Paintball guns use battery powered trigger/sears. Some with rocking triggers for legal full auto rate of fire.

Ohh you just gone and done it Bigfoot. Now the ATF will "invest" billions of taxpayer dollars confiscating these dangerous trigger groups that could obviously be dropped into an AR, giving them full auto capabilities.

That was our dirty little secret until you let the cat out the bag.

Mea culpa..

KelTec released info on their new bullpups. Looks to me like the first bullpups like the AUG set the pattern of 14-15" LOPs and everbody is following it. KelTec did it too by using bottom ejection behind the mag. Sheesh.

No word on the 65G chambering. http://www.thektog.org/entries/Confirmat...ifles.html

They could've had a winner. I have a SU-16 w the 20" barrel and if I ever finish this bullpup shell it will have a 13.5" LOP including a 1/2" recoil pad. The barrel screws out and headspaces on a lock nut like a Savage rifle so it can be rebarreled in 65G. I know of one that went to 6.8.

I'm excited to see the Grendel offered in the MDR. It looks like this could be the answer to the need for an AR12 for the Grendel. That is if they utilize the .308 components for the Grendel.

The all-new Desert Tech MDR: a compact AR12 16"-barreled Bullpup!

Taking advantage of the 2.850"-long magazine and beefy (read: Bolt Gun) .308 Breech --- and given the short 16"-barrel length --- what muzzle velocities can we expect from the following 6.5mm cartridges, loaded with 139-grain to 140-grain projectiles:

6.5mm Grendel - 2500 fps (approximate extrapolated velocity based on the 2650 - 2700 fps with the 139-grain Lapua Scenar from a 6.5 Grendel CZ527 bolt-action rifle, with a 22" barrel);

6.5x45mm - ?

6.5x47mm Lapua - ?

6.5mm Creedmoor - 2578 fps ("139-grain Lapua Scenar" Short Barrel 6.5mm Rifle http://www.sincityprecision.com/?p=1503);

.260 Remington - 2575 fps (approximate, based on the "2558 fps, with 140-grain Hornady, from a 16"-barreled Ruger Compact in .260 Remington" http://www.shootersforum.com/ballistics-...stics.html NOTE: See Reply #7).

In short: what 6.5mm cartridge works best, in a 16"-barreled AR12?

[SHORT-N-SASSY]

Takes standard 5.56 mags and sr25 308 mags
Calibers; .223rem 300blk 6.8spc 7.62x39 308win

pricing MDR=C .223 $2157
MDR .308 $2450

Which Caliber Do You Want This In? (Desert Tech MDR Poll started three days ago, on The Bullpup Forum)

308 - 44.4%
223/5.56 - 16.7%
300 Blackout - 5.6%
7.62x39 - 8.3%
6.8 SPC - 0%
6.5 Grendel - 19.4%
260 - 2.8%
Other - 2.8%

Combined with its other attributes, I believe the 6.5 Grendel would garner more votes, if the lower-cost 6.5 Grendel Steel Case ammo was already available.

[Keep The Change]

That is an impressive 19.4%, which beats out the 5.56 at 16.7%. That is good news for us.

Just saw this vid about the MDR from the Bullpup Forum.

It shows the ejection system better than any other video's I have seen.
Sure looks like the best thought out bullpup I have seen. Hope it actually makes it into production at an
affordable price.

[Nukes]

Will the MDR-C be available in .308?

And, here's a close-up still showing the details of the locking mechanism on the swing-open, forward-ejection chute http://bullpupforum.com/index.php?topic=5230.0 (Scroll down the Page to Reply #4, click-on the top photo).

Me likey the Desert Tech. Very nice. Too bad it will be a long time before I can justify getting one or afford one.

Thanks for the post. I had not seen the still's.
Their idea of being able to leave the port open if any problem develops is really great.
I do not for see any problem with it but a good idea anyway. My FS2000 will hold 5 empties in the ejection tube
and there has never been a problem to clear them. You can close the door on the end of the ejection tube and hold the empties in, when the tube gets full the door pops open and the brass starts to come out. I see no problem with the way they have designed the ejection system, only positives.

Dang! A working solution. Hmmmm.... I have a hankering to visit the gun store.

P.S. When you said "Just don't stick your tongue out," I was worried that it was going to be a Miley Cyrus Shoots AUG Left-handed video. Very relieved to find otherwise.

Nukes, you turd! Now I'll never get that image out of my mind!

[Nukes]

Gotta watch out for that funny bone. [grinning]

Bumped this up, so we could get a few more votes for the Grendel version.
The 6.5 Grendel had been leading the 223/5.56 but has now dropped behind by a vote.
If you have not voted yet, help give the Grendel version a boost.

OK, I voted for Grendel (but I ordered the .308).

Presently, the Bullpup Forum Desert Tech MDR: Which caliber do you want this in? Poll has the .223/5.56x45mm and 6.5mm Grendel neck and neck at 17.5%, while the .308/7.62x51mm enjoys 50.9%. And, from the viewpoint of this not-so-innocent observer http://bullpupforum.com/index.php?PHPSES...ic=1060.60, I admit I don't understand the desire for the 1950's .308 Winchester cartridge, over the ultra-efficient 6.5mm Grendel (with half the recoil), in a forward-thinking 21st Century Micro Dynamic Rifle design, replete with a short 16" barrel. Nukes, can you help?

[explorecaves]

Unless the barrel is 20" or longer the .308 doesn't make sense.

Perhaps ammo availability and/or cost may be factors?

To you it doesn't, but others don't share that opinion. Note that the UK military has a .308 marksman rifle with 16" barrel, the US Army is reportedly developing a 16" barrel version of the M110 sniper rifle, and the Mk17 SCAR-H used by SOCOM has a 16" standard barrel (with a 13" barrel option!).

[Nukes]

The 6.5 Grendel was the first (and last) time I violated my own dictum to avoid non-mainstream chamberings. Intense scrounging and acceptance of gouging allowed us to overcome the ammo/component shortage, but I am unwilling to do that again. So, ammo variety and availability demands that our first MDR will be a .308.
