Yeah. 5.56 is more plentiful.

I want 277 Wolverine to gain some traction. Supposedly close to 6.8 SPC in terms of performance with only a barrel change required. No special brass or mags, easily formed from .223 unlike the more difficult to form 300 BO.

  Second bullet is good bullet.

  Only 8" barrel.

From what I see on FNForums, a "6 bolt" receiver to barrel trunion mounting system, probably among other differences.

> if they put any work in hand-fitting and lapping the bolt to the barrel extension as you should on any precision rifle

I don't have anything to base this on, but I would not expect any hand fitting from a company like FN on a product like this. Probably tighter QC standards, but I don't think they'd pull out the Belgian gnomes for this one.

Versus the "4 bolt" mounting. This pic is from my 16, but the barrel on the 17 mounts up the same way.

And by the way, it does return to zero pretty well. Which I was slightly disappointed with since my aimpoint is cranked 3/4 the way to the right. That's right, it returns to zero, way off to one side.

(But then shoots great... so whatevs.)

Damn, back before the 16's receiver had been thrown into many a dump barrel.

Here's my ACOG zeroed for my AR behind the reddot zeroed for the SCAR. The AR zero is probably pretty centered...

I guess in that sense the SCAR's gas system sorta represents the twin turbo 4-cylinder of the Ford Focus RS wherein it squeezes as much out of its input as possible but is very highly engineered and necessarily high-precision. Whereas the system I'm most familiar with is direct impingement or other more crude, higher volume or vented piston systems which is basically like an LS1 that is basically old, crude technology at its most refined that you can basically tune to do whatever you want. But it's always going to be less efficient for its output than the new hotness.

But maybe that's a dumb comparison.

Things that were meant to go in rifles most of the time suffer few constraints and as a result can be all sorts of shapes and sizes.

Calibers and the firearms they go in really is a broad topic so this cursory overview is meant more to help you narrow your question if you want to know more.

  This is an old US Army training video on ballistics that might help shed some light on powder burn rate, pressure curve, barrel length, etc. A lot of it isn't relevant to your question but it helps explain why cartridges on the "pistol" end of the spectrum use smaller volumes of faster burning powder and shorter barrels and and cartridges on the "rifle" end of the spectrum use larger volumes of slower burning powder and longer barrels.

If you're interested in old time .mil training videos, archive.org has them all available as high quality downloads. you don't need to stream them, you can make a big collection and stash them with your anime so you have something neat to watch if the internet dies. http://www.zenoswarbirdvideos.com has a lot of the old aircraft training films organized.

Just watched the P51 training video, good stuff.

absolutely solid dump, thank you for your contribution and for leading by example by being a good citizen of /k/

glad you enjoyed it

whatever you choose you can certainly do better than diamondback. how about a nice masterpiece arms carbine?

There is a retarded amount of easy money to be had from posting gun pics to IG. They don't all have to be selfies, you can take picture of the guns if you want.

I think my favorite is ridiculous magnum revolver cartridges being fired from absurdly short barrels. Bonus points if the owner actually got a custom carry rig for the fucking thing. Pic is S&W 460ES.

He's probably better of not practicing, otherwise he'll develop the flinch from hell.

thanks for getting opchan shut down, faggot

How come 7zip refuses to open this?

I'd guess that the original was a PNG (lossless compression) and that there is a jpeg (lossy as fuck)

>>107725
as much as i like jpegs and their trippy artifacts, whoever decided to resave that pic as one is retarded and whoever reposted the image without realizing that it was fucked is is clearly not involved in 3d printing and saved the image for some other use.

Never bought from him. I see the website is still Web 1.0 and looks like a 80yo granny designed it. I am surprised there are no random lens flares.

He does have some cool stock though...might just send him my C&R copy...

I met and spoke with him a couple months ago at his home office to make a sale to him. He is incredibly friendly and an excellent person to do business with. Very interesting man. I've ordered two rifles from him and have had them the very next day.

Gonna go look at the FN tomorrow, may also look at their SCAR 16.

Another fren was sucking X-95 dick. So not an AR but very interesting in theory. Might like, IDK.

>>107605
I'm a big fan of the SCAR 16. It's a great shooter and the only problems I've ever had with the gun were short stroking when I put the gas regulator on suppressed, and when I managed to jam a round in the chamber backwards while trying to admin unload the gun. (Rolled snake eyes, critical miss.)

A Gesissele Super SCAR trigger is a must and I recommend some kind of rail extension. (PWS or KDG)

But, in reality, I hardly shoot mine anymore after building an AR for competition with an adjustable gas block and lightweight recoiling parts. The SCAR is heavier and has a huge amount of reciprocating mass. It's like the gun just pushes you around. A muzzle brake doesn't help much, since the brake works immediately as you fire, then some milliseconds later the bolt hits the back of the receiver and you get a thump.

Another note about the SCAR, gen 2 pmags do not drop free and need to be modified just slightly to prevent the bolt stop from riding up. Gen 3 pmags work great.

However, if I needed a straight up combat gun to fight space aliens, the SCAR would be my go-to. But if the threat consists of robots, dinosaurs, or robot dinosaurs, I grab the HCAR.

>>107603
Didn't Tromix do that like over a decade ago?

The FN was nice.

Whereas, I like the SCAR, I'm more familiar with the AR/M4 platform.

And the X95 felt oddly natural, and nice and short.

Ah yeah, sorry about that gentlemen. Forgot it's SFW board.

The episode on the Pedersen device is the definitive work on the piece.

For anyone that's new to C&Rsenal, check out the Pedersen device, the BAR, the Lewis gun episodes. They're fantastic.
