One of the guys I shoot with is a retired doctor. He's very wealthy with a huge gun collection. He let me shoot his Korth and Manurhin. I didn't have the heart to tell him what I really though. They were really well made and fitted, but not the right tool for the job I had in mind.

Am I the only guy that takes their guns to a qualified gunsmith?

Is there a YouTube video out there showing you how to do this? I learned brain surgery on YouTube, so far so goody.

You're excited and that's good, but you're WAY over thinking it. The Scheel system is a drop in buffer tube. It comes with full institutions and even a cheat sheet of which springs to run for what ammo, and even where to run them. Get your gun, install the Scheel, shoot the crap out of it. You'll have fun. .

Yeah, me. Run a 135 power factor and a light and heavy spring.

Don't waste your time or money chasing the last 100th of a mouse fart. Buy the Scheel, run a 135 power factor, put in a light spring and a heavy spring, spend your time and money practicing

Nice, I've got the same gun but in five inch.

Thanks, you just saved me $1200 bucks

And grease it when you put it back together.

So is there any advantage to this gun over my 5" 627 PC ?

What makes it a (bug) back up gun ? It's got a five inch barrel, right?

I saw it for sale at my local gun range. The card says 99%, with the original box. Thoughts?

Lead Star has 9mm barrels on sale for $99.

Agreed, there are tons of variables. Short of having a bunch of identical rifles (with different recoil systems) locked into some kind of measuring device, it's all just speculation. And even then everybody handles recoil differently, and at some point you're chasing unicorn farts.

Stacking of tolerances? Everything is off by a couple of thousandths? .

Keep in mind guys that barrel length, bullet weight, powder and powder charge all affect how the gun recoils and feels.

I can't even spell "nug smith" I was just taking a guess.

So nothing in the last 15 years? Anyplace can have bad weather. I live in Southern California, and contrary to the song, it does sometimes rain in Southern California.

Bent ejector rod?

Yeah, you guys keep bitching and boycotting revolver matches. Be careful what you wish for, you may just get it.

Chuck, I lived in Phoenix for ten years. I don't remember it ever snowing.

Gotta be better than the Midwest? Northwest, Northeast...

Yeah agreed, who wants to go and have fun with their friends in Arizona when the weather's nice. No thanks !!

Just kidding, there is no definitive answer First a little house keeping. I'm no chaos, and I'm certainly no blowback, I'm just a guy with a couple of AR 9s, a little free time, and some 9mm ammo. I don't have any sophisticated electronic measuring devices, or any unsophisticated electronic measuring devices for that matter. The ammo I used is my standard 9mm PCC load. It's a 124gr jacketed RMR bullet in front of 3.8gr of 231. Out of a 16" barrel it's going 1140fps giving a power factor of 140. The test guns were both 16" barrels that I shoot in PCC in USPSA. The first one is a Juggernaut Tactical AR9 with a Scheel Roller Delayed Blowback buffer. The buffer has little rollers that "lock" into little windows in the buffer tube. The amount of "lock" is controlled by little springs in the buffer that push out on the rollers. It's adjustable via spring change. The second one is an Aero build with a CMMG RDB Radial Delayed Blowback barrel and bolt carrier. It has lugs on the bolt like an AR15, and matching lugs on the barrel. It's non adjustable. Both of them try to accomplish the same thing, keep the gun in battery longer. The tests were: 1. The Juggernaut with the Scheel Roller Delayed Blowback buffer 2. The CMMG RDB Radial Delayed Blowback, with a 3oz buffer 3. The CMMG RDB Radial Delayed Blowback with a 1 oz buffer 4. The CMMG RDB Radial Delayed Blowback with a 6oz hydraulic buffer The results The Juggernaut with the Scheel Roller Delayed Blowback buffer is very soft. Next to no for bounce, in fact the dot just wiggled to the right. The CMMG RDB Radial Delayed Blowback, with a 3oz buffer, is "sharp" with much more recoil and dot bounce The CMMG RDB Radial Delayed Blowback with a 1 oz buffer is MUCH softer than the 3oz buffer. Much softer. Not quite as soft as the Scheel, but pretty close. The CMMG RDB Radial Delayed Blowback with a 6oz hydraulic buffer is the softest of them all. It's like shooting a .22. No bounce, no recoil. I'm waiting on my dual weights and flat spring from Midway so I can build blowback's “Gentle Recoil” 9mm AR Project. Questions? Answers? Anybody want to buy me lunch?
