Some hard truths from ACTUAL real world testing of AK's

[MrPlink]

Do you mean the aluminum sheets formed with a drop hammer?? because that is still not forging,

Forging is starting with a billet and beating it into shape and it takes a wee bit more then five tons to do it,

All you were doing was a proprietary process that Rohr developed in the 40's and it ain't forging. it's still sheet metal work, It's the only way to get the sheet to form in complex shapes they were making but it was still a sheet or a panel

Now if you were to sight the Ti parts and the SPF process to form those parts sure that's a whole other ball game
.
Fact remains sheet metal work and rivets are strong in the correct design and correct application.

Pwnd!

One of my best friends is a senior engineer at a higher end machine shop in the bay area. They make very fancy high-end stuff, and also do the welding for the Tesla motors. Anyway, we talk about guns all the time, and he always gives me a hard time about spending money on "useless" features or items when it comes to guns. For example, cast lowers for ARs in his mind, are better than forged. Stamped AK receivers are better than milled. He has many different reasons, factors in types of usage, and costs to come to his conclusions. So reading this information doesn't surprise me, nor do many of the posts... hahahaha

Whats a WASR?

Ron,

If you can answer, which piston ARs did you guys have? Any PWS piston ARs?

[saki302]

We did away with all of the AR piston platforms with the exception of the HK MR556 [B]BUT[/B] the factory barrel started to keyhole at approximately 10K rounds.

I've had a couple piston uppers (and one gun) over the years- the only one I have left is an MR556 upper. None of the others broke, but the HK design is the only one I liked from a mechanical standpoint.

The MR556 barrel is not chrome lined, and probably (well, definitely, now) won't hold up to high rates of fire without cooldowns.

PS- in no universe is a cast AR-15 receiver better than forged. Well, it's easier to mill and machine, that's about it. They do work fine unlike the plastic ones

Well In certain applications I want a bare bones platform, no bells, no whistles, No BS parts that do noting but empty your wallet.

Now on the other hand I'm also a big fan of pure custom rifles and I don't mean Tactical build ups those are not custom rifle in my book.

I mean like a H&H double rifle, or a Rigby bolt gun, Something built by James Anderson, Nick Hughes, Shane Thompson and the like those guys are still living and are doing very top notch work. I've had the great privilege to collaborate with them on some projects doing some welding and machining they were not comfortable with.

See that's the thing I don't think anyone has run proper Stress analysis on one to show what the lower needs to be in terms of material and strength

[BrassCase]

Wow those milled receivers really broke down.

No, these didn't:
"US (Century), Bulgarian and Chinese milled receivers have yet to fail. "

So my SAM7 is GTG.

interesting data points

[holiday]

interesting information....thanks for posting it.

[PyroFox79]

Really cool. Makes me want to get a WASR even more now.

if some of you actually knew what it cost to make those comblock guns you would be super bummed paying anything over 75 bucks for one...
