The pull weight on mine is probably right in the 5lb range, I had no complaints with that. The .2" of creep I do have issue with. It was really gritty at first but a little lube and use smoothed it out but the creep remained. I actually prefer the milspec trigger in my bushmaster to the mdr.

Maybe I got a bad one though. They're supposed to be looking at it.

Fwiw my ar's all have geisselle, larue or lmt 2 stages so I may be a little spoiled.

Review seems pretty spot on.

This is why you wait for the 2.0.  Needs an AGB or similar solution badly, and needs an improved trigger and probably a better barrel.  The last two supposedly come with the "Echo" we'll have to wait and see.

It has an AGB and an AGB isn't going to do a lot for supressed gas leakage.

Where is there official confirmation that the Echo model will have a better trigger and/or barrel?

There is none. At one of the (four) Shot Shows where the MDR has appeared, one of the engineers mentioned that a "DMR" version would be coming out, and that it would have a better trigger and/or be more accurate than the regular version. So nothing to hang your hat on.

I own an x95. I own a MDR. I own a MDR that went back to desert tech for a laundry list of problems. The trigger being a major complaint. I thought something was wrong with it. I don't own a trigger gauge. I have measured nothing. I do however know and pull all types of triggers, and have for a great number of years now.

Take it from me.... desert tech dropped the ball hard when it comes to the trigger. For me anyway.... twice.

The x95 trigger is much nicer than the MDR trigger. The MDR trigger is close in pull weight to the x95 accept longer, grittier, and way creepier. And when I say that I am speaking of the "improved" or "fixed" trigger I got back from desert tech. Truth be told I don't know if  they touched it. They took care of my other problems but when it came to the trigger all that was said was "verified correct function of trigger". It was disappointing before I sent it back and it was disappointing upon return. My word is all I have to back these statements up. So take it for what it's worth. Exactly what you paid for it. That's my experience. That's all I can share.

Edited to say: the trigger is not unshootable by any means. However it is a far cry from what we were lead to believe we would be getting.

Dont take this the wrong way Kenndapp.   But what where you lead to beleave?   Granted i never pulled a trigger on a x95 or a MDR i am still waiting on mine. But i do have a rock river arms 2 stage nm trigger in my AR's.   All i remember stated was the MDR has a two stage trigger at 4.5 to 5 lbs.

i also liked the trigger on the x95 when i had time with it.  it was much better than the 10lb trigger on the tavor.  it was decent enough to have me wondering if i liked it better than the rdb trigger.  forgot to mention, speaking to stock triggers and not aftermarket here.  that said...my fs2000 has a mushy creepy trigger, but does have a distinct break that you can actually rest on...although still terrible.  steyr aug trigger...i thought it was terrible as well.

few here seem concerned but at least you'll have an aftermarket option with regard to design it appears with the MDR.  the only other bullpups to benefit from drop-in solutions appear to be the tavors - tav-d, timney & geissele.  k&m apparently has the best trigger out of box, but believe they're elftmann triggers.  you can modify the fs2000 trigger pack with lighter springs that engage the sear, but becomes an issue if too light when dropping...hammer prone to slipping; springs keep tension on sear as it slides back an forth.  but, some have sent for modification with 4.5-5.5lb pulls.

i digressed but i wonder if the vibe would be any different here because of the expectations in knowing that they have great triggers in their precision rifles as if that legacy SHOULD have carried over to a similar degree.

I can say about my experience with my particular rifle that calling the trigger a 2 stage is a stretch at the very least.

After take up I measured ~.2" of travel(measured at the very tip) until it broke. If I let off before it broke and even if I engaged the safety the trigger did not return to the start point. There was no detectable 2nd stage to me. I'm calling it a single stage with a good amount of creep.

I donít get why DT didnít do so good on this trigger, from what it sounds like. Is the linkage longer? The technology is out there now. My RDB has an amazing trigger. I have an AR15 Colt 6920 with a Geissele SSA trigger in it, and it is awesome, and I would say that my RDB trigger is either as good if not slightly better than the Geissele. Both are two stage, or atleast the RDB feels that way, and it is a bullpup.

From what I could tell the linkage isn't the issue with mine. It was in the trigger pack itself which is good because it should be an easy fix but also puzzling as to why it's that bad in the first place.

Iím sure Shooting Sight and Geissele will come out with aftermarket trigger packs as more people get their hands on them.

Yeah I'm really hoping they or someone improves the trigger.  Just s***ty you'd have to fix it and/or put up with it given what the gun costs.

And I don't count "Adverse, Normal, Suppressed" as much in the way of adjustments.  Clearly this needs to be turned down way more, and/or something to delay unlock as it looks (as is generally the case) most of the gas is coming from the chamber uncorking early (which is common for piston guns to begin with).  But you are right, if there are other leaks they need to be addressed as well.

Iíve stated before I felt downward ejection is better because itís simpler and probably more reliable.  Itís one of the reasons I think the RDBís simple design is excellent, but itís a keltec and I donít trust it.

