1,200 sf building to three separate factories for injection molding, investment casting and final assembly, we now have over 95,000 sf under roof. roof.
