Oulun Työstökeskus Oy, OTK for short, is a Finnish fine machining company that designs and produces suppressors and other gun accessories.
You probably know us as the makers of the SAK .22 rimfire suppressor, which we have produced since the early 90’s and sold over 250 000 pieces to date. Along with the SAK and ArmaSe suppressor ranges, we also make adapters, bipods, picatinny rails and cleaning rods.
Everyone in our company are passionate shooters and hunters so we are always developing and testing new shooting accessories to be used both at the shooting range, and in the challenging Nordic environment.
We design and manufacture everything in-house, apart from the raw aluminium material and anodization process, at our production facility in the old army barracks of Hiukkavaara, Oulu.
