    Geisselles new SPR barrel with special gas system

    It has nothing to do with SPR barrels, John Hollinger is the Godfather of High Power Competition Match Barrels. And in regards to Geissele SPR Barrels...

    JP LRI-20 Barrel Offset from Handguard

    Yes I've got a few, so with Superlative Srms or SLR you're GTG up to .875 Or just by thier AGB, the new JP JPGS-12D2 are outstanding gas blocks. I did four of these exact custom PRS builds about 2 years ago, with either 22" or 24" Bartlein Barrels, all with .875 Gas Block Journals and SA AGB's.

    Okay Junior go back and focus on your reading comprehension and reread my post in it's entirety. Now let me grab some crayons and see if I can color this out for you so you can understand the topic at hand..... Obviously you don't know me or what I do. I probably own more JP Rifles than...

    Geisselles new SPR barrel with special gas system

    99.99% of the time when there's a shift like this QC definitely goes down so if anybody is wanting to order any barrels I would quickly purchase what they haven't stock now cuz there will be a lot of growing pains after the move.

    AR10 bolt Rub

    Let me get this straight... So the drop test reliably worked with all factory ammo? And feed ramps a clean and perfectly allied? And your our bolt is correctly head spac with fresh gas rings, with a professionally installed Barrel? And after all that you're still getting a stuck case that...

    Hollinger is selling White oak? Or is he stepping down and finally retiring?

    AR10 bolt Rub

    List of issues i would address first (1) Overly tight or dirty chamber, also check your Feed Ramps. ( If the Feed Ramps are rough or if you're seeing chunks of copper, polish with felt Dremel head and green polishing coumpound.) Next perform a Drop Test, remove BCG and push a factory round...

    AR10 bolt Rub

    The JP one piece gas Rings or Garbage! I stopped running them about 2 years ago and have switched to SpringCo Gas rings, I never really had any issues until I started running short barrels with exstended gas systems. Some of my Custom Builds started to become finicky with failure to feed and...

    AR10 bolt Rub

    It's not the gases and you're not having bolt rub, I've spoke about this in a few threads on here. JP put out a bad batch of QPQ coated bolts a while back, they are well aware of it. Call them up and talk to Dave, send it back and I'll give you a new one.

    Geisselles new SPR barrel with special gas system

    Oh hell's ya!!..lol I just don't need any more rifles, the Safes are overflowing something wicked to the point I'm playing fucking Jenga every time I want to grab something out. So my way of thinking is smaller guns are the way to go moving forward, so the new project is a SBR CMMG Dissent...

    Geisselles new SPR barrel with special gas system

    One of the ideas I've been kicking around is building a complete LMT set-up. I already have the MARS Ambidextrious Precision Lower and a 13.25" MPR upper. I could send one of the barrels to D-Willson and have him mod the barrel. What y'all think?

    I will.

    Geisselles new SPR barrel with special gas system

    Gotcha, I've probably got evey type of Upper you can think of, enhanced and standard. The quality of the current product lines from Geissele has been absolutely phenomenal with exceptional accuracy. At this point i don't see the need to build with enhanced uppers, when I do my initial break...

    I'll have in the PX but it will be in a complete Upper.

    Geisselles new SPR barrel with special gas system

    Good to see that the Gasport groove don't go all the way around so a clamp or set screw AGB should work perfectly, honestly I haven't had a recent Geissele barrel that was over-gassed. The new Gas Port diameter on the standard Barrels are gauging at .075-.076

    Geisselles new SPR barrel with special gas system

    My tracking information has the barrels arriving on the 6th, I'll post pics with full details when they arrive. I have everything needed to assemble them into complete Uppers. I went with the following parts. Vltor Mur FDE upper receiver for increased rigidity over the standard Geissele...

    They're selling complete Uppers with the heavy barrels as well.

    Geisselles new SPR barrel with special gas system

    It's not as complicated as you guys think, its just spreading the gas part pressure out of three ports instead of one... simple math, take the average PSI that thier standard single gas port barrels produce and divide by three. The end result will be the ability to run multiple small gas ports...
