Nice job. I know the feeling after buttoning it all up. i would love to know how that brake holds up on a gas gun. Please update.
I had the brake on for 8 months (then went to a Dead Air Suppressor) and it held up great. It still looks like new. When you first put them on, you need to reach up and tighten it several times before it completely settles down and stays tight. Without a doubt, awesome brakes.

Seekins sp10 builders kit, barrel, adjustable gas block, bcg, geissele national match, magpul prs, jp silent capture, tbac ultra 7, mdt arca rail. A little bummed that they didn’t do an XL length gas system as I wanted to run the Seekins throw lever adjustable gas block but such is life.

I thought I had posted mine before but guess not. It’s fairly plain Jane compared to most here but it shoots 168 FGMM into tiny groups and is fun to shoot.

Just a factory Mega Maten Megalithic with 18” barrel. Eventually I will get around to upgrading the stock mil spec trigger and ambi safety as well as the scope but it was sitting free in my safe and works for now.

Winniethepooh what kind of accuracy are you seeing out of that setup?
I have a billet Spikes/Sharp Bros setup that I am looking to change into a 22in 6.5 Creedmoor
I was leaning towards the Bartlien setup

Picked up my first large frame gas gun on a trade a couple days ago. This thread has given me a lot of ideas for a build!

As of now, I'm going to be going with a Triggertech AR Diamond, Criterion Hybrid Contour 20" .308 barrel with headspaced JP BCG, and a Nightforce NX8 2.5-20. That should get the ball rolling.

Have you shot the criterion barrel yet? I went with the same barrel in 18" for this build.

wow, looks nice. looks like a turn-key Aero M5, complete with their new Atlas S-One handguard. should be fun! since you're swapping out the barrel, you might consider an adjustable gas block, if your new acquisition doesn't have one already. or, you might just consider building a whole separate upper for your new barrel. might be an Aero Labor Day sale coming up.

I haven't ordered it yet. I'm going to continue to do some more research throughout the week. I will buy all the components this coming weekend.

The guy I got it from built it from all Aero stuff. The current barrel is a 18" BA. It has never been fired. I am definitely going to go with an adjustable gas block though. I have them on all my AR15 platform rifles/pistols. Should be helpful if I decide to click the mouse on a .260 or 6.5 creedmoor barrel instead of a .308...

Looks like a few MK5 3.6-18's. Are they worth the extra $500 to $700 over the SHV 4-14? Going on a suppressed 16" that won't be shot more than 1k.

In 308 for now... POF lower, (pof doesn't make their own stuff) a 1of 30 upper Molon Labe gas upper made by a machinist at the factory who made POFs uppers lowers, pistons, and hand guards back in 2011 as a custom run. Fortis quick change hand guard, Mega barrel 18", AAC brake, CAA grip (like the adjustability run them on all my ars) and finally the Spuhr 20.6moa 6mil cantilever mount cradling a Leopold MK 5 5-25.

Figured I would throw up a quick update of my 308... Took it out to test out factory loads in it and it ran perfect, shot pretty decent.

I know my optics set up is pretty cheap, but it works for now until I can get something better... Believe it or not, this scope, rings, barrel, bolt, stock, trigger and bipod were all picked up here on the hide...

20191005_185311.jpg

Today's groups:

20190924_140116.jpg

Yea just 4 shot groups, I don't have much of these different loads... Still, pretty good I thought for a second hand SP10 barrel, $75 scope on a cheapo Weaver riser shooting factory loads. I shot the 185s at my zero instead of bringing it up 1.5MOA like the 175s... Otherwise they wouldn't be low, my bad there...

It's been a hell of a rifle so far, never misses a beat... Gotta get some time to spray some Aervoe on it will make it perfect for the woods.

What barrel is that? Is that the Troy rail made of Carbon Fiber?
