Hugo, MN – JP Enterprises introduces the solution for poor-fitting AR-15 and AR-10 upper and lower receivers. Loose receivers especially are the bane of most AR builds. This loose receiver fit is annoying and cheapens your rifle but it also limits its accuracy potential. JP MicroFit™ takedown pins bring most receivers up to a rock-hard fit and can dramatically improve even the sloppiest receivers.
Although most poor fitting receivers are loose, some are too tight. Very tight receivers, such as post-Cerakote, can be remedied with the undersized pins.
MicroFit™ pins come in three sizes; mean, oversized and undersized for both the front and rear of the receivers. The mean pins match standard takedown pin sizes while the over- and undersized are offset slightly over .001 from that size. This small variation allows for the small slop or overly tight fit in receivers to be significantly improved. The pins allow for five unique fits, and the maximum loose and tight combinations will significantly change receiver fit.
“We’ve been fighting the issue of poor receiver fit for 20 years, which is when our original Tension Pin debuted,” stated JP Enterprises founder John Paul. “Ask any bolt gun shooter. They will tell you that a rifle loose in its stock will not reach its accuracy potential. An AR with a loose upper/lower is no different. The MircoFit™ pins require no modification to the receiver. They simply replace your current pins.”
MicroFit™ pins are bright polished to a near mirror black finish with a durable QPQ coating. This provides for an ultra-smooth finish and feel with the wear and corrosion resistance of JP’s bolt carriers. All pins feature a two-faceted punch or bullet capturing recess. This allows the user to apply force to the pins safely without risking scratching the receiver.
MicroFit™ pins will be sold as individual pins and as replacement sets. They will be standard on all JP rifles, ensuring a snug fit and pleasing aesthetics.
