SBR my Glock 20C

[aussiebob]

Picked up one of these the other day.
Roni Glock Pistol Carbine
http://blackdragontactical.com/go/index.php?main_page=product_info&cPath=15&products_id=80

Form 4 off to the ATF to transfer it back to me after the NFA manufacturer SBR'd it.

Got to try it out, it is way cool, and after I get another Glock 20, will make a perfect truck carbine to go with carrying the Glock 20.

Will get an after market 6" barrel for the SBR'd G20.

Have you seen or herd of a MECTEC?

Its another carbine conversion.  I was dead set on one, its on my to do list...

I have one for the 1911 frame.

Currently have it on top of my Delta frame.

With red dot easy to make 100yd shots with wimpy commercial ammo.

The advantage of the MECTEC is the 16" barrel.

The MECTEC are a blowback design, using heavy bolt and springs.

I have one on a 1911 frame too, it's pretty good. My buddy just got one for a Glock frame (in 40 S&W), with the telescoping stock; his is even better, now I have to get one too. I found with the stock collapsed, you can still mount it to your shoulder like a rifle, and get a good cheek weld on the receiver. Total length collapsed is 25.1", shorter than my 11" AR pistol. The balance is great too, good enough to still shoot it like a pistol, even one handed.

I fired this 40 S&W MechTech over the chrono last weekend, 155gr JHP's were doing 1570 fps. A 10mm version should push the same bullet to 1800+ fps. In comparison, my 11" 300 Blackout AR also pushes a 155gr bullet to a bit over 1800 fps. Granted, the 300 BLK is more suited to high velocity with 115-125gr bullets with better ballistic coefficient, but it does show that a 16" 10mm can be in the same ballpark as a small rifle.

This is a gen4 G23 frame and 22rd mag on this MechTech, next to my 300 Blk for comparison:

That's just too cool.

I like it, especially the straightforward horizontal grip you have installed--which I did not see at the MechTech site. Did you get that from them?

How does the Glock frame lock it place--is it pinned or what?
Also, what does the bolt ride on--is it just riding in the receiver tube/housing with the retractor/charging knob holding it from rotating, or does it ride on a rod or rail?

There is one little posse that snaps in the GLOCK frame to allow use with the mechtec upper.

Search it on YouTube. There are a couple good review type videos to let you see really well how everything works.

The upper slides onto the Glock frame, just like a slide.  The "Glock Block" piece is the ramp (normally part of the Glock barrel), and rests on the pistol's barrel lug block.  They used to offer 2 blocks, one regular (included with the kit), and one magnetic for extra $$.  They only offer the magnetic now, with good reason.  The regular block falls out very easy during disassembly, and requires careful positioning during assembly.  The magnetic block stays in place throughout, so make sure you get that one.  The pistol frame is locked into place by the original lock/release bar.  Disassembly is the same as removing a Glock slide from the pistol.  Very well designed, built and functioning.  They are spendy, but you get what you pay for, and they work as advertised.

I'm pretty much sold.  Wish I didn't have so many other irons in the fire.  Maybe someday.

The handguard/forend on that MechTech is just the standard part, included in the basic kit.

The bolt is round, and fits the inside of the receiver tube, and rides on the barrel. It is a big heavy chunk of machined steel, very beefy. The bolt handle prevents it from rotating in the tube.

An interesting fact about these MechTech units is the barrel is attached in the middle (at the front of the handguard) and floats free at either end, unlike most other guns which retain the barrel at the rear.

What, you have one Glock, but want two?

Must be a glutton for punishment. I love the feel of a 1911 so much better.

Actually not bad.  The Glock platform is lighter (worse for recoil absorbsion) but its plastic frame and plastic guide rod allow recoil absorbing flex (evening recoil back out again).  Plus the Glock platform has a high bore axis helping negate the effects of recoil.  Also a reason I don't mind the extra thickness of the G20 grip is it distributes recoil more evenly through the  palm of the hand.

Of course all this becomes more of a moot point if shooting mouse-fart 10mm loads.  But I don't.

[sqlbullet]

I think you mean high grip relative to bore, or low bore axis.

[REDLINE]

Yes!, thanks for correcting that for me.  I meant low bore axis.