Well, after shooting a PS90 a ton this weekend, Iím more open-minded to the MDRís forward-ejecting design.   I always thought its forward-ejection was very interesting but maybe needlessly complicated (seeing MACís video has me re-thinking that).  

I donít have an RDB, but as mentioned before I do have FNís downward-ejecting bullpup - the PS90 (one of my absolute favorites).    This has never happened to me before, but I got some nasty hot brass burns while shooting off a table.   Again, this has never happened to me before and likely is a non-issue if wearing sleeves, but it made re-think the MDRís ejection method.   Hot brass potentially falling on your bare arms simply wouldnít happen with the MDR, so itís not a distraction you have to give a momentís thought.

I just hope the early teething issues get worked out.   I also hope the 5.56 MDR somehow manages to lose some weight.

To be fair, though, shooting the MDR offhand results in the hot brass being shot directly at your arm. Personally, I don't know which one I'd like better, since I've never fired a PS90, RDB, or MDR. Hopefully I'll be crossing one of those off that list soon!  Wink

A PS90 is awesome.  You need one!   The optic rail that comes on it is trash, should be removed immediately and replaced with a design machine mount for an RDS of your choice.  I put a damage industries picatinny rail w/QD slot for my custom savvy sniper sling.   After that, file a form 1 for an SBR and itíll be the star of the party.

Wow, I had never heard of design machine before. Good stuff. I always thought the PS90 optic situation was a bit funky, but they came up with a really effective solution.

I just hope the early teething issues get worked out.   I also hope the 5.56 MDR somehow manages to lose some weight.

I would HIGHLY recommend the RDB. The only issue with them is that Keltec put out a few lemons in the early days of the RDB, but those have mostly been resolved. If you get a recent production model, it will most likely be problem free. Those that are, tend to be very reliable. If you remove reliability as a question from the equation, the RDB handles and outperforms any 5.56 tactical rifle on the market today.

My Colt 6920 is my only serious go-to rifle only because I feel that no bullpup has shown the ability to measure up to the AR15 as of yet. The RDB would do so, if it weren't for the fact that it's made by Keltec, and as such, can never be fully trusted. If Keltec refuses to ever contract execution, QC and production to a competent company, then I wish there existed an independent agency that could accept private RDBs for testing and evaluation to confirm reliability and parts/materials longevity, and find defects/flaws and have recommended mods to implement in order to bring them up to quality.

If anyone knows of any company that does this, please let me know. I would happily send my RDB in to be inspected for quality, by an independent authority. If I knew I could trust my RDB in the same way I trust by Colt 6920, it would replace my AR as my serious go-to rifle just due to how well it handles.

There is an incredible amount of subjectivity going on with these reviews, take it for what it cost you. I don't know Jeremy personally, but I assume he is pretty good at what he does. That said I don't completely agree with everything he mentioned in his review. I'll again give you guys my opinion based off of the half dozen or so MDR's that I have shot, maybe I'm just not very picky.
Mag release: It is stiffer than average but until someone mentioned it, I hadn't even thought about it. Not a single time have I been shooting an MDR and had the release of a magazine catch my attention. Maybe I just have strong hands Wink
Gas Face: I have only shot a few suppressed AR's, both DI and Blowback. In my opinion, the MDR is no better or worse than other guns I have experienced. I have run my Silencerco Hybrid (with 45 end cap) on EVERY MDR I have shot. I haven't experienced any broken brass, nor black smears on my face or neck. I am sure the variations in back pressure from one can to another have great affect on how the gun functions. The concerns about gas settings have been heard, and it wouldn't surprise me at all if more gas setting options are made available to compensate for these variations.
Accuracy: My initial accuracy test resulted in several sub MOA and other plus MOA groups, but the average was right at MOA. I have shot several others since and it has been my experience that the MDR is reliably a 1 MOA gun. The gun sitting on my lap at the moment is accurate enough to repeatedly hit 1/2 gallon jugs at 500yds all day long. Just the other day I put it on an 8 inch steel target at 800 yards, it was not hard to keep it on target but for doping the mountain breeze.
Trigger: I haven't measured the trigger pull weight on most of the guns, but they haven't felt bad either. Some of them are a little "scratchy" in the beginning. But after some break-in, they feel pretty smooth. I would like a lighter, cleaner trigger, sure. You could say that on all but the very best guns.

I have limited experience shooting the Tavor, X95, Aug, but from what I have experienced, I would look right past them and grab my MDR.  Is it perfect? No, it has issues like any gun. But they are not significant enough to me to warrant as much apprehension and concern as given here on the BPF.  I am taking the MDR Deer hunting this weekend here in the high Rocky Mountains, shots can be anywhere from 50 yds to a mile or more. High angles, more of that cold mountain breeze, cross canyons, and quick shots are all to be anticipated. All that said, I am quite confident with the MDR in my hands. And I find myself very excited to get stuck into it with this awesome little package.

The first shot, is worth all the rest.

CBM, do you have any experience with the MDR in 5.56? I think many of us are only interested in the 5.56 rifle and want to know how it handles.
