    On the M14 and Garand the oprod is bent, creating torsional forces that operate to the side of the line of motion, and hence the issue. The gas system on the M14 and the M60 both use a gas cutoff system that shuts the gas valve when the piston has moved a short way. This then prevents over gassing. unless the pressure cycle is extremely short. From the issue you have I can only assume Alex 'forgot' to include that when he copied it.

The '14, when loaded with wrong powder (for example the M118LR turned out by ATK as compared to the M118LR turned out by Olin), would beat the action to the point fire control pins would break.
    But the -M doesn't have a track to jump or a fire control group pins like an M14......
    So instead it just ejects WAY too hard when given some back-pressure from a can.
    Yeah, it works well when run 'in normal parameters', but it appears that use with a can isn't considered 'normal parameters'. At least without the new upgrade.

    So I have to upgrade again on top of the accuracy enhancement to get my M to run with a can?

    Current order of importance to a decision for me:
    Reliability, Accuracy, Trigger, Weight, Price.
    My -M, with scope, is well over 12. Add 9 mags, 25 rounders with 26 in them, and it's a chore just to get to the firing line, let alone lugging on a hump. Reliable: yes, Accurate: yes, Trigger: okay, Weight: I need a Sherpa, Price: mid-twos.

    MDR... DT seems to have taken their time to ensure it's reliability; only time will tell. That forward eject port will no doubt be the weak point, but one can operate the weapon with it removed, so I have high hopes. A bullpup is never going to be as accurate due to the increased frequency from moving the center of gravity reward. Faster acquisition in CQB is at odds with long range accuracy. Unless they horked something, I'm sure it will perform out to 400/500. If the trigger is half as good as the SRS, it will be sweet.

    The weight and price seem to be comparable to the -M. One thing it does that -M cannot is switch between long and short calibers, giving one more options in a single platform.

    I'm anxious to see how the gas system performs with various loads and cans. The platform is best suited for close to mid range engagements and I'll want to tune it for that.

    The first part is not always true while the second is. Definitely agree that long range optics suck for CQB and vice versa. As for accuracy, the Bullpup format when help unsupported is definitely more challenging but from a supported prone position it can be a blessing. With a bipod with magazine can act as a third support point and we, British army, found the LSW was actually a really nice option for a designated marksman with hits to 800 being pretty easy. We found shooters with the L85 were more accurate than shooters with the L1A1 and an optic so the army actually made qualifications harder. WE can argue tilting bolt vs rotating bolt lockup etc all we want but we also found the L85 to be more accurate that our Diemaco C7 and C8 rifles. Whether the MDR is up to that is something we'll find out soon, hopefully.

    Mickey, a question on if you have any experience or feedback on the 'new' Shield Red Dot that mjorin bought and I have been eyeing for some time? Thanks.

    Sorry, I haven't used one so I can't comment on it.

    If the information I dug up is correct, the L85s are 17"-20" inch barrels, and the L86 is 27". I would agree, with a 20"+ barrel supported (bipod, pack, or improvised), longer range accuracy should be no worse than any other semi-automatic in 5.56. If the info on the MDR is accurate, the 16" barrels will make anything out past 500 quite challenging. If they're using Lothar-Walther barrels (which they do on the SRS and HTI, and the price tag would suggest) then I'm confident it will perform well. Maybe they'll make longer barrel options available, or extensions so custom barrels are an option.

    I'm just looking at the physics as I have very little experience on pups. I'm not overly impressed with the Tavor SAR. It does do well in CQB, but the trigger is a chore and I would rather look at other platforms rather than spending 300+ to improve it.

    DT is renowned for two things, accurate rifles and great triggers in pup designs. I'm hopeful they built the MDR on those foundations as well.

    Yup, the L85 was unreliable but accurate, the A1 improved reliability and then the A2 made it one of the best rifles in NATO. The 20" barrel really makes it great for both CQB and range. The L86 barrel is actually too long and costs some velocity so the standard L85 is as good but doesn't come with a bipod.

    The 16 " tube on the MDR makes 5.56 a chore at range but on the 308 it shouldn't be too bad. I'm hoping at some point they offer longer barrels as a 20" MDR with their triggers could be something special whilst still only being 30" long.
