While we introduced the original aluminum bolt carrier over a decade ago, we finally discontinued it after several customers had difficulties with its rather strict maintenance needs and changed over to our stainless steel design. As it turns out, we left a gaping hole in the market with some devoted customers hoarding the old parts or buying them up at steep prices. To meet all that pent-up demand, we’ve gladly reintroduced a new-and-improved and easier to run ultra low mass carrier manufactured from aircraft-grade 7075-T6, the reborn JPBC-1.
Re-engineered for improved reliability and performance with lower maintenance requirements, the new JPBC-1 is the ultimate in improved reliability and performance, especially when combined with a high-efficiency JP muzzle brake, adjustable gas system and Silent Captured Spring. The end result is a carrier that leaves your .223 shooting like a rimfire .22.
The JPBC-1 checks in at 2.9 ounces less than our 416 LMOS™ carrier and 0.7 ounces less than even the titanium carriers offered on the market today. Each unit comes as a complete kit including our JP precision-ground, one-piece gas ring as well as a titanium firing pin. Run in concert, this gas ring ensures perfect bore-to-gas seal fitment in the JPBC-1 and minimized friction to enhance reliability when fouled while the titanium firing pin eliminates any possibility of slamfire at the higher bolt velocities.
Once you’ve tried the new JPBC-1, like us, you’ll wonder how we could have abandoned the concept in the first place.
