308 Bullpup War....

As far as I can tell, there are three manufacturers of modern 308 Bullpups which can be purchased by civillians: Kel-Tec RFB; Desert Tech MDR and K&M M17s. I have included photos of each below. The Kel Tec is by far the least expensive and can be had for around $1,400. The DT MDR runs about $2,500 and the K&M M17s runs $2,000.

The Kel-Tec was just too much plastic for me - I would never be satisfied with it, knowing that the other two 308 bullpups were out there. So, after comparing the K&M and the DT MDR, I went with the K&M. Here's why:

M17s was made of high quality aluminum, upper receiver and lower receiver - no plastic;

Size was just a tad longer than the MDR, but more compact than the Kel Tec.

The trigger is basically a fully adjustable AR competition trigger - really a nice touch

All three are gas adjustable, so that was not a factor

The deciding factor, however, was the bolt and bolt carrier assembly. By far, the M17s was the most robust of all three. In fact, the bolt on the MDR looked fragile in comparison. The MDR bolt looks like something the Swiss would over-engineer, and I really like that! Plus, the bolt uses extractors and extractor springs which are commonly found, so spare parts won't be a problem. Not to mention, it was $500 cheaper than the MDR. Granted, the MDR is probably the sexiest looking of all three. But, I was going for heavy-duty over sexy.

My M17s is on order and I've been told that it will be delivered before the end of July 2018. I can't wait!

1. Kel-Tec RFB


2. Desert Tech MDR


3. K&M M17s

The Tavor will be an interesting option, once it hits the States.

I picked up an unfired second hand M17s a month or so ago, very nice and simple rifle. My initial range trip with my improvised rest, so so shooting skills, cheap ammo, and scope(not the one pictured) that I have difficulty sighting with, I wasn't thrilled with the accuracy. I intend to head to the range with a wider variety of ammo this week to see if I can find something the rifle likes.

The pictures aren't the best, but better than nothing?

I've been waiting to see if the Tavor 308 would ever hit the US market. So far as I can tell, it's been promised for a couple of years now, but nowhere to be found. I gave up waiting

I will be very interested to hear how it does with different ammo. Are you comparing accuracy to other 308's with similar barrel lengths?

How does it feel, weight-wise? Is the trigger as good as other's have described? Reliability?

The trigger has some takeup, but a solid wall, and very light break, the trigger feels really good.

It is a bit hefty, the pictured setup is around 10 lbs unloaded, I don't have a very good scale for measuring though, and that scope and mount is fairly hefty. Being a bullpup, the weight does carry quite well.

I've only had somewhere around 60 or 80 rounds through it so far, I've had a few malfunctions while messing around with the gas regulator, but I think I have it set in a good position now.

As far as accuracy comparisons, my experience in .308s is with an 18" PTR91, 12.8" G3K "clone", and a pair of Hk SL7s. I can get around 2" groups with the SL7s pretty easy with the cheapest brass case ammo I can find, the PTR91 was probably double that with the same ammo, and the last "pattern" I shot with the G3K was around 7", I really need to try some different ammo with that one too.

I'm no target shooter, I collect stuff that interest me, and don't actually get out to the range as much as I want or should. I typically just use a blanket wadded up in my range bag as a rest, and fire the cheapest brass case ammo I can find. I believe the M17s is plenty more accurate than I've experienced so far, I just need to spend a little more time with it. I'll be looking forward to hearing how your like yours here shortly.

I ordered mine from K&M in March. Still haven't received it yet - they said they are a little behind schedule, but that I should receive it in the next couple of weeks. I was set to buy the Desert Tech MDR at around $2,000, until I saw the internals of the M17s. I was really impressed at how robust the bolt, bolt carrier and receivers were constructed. I also liked the AR-adjustable trigger.

I looked at the MDR's bolt and, without an abundance of cheap replacement parts, I wasn't convinced that it would withstand abuse. When I buy an expensive gun from a start-up company, I want to make sure that it is robust and serviceable. Because, we all know that either of these companies might not be here 5 or 10 years from now.

I agree, I think the Tavor 7 will be winning this field. They have built a strong positive reputation for their 5.56 bullpups. Another winning point is their price point will probably beat the others too.

That being said, that Desert Tech looks amazing. I would get that one over the Tavor if it weren't for that price tag.

Here's a comparison of the Desert Tech MDR's internals and the K&N M17s. I'm not all that impressed with the DT's bolt and bolt carrier compared to the M17s







The First photo shows the MDR bolt. The second, the M17s Bolt, and the 3rd compares the M17s Bolt to an AR bolt.

What does that little buzzard do to your hearing if you actually fire it w/o ear protection?

I don't intend to find out, I typically double up on hearing protection on anything bigger than .22LR anyway, so the shorty 308's don't bother me.

Well I got back out to the range with a variety of cheaper ammo, and some Federal Gold Medal Match 168 gr. Of course I forgot to bring a tape, or scale, and I was using adhesive targets, so I'm guestimating the group/pattern size off of the ammo boxes.

The first couple of pictures are of my super precision shooting rest, spotting scope, and rifle.

The three pictures with the FGMM were all somewhere around 3 3/8" or perhaps an insignificant greater or smaller.

The cheap Monarch ammo patterned quite impressively.

The target with just a casing on it was using Aguila 7.62X51.

All of the less spendy .308 I've tried(Winchester 147 gr, Aguila 150 gr, MEN 147 gr, Monarch 150 gr, Federal XM80 149 gr) patterns similar to the last two pictures. The rifle shoots good enough with match ammo to satisfy me, but if I can't find something for less than $26 a box with similar results, I'm not going to be doing a lot of shooting with this rifle.

And the Aguila. I didn't bother trying to measure the Monarch or Aguila targets.

The rifle had one failure to eject with the Monarch ammo, but otherwise functioned just fine.

ttarp, thanks for posting the range report on the M17s. Your "shooting-rest" looks like something I would rig. I have a couple of questions:

1. What distance were you shooting from?
2. How was the recoil and noise? How comfortable was it to shoot the M17s?
3. Did you attempt to see how fast you could shoot 2 or 3 shots?
4. Did you feel that you were getting full power and velosity from the ammo you were using; i.e. was there a ton of muzzle flash and unburned powder.
5. Would it be possible to comfortably use 30 round magazines?

1. Whoops, thats a glaring omission! 100 yards.

2. Recoil is ok, probably a bit more than an M1A, but less than an Hk RDB design. You know you're shooting a .308, but I don't consider it bad. I wear 30 NRR muffs over earplugs, and the noise doesn't bother me. Wearing only plugs, or muffs is louder than I'd like. That being said, during my baseline hearing test, the tech commented on how sensitive my hearing was, and my co-workers regularly make fun of me for wearing plugs when they don't feel the need to.

3. I didn't try any fast followup shots, I was primarily concerned with whether or not the rifle would "group" rather than "pattern" this last trip.

4. Beats me, I didn't notice any muzzle flash, but I wasn't looking for it either.

5. From a bench? No. I didn't realize there were 30 rounds magazines out there, I do have a couple of 25 round mags, and they work fine in prone position, but there isn't a whole lot of room to spare, prone would likely be an iffy proposition with a 30 round magazine.
