This might be a decent option for a tight fitting gas block.
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
Is that a keyway for a tabbed gas block?
Edit: Must be for their shitty cast gas block which now has a dowel pin protruding from the rear https://geissele.com/super-gas-block-black.html

Would you be able to measure the distance between the centers of the two gas block dimples? I’m curious what the size is. I’m sure they spaced them for their gas block but I’m not a fan of their block since it’s cast instead of machined. Hopefully there is another block that lines up.

Finding a tight fitting gas block can be a crap shoot in my experience. I don’t even worry about it anymore. If you do have a loose fit where the block slides around with little resistance, you can easily fix it by sealing it with Loctite 620.
Here is the method that I use that works well for me. I haven’t seen any carbon leaking from my gas blocks after applying the Loctite this way.
First, apply a thin bead of Loctite 620 around the barrel, directly in front of the gas block shoulder but behind the gas port. When you slide on the gas block, the rear of the gas block will be sealed. Don’t pull the gas block forward because you don’t want to smear the Loctite over the gas port.
Next, use the gas block set screw hole that doesn’t line up with the gas port hole. You are basically using this set screw hole as an access port to apply Loctite around the circumference of the barrel. Spin the gas block around the barrel, dabbing a small amount of Loctite 620 through the set screw hole, at a few different positions around the barrel. Then, spin the gas block around a few more times to spread out the Loctite. You’ll want to clean out the excess Loctite from the set screw threads before installing the set screws.
If you do it right, you’ll get a thin layer of Loctite behind and in front of the gas port that will seal everything up once cured.
EDIT: I also apply some Loctite 620 to the gas tube, behind the gas port hole, before sliding the tube into the gas block for pinning.

I think @Bigjake83 has also posted pictures or explanations of how he seals his gas blocks. This is just a simple method that has worked for me. If it doesn’t 100% seal everything up, it will get you 90% of the way there and carbon will quickly seal up any remaining leaks.
It was tongue in cheek. 620 is wicking grade though and you should be able to apply it through the front of the gas block and gas tube (if block has open front).
I believe that Loctite 290 is the whicking grade thread locker while Loctite 620 is a high temp sleeve retaining compound. They are both green so it gets confusing but they are designed for different applications. I think 620 has a much higher temperature rating as well.
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 in I'll perform a POI shift test to see if moving to a enhanced is warranted.
The current GFR line is utilizing the traditional upper to handguard system and they are showing exceptional accuracy, so again do t see the need.
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?

Pump action AR with a FRT or nothing
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 MK4 9MM 10.5" Complete Upper that I'm pairing with a ADM UIC Ambi Lower.
I think the radial delay is really interesting especially for 10mm/45. That new Griffin Armament boltcarrier is interesting as well.
I just did exactly that. Just got my Craddock Precision Bartlein barrel back from D Wilson today.
I probably won't have time to shoot it until this weekend, but I test fired this barrel in a mock-up before sending it off, it's a hammer.
I'm going to run a Vortex 1-10 on this, but I temporarily slapped on a Nightforce so it's ready to go in case I find time to shoot on my lunch break this week.
This is what I'm doing. Although Ive got a WOA barrel headed my way. Didn't know about this one when I ordered.

Sold it completely and they are moving to Nevada I think it said
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.

That was my thinking, have used a few parts from them but hope QC and CS don’t suffer tragically in this shift.
Only time will tell I reckon
It'd be sad to see that happen, but it also seems like the market is saturated with companies making decent SPR barrels.
If mine doesn't shoot I'll probably order a Geisselle.
Has anyone shot theirs yet?

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...

Just finished this build today, looking forward to running it through it's paces. The Broadsword Builder kit is extremely rigid and well built with clean machining work. The face of the Upper Receiver is true and showed virtually no Runout The Upper with it's heavy construction and increased...

I could be wrong but I belive that's a completely different barrel. The one in this thread is a 416R rifle cut barrel and the one in the other thread is CHF.It has nothing to do with SPR barrels, John Hollinger is the Godfather of High Power Competition Match Barrels.

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 and I will post pictures of the groups here in a second, thay all look to be Sub Half MOA.
It's kind of damn hard to beat that.
Yeah, those are pretty fantastic results that are hard to argue against...
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 as I'm aware of this is groundbreaking accuracy out of chrome line barrels.

New project. Prolly use a aero enhanced upper with sgt of arms handguard
If RD15 stripped uppers were available I’d probably use that.
I'm at the range right now I'll do a point of impact shift with a Geissele 16 in heavy Contour Barrel it has their upper receiver and 16-in mk16 handguard
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.

The groups above groups and the ones I just posted we're shot with a CAN and Hornady 73gr Elds
