JP Enterprises found they had a winner on their hands with their original, AR10 style .308 and .260″ rifles. On standard AR10 style rifles, the distance the rear charger had to be drawn was excessive and required a great deal of strength due to the powerful recoil springs on those rifles. It was also too easy to bend the charging handle, rendering your weapon inoperable. JP got around this with their L1A1/Imperial FAL style side charging system which had the added advantage of letting you maintain cheek weld through the charging cycle. JP then found they had so much interest in a 5.56mm version that they decided to bring one out in the smaller AR15 format. These rifles had dedicated lowers and the uppers were not compatible with existing ARs, excluding JP from the retrofit upper market. Not everyone was totally sold on the side charging concept and some wanted to retain a rear charging handle. JP listened to these customers and introduced the JP PSC-11 Side Charging AR upper which would fit mil-spec AR15s and retained the rear charging handle for those that wanted this facility.
