Vltor PKM Receivers in production

Compared to conventional PKM receivers, Vltor’s receiver is more robust, rigid and wear resistant. Vltor has researched the PKMs history and found the weaknesses of the existing chassis and moved forward to improve upon its design. For example, the PKM receiver was notorious for cracking around the rear trunnion rivet holes. This was cured through increased strengthening around the said holes. Another downside to the original PKM receiver was the excessive wear on the receiver’s rails. Vltor has remedied the problem by the eliminating the conventional “stamped” rails by replacing them with fully machined, heat-treated tool steel rails. Finally, with the installation of the tool steel rails, the Vltor PKM receiver is less likely to flex or twist during operation, when compared to the original
