never mind guy's ,according to Eric JP is no longer selling upper receivers unless You buy the rest of the upper with it. This SUCKS for those of us who were building a rifle at the time. Apparently if You want to build a good three gun rifle You may want to go Loki or Stag or some other brand like Lancer,They make high quality stuff and dont have the inventory problems that JP seems to be having. .I will probably be selling the JP stuff that i already bought, since JP would rather make more profit than keep satisfied customers, AND FUTURE BUSINESS but I guess not. JP HYPE HYPE HYPE. Very freindly people and quick to reply but not so dependable on when trying to buy what they advertise. Even now ,go to theyre sight and receivers are still advertised and backorder option given ???????????? Even theyre dealers say this????? too dang broke to buy an entire JP so back to the peoples choice Loki ,Stag or Lancer I guess . Yall can keep Your JP stuff and I'll use one of My other dozen or so other AR's till I get My new comp gun built . THANKS JP
