DIRECT IMPINGEMENT AR<br />
It is no secret that the Eugene Stoner’s AR platform is the<br />
best selling rifle in the U.S. with many manufacturers<br />
jumping on the bandwagon in recent years by offering<br />
their versions. It seems the ARs adaptability attribute is<br />
also its most abused quality. Primary Weapons Systems<br />
(PWS) is seeking to counter balance this trend towards over<br />
accessorized ARs with their “Modern Musket” direct impingement<br />
AR. That is right, PWS, the standard bearer for<br />
the long stroke piston driven AR, has introduced a direct impingement<br />
AR platform.<br />
The Modern Musket joins PWS’s existing MK1 5.56mm,<br />
MK2 7.62x51mm long stroke ARs, T3 rimfire, and recently<br />
introduced MK3 Precision Bolt. PWS is known as a leader<br />
in the quest for improving the AR operating system and cultivates<br />
an almost cult following based on superior customer<br />
service, unique interaction style with consumers and, most<br />
importantly, coming through on their promise of a superior<br />
AR rifle. PWS did not hang their hat on going with the typical<br />
short stroke piston in lieu of Stoner’s original direct impingement<br />
(DI) AR design; they took the less traveled path by<br />
utilizing a long stroke operating piston. We will define long<br />
stroke as exemplified by the AK47 of having op rod connected<br />
to the bolt carrier whereas short stroke consists of a more<br />
complex arrangement of tapped gas imparting force to an op<br />
rod that impacts another part of the mechanism that acts on<br />
the bolt carrier. PWS did not stop with the long stroke piston<br />
in their tweaking of the AR; rather they insisted on top quality<br />
components as well modifying the buffer tube connection<br />
to the receiver as well as bolt carrier design.<br />
While PWS long stroke AR rifles are well-known and respected,<br />
their entry into the direct impingement AR market<br />
is presently still relatively unknown. In the world of modern<br />
marketing it is nice to discover a product in the catalogue you<br />
