    Geisselles new SPR barrel with special gas system

    Yes for mock-up purposes it has the Heavy Contour 16" Geissele in it now, but the it'll be for the 18" Cut rifle SPR Barrels.

    Here's a quick mock-up of what the Geissele 18" SBR Barrel Uppers will look like.

    New Build: #1 & #2 (6ARC Radian/ Bartlein) ( Geissele / Craddock Precision)

    Just took this girl out for her initial range session today to dial in the gas system. All five round groups shot with Hornady Factory 105 black ammo. Raidin Build Kit. Geissele SSA-E X Trigger. Vlotor A5 H2 Buffer system with Dark Hour 13 position receiver extension. Paul Ross 22" Bartlein...

    Geisselles new SPR barrel with special gas system

    Ok here it is, with this bullshit Mickey Mouse front and rear bag setup the point of impact shifted half inch right, having no front end stability I was having a hell of a time controlling the rifles CANT which ultimately caused a few Flyers. Hope this helps. Jake

    Geissele's New Heavy Barrel and SOLGW Broadsword project. (Up Date, 1st Load development session 18DEC24))

    The 73 grain projectiles from Hornady and Berger are truly exceptional out of these heavy Contour Geissele barrels both in 14.5" and 16". The .181, isn't the smallest five grand group I've ever shot but damn close.

    Geisselles new SPR barrel with special gas system

    All 5 shot groups of various types of factory ammo with the exception of some cheap 55 grain stuff I use to season the clean barrels before I shot the groups and a couple random 77 Grand tmks I had hanging around. The Geissele heavy Contour barrels truly love the 73 grain projectiles. As far...

    Geisselles new SPR barrel with special gas system

    Yeah I know that, I just wanted you to see what the current 16" and 14.5 heavy Contour barrels are producing pretty hard to beat that accuracy in fact I'm almost kind of skeptive that accuracy game will be marginal. I took both of my 16" and 14.5" Geissele heavy Contour barrels out yesterday...

    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...
