It should be. It will perform for you.

I"m DOWN with that, man - let's make some crazy shiit!... I DEFINITELY see a 500 Blackout in my future, and that is NOT a typo.

Been 5 long years, but I'm going back...

I see no reason at all to NOT do this...

He layed that comment as bait... Who's gonna post the video clip?...

WOW! Mine is 13.5" barrel, "midlength gas" for lack of a better comparison to "Armalite AR-10 Carbine gas" - damn close enough - and 0.081" gas port diamater. That seems SMALL, for 2" of gas system down. I would punch that thing to 0.070" right now, just because the gas port is 2" shorter than mine - carbine gas versus midlength gas. 1/4" wooden dowel down the barrel as stated, drill bits out, go slow. I wouldn't send it back for that. I'd take the Makita drill to it.

Yep! I completely agree. MIrage disappears at 12mph. Your screen goes blank, figuratively. That tells you that you have no wind, or your wind is above 12mph, and you know the difference between those two. Move off-target by 45 degrees and try to read the mirage. If you can read it at 45-off-target, multiply what you observed by 1.4. If you cannot read it 45-off, try to read it 60 degrees off-target, and multiply what you observed by 2.0. Say it washes out on you, looking at the target. It went to 12 or over. Move off 45 degrees from target. You're can't tell what you've got for mirage, so you move off-target to 60 degrees. Lets say you observe a 7 or 8 mph wind at 60 degrees from target. Multiply that (split it to 7.5 for personal comfort) by 2.0. You have a 15mph wind on-target that you need to hold for, or dial for. If you got that 7~8 reading at 45 degrees, you'd multiply that by 1.4, which would have given you 10.5 mph on-target. Sometimes this is very helpful, because it's tough to tell a 10mph wind on-target - it looks like flat mirage, it washes out and disappears and comes back as flat mirage... You don't have to wait for the mirage to disappear to use this technique. You can also use mirage to accurately determine wind direction. It's WAY easier to use a spotting scope for this, but you can use your magnified optics on your rifle. Start watching the mirage, and scanning (under a 12pmh wind). Slowly move in a 90-degree arc and determine where the mirage goes straight up - that's your wind direction, either to your face or to your back, and it's pretty accurate.

They are. Just not as prolific as Aero, for sure. At the deals you can find on the Matrix sets, it's crazy not to have at least one built on them.

Fucking Instigator.

That's no way to measure a gas port, honestly - not trying to piss you off, so get that now. You need to "pin it" with measured drill bits to get it right. I can make a 0.030 difference in a gas port size, in how I hold vernier calipers to it. Insert indexed drill bits that fit - until you get the next one up that doesn't fit - and measure that one with the digital vernier calipers. Then go measure the last one that fit. That's the only way you're gonna know the true diameter, without a precision pin-fit caliper that's designed for this small stuff. Gotta pin it, man, and see what it really is. Your buffer is about as stout as it needs to be, in weight, and from that manufacturer, the length is right. Blue loc-tite is never used on a gas block or rail. Anti-seize is never used on a barrel nut. Don't hate your "gunsmith" for that - those things are not used on those areas, and they didn't use them - from me, that's kudos for them for not fucking it up by using that stuff in those areas. I've done this before for another guy here that I didn't know beforehand - but I've done it for many guys that I DO know here. If you want that upper receiver setup teched out and fixed, I'll do that. Ship it, I'll find out what it's doing and FIX IT, and ship it back to you. I'll go through whatever I have to in order to test fire it, with a video (swapping uppers if I need to, if your upper doesn't mate to something I already have) - and when it runs, great, I'll send it back. We're talking one working weekend on that, not weeks.

That depends on how close I can get to that squirrel that is pissing off Shepp...

It's an EXCELLENT resource, brother. There's a VALUABLE TON of information in Rex's vids. They are fantastic. He's got some insane skills, too.

This is really what I'm talking about, right here. You went a completely different direction, will, and I understand why now. The isn't a challenge, call-out, anything like that - this is two different disciplines were talking about here. You're the Camp Perry flat range shooter, all your distances are known, and you only have to worry about wind - and personal skills. Camp Perry is the ULTIMATE TEST of personal skills, right there. I used to go to Camp Perry every summer, as a kid, for different reasons, and I've seen it in action. Once one puts themselves into an unknown distance arena, with no electronic technology - the world changes. Great shooters suddenly suck. Know why? Range estimation takes a toll. Wind calls might be there - but that doesn't matter if you don't know how far the target is. Wind is secondary. Range Estimation is primary. If I can range my target, but suck at wind calls, I'll get close, then I can adjust - most of the time, in a wind that's under 10mph full value, I can "half-target" the shot and hit the target, at distances to 800 yards. I just need to know if it's right-to-left, or left-to-right. If I can't range my target, I won't even get close - it's just a guessing game. Toss some elevation in there - and zero electronic aids - and the whole world goes upside down. Everything gets crazy after 15 degrees of elevation. It is literally exponential beyond that inclination. We're talking about completely different skills, from completely different perspectives. I understand why now.

