Overall length with the compensator attached is about 32”. Thats with a 20” barrel.

It’s still substantially shorter than most 308 rifles with similar barrel lengths.

Note:
Compared to an m1A with a 22” pipe.

Nice! What optic setup is that on the M1A?

Slowhand · Jun 7, 2020

Wondering that as well.

It’s an ATN Thor thermal weapons sight.

Brief range report: Desert Tech MDRx(Micro Dynamic Rifle), Side eject, 20inch barrel. FDE.
5.56, 55g XM193, 84deg, 4kt wind blowing directly from target.
EoTech 552 red dot. AGC 100 yd range. No sandbag or bipod.
Took me several shots to get on steel silhouette. I didn't bring binoculars so I still need to fine tune. Red dot dot is one MOA and at 100yds my eyes were hard pressed to find the target.
Once dialed in I put the dot in the lower left corner. Not a precise target by any stretch but I was consistent. As long as I didn't rush, everything went in a 3inch circle. Pretty sure with a scope I'd be in 1.5-2inch circle. I put 160 rounds thru it. No regrets on the purchase. Bought in PA, they paid sales tax, I paid $10 shipping, and transfer fee.
Love the feel of it. Well balanced. Trigger... not so much. I'm going to look for tuning tips or a replacement.
One thing I find annoying: The nice injection-molded case it comes in accommodates the 16in barrel, but not the 20in. So a regular rifle case it is.

had my MDR in 223 out today. had it on a sand bag as I wanted to see if my zeroing needed any touch up .( when I was siteing it in the first time, I never finished because rain had moved in). was ringing steel 18 inch plates at 300 yard , 400 yards , then 450 yards. had a decent cross breeze. was shooting 55 grain wolf brass. we had small tanerite targets about the diameter of a coke can ish. ( but about 2 1/2 times the height) took 2 out at 300 yard and 2 out at 400 yards. I have to say the gun has really impressed me !! next will be trying it silenced and see how it does! :-)

Shot the MDRX 308 20” at Myrtle grove today. Only confirmed zero.

After about 20 rounds, I let my range buddies shoot it. Most shot it just to get a feel for the rifle.

At 50 yards. A 20 round mag, one hole the size of a dime. I didn’t shoot much after that. It was like 110 degrees at the range.

I have to take my 308 out again. the first time I shot it I wasn't impressed with its accuracy. but I will say I didn't have any failures of any kind. so perhaps different ammo next go around will net me better results?

@Boss94, you have 2 rifles or a rifle and barrel conversion pkg?

I have 2 . a 308 in FDE , and a 223 in black.

Think I'm gonna pull the trigger on a 6.5 Creedmoor conversion barrel/bolt kit. Just came in stock. Starting to cost same as .308 ammo...

Slowhand · Nov 12, 2020

Shipped today, arrives tomorrow. Wife visiting Dad in FL. Gave her a magazine shopping list.

Any interest in creating an MDRx group here? Or maybe a Bullpup group?

bulpup would be cool. I imagine most of it would be filled with tavar posts. I have a decent collection of bulpups including a rare 1 ( MSAR as a factory gun in 7.62x39 1 of 5 MSAR said they sold as complete rifles from the factory, and it also came with both a left and right handed bolt. they said its the only left handed 7.62x39 gun ) I did pick up a 2nd MDR in 223 a few weeks back.

SCARCQB · Nov 20, 2020

I like bullpups as well. Purchased an mdrx 308 earlier this year and I’m considering the 6.5cm conversion as well.

Going to revive a dead thread for a question...

So, I want to get a .308 MDRX with the 16in barrel but that's under MD's 29 in rule as it comes in at 27.2? So say I wanted it pinned and welded what would I need to do in order to make this happen? Do I have it FFL shipped right to a shop that does it? Do I send it to a shop of my Choice and bring it some place that can do it?

I don't really want the 20in barrel if I can avoid it as it kinda defeats its original built idea.

And what about the "happy switch"?

ok fed.

On a serious note has anyone experienced an increase in recoil with their MDRX? Mine used to shoot just fine then one day the recoil impulse turned into a 12ga buckshot/slug recoil. Also mine seems to be dependent on the Pmags with the red follower. It jams on the last few rounds with the green follower. The jams dent up the rounds so badly they look unsafe to shoot. Not to mention the amount of brass that gets shaved off.

have you cleaned your gas system? I know there gas system if it gets clogged will cause the gun to recoil harder. also reach out to them , perhaps something else is going on?
I have had zero mag issues. none of my guns are the X models.

I just gave it a good coating of cleaner. Although I can't see how this much fouling could happen so soon. I have just about 400rds through it.