Wait... WHAT?!!?

He's probably so impressed, he'd run out and get two blowjobs and bring one back for you. I'm just sayin'...

That shiit is wicked. I love it.

I like that scope, Doc - alot. If I liked MOA alot, I'd have a pile of them. It's great. Until they make that reticle illumination pattern in the mil scopes and the HUD DMR scopes, that one will certainly be the king of "great scope with GREAT illumination pattern." Until then, I'll have to suck it up and keep using MEALS. Batteries die - at the most inopportune time. Technology- fails. Even the illumination can go out in my scope, and it won't be as easy to shoot 450 yards, at night. But... I can still do it. I know how to accurately estimate range, at any distance, without a laser range finder. I can do it with the graduations in my scope reticle, and the information that is stored in my brain, on target sizes. The batteries can die in my Kestrel, and all the sudden, I have no weather data, no wind data, and no Applied Ballistics program to tell me what to click to - as soon as my laser range finder bluetooths it to my Kestrel. They both have dead batteries now. But... I can still determine wind direction, wind speed, and make the adjustments necessary to hit my target. With my scope, and the information that is stored in my brain, on wind data. I will have to reference my printed dope charts if the wind is above 12mph, though. If I have to go off-angle to measure the wind speed, it's already above 12mph, and I'll need to look at my charts. But I can still do it. Does Camp Perry shoot an unknown distance course of fire? I think every shooting program there is at known distances. Get into an unknown distance situation, no laser range finder, and lay the smackdown on some targets. That's exactly why the high angle shooting is so different. It's the same as flat shooting, you just add another perspective that you have to master, and one more things to memorize and run the math geometry on. Come on out, with no gadgets, and let's get it done.

Damn. A2 buttstock screw in an A1-lengthed stock. That would have taken me forever to figure out here... Big Props on the quick diag from them...

A PA-10 that runs, makes me happy. Seriously. Very well done.

It's 300BLK because it's a .30 cal device with 5/8 x 24 threads - that is the same threading we have on the 6.5 guns - mine are .260 Remington and 6.5 Grendel. The device works great - how is it compare to no muzzle device on there? I have no idea- I haven't shot it with no muzzle device. Worrying about the sound is not a reason to get a brake, but the way you've been describing things in this thread makes me wonder if what you really want is a brake, at all. Only you can answer that one. Many, many times, using a brake on the end of your barrel makes it seem LOUDER to you, as the shooter. That combo above doesn't cancel each other out, but it's pretty easy to shoot. With just the brake, it felt louder, and the CAGE device does do a little bit for that, in terms of felt or perceived concussion. That 6.5 Grendel that it's on barely wiggles the crosshairs in the scope, when you fire. The VG6 6.5 Gamma Brake is what's on my .260 Rem. It's 0.860" O.D. It's a 3-chamber brake, so that CAGE device would only cover the first two chambers on it - i.e., it mounts to it, but it's not made for it. The CAGE is made specifically for the 2-chamber brakes.

When does it arrive?...

This is what I put on the Grendel, and it would work on your 6.5 CM gun:

The very definition of a brake - it's gonna be loud. You might want to look into a compensator instead. Or, and AAC Brakeout with the AAC Blastout mounted over it - that combination will redirect the concussion away from you, as the shooter, and still give you the benefit of the brake. I'm running a VG6 Gamma brake on a 6.5 Grendel, with the VG6 CAGE Device mounted to the brake. It gives me the benefit of a brake, but the CAGE device is a "diffuser" of sorts, that disrupts that side blast from the brake. I still wouldn't shoot it with no earpro, though.

Call Badger Ordnance, and see if they have something for you. The issue you're going to run into will probably be threading. Most .875" diameter brakes are for 3/4" x 24 threading, not the 5/8" x 24 that you need. You try the VG6 Gamma 6.5 brake?

Yep. We had a complete separate training class on wind reading at the Fall Shoot, and I specifically discussed using your scope to determine wind at different distances between you and the target.
