    This i have problems with, I have seen enough lwrci's have problems with piston and spring cups failing under low round counts to not have great confidence in their product. While Colt is not perfect by any means, there is not another american company out there with as much combat record than Colt. And the LWRCi is not the same piston design as the AK, the AK uses a long stroke set up vs LWRCi's short stroke, and most importantly the Ak's carrier rides on RAILS. If someone could figure out how to engineer the AR's bcg to ride on rails then i think we'd have a winner.
    Haha no, I do not work for any manufacture, I just have experience with many companies & types of firearms, & I don't need to be told how an AK or AR works, I own both, & am a completive shooter as well as a ex Legionnaire & Vet. of Afghanistan.

    I think everyone can agree that LWRC would be more than happy to take your money. I don't see why Colt needs to be chastised for not living up to irrelevant expectations.

    I don't know for sure, but the "hybrid" system was mentioned in the context of Colt's new monolithic uppers with the hardened steel regulator sleeve, which performs the gas regulation function without being affected by change in aperture diameter of the barrel's gas port. This was a feature of the APC piston system, and I think the hybrid was a DI mono upper with this sleeve.

    I ask again when was the last time you saw an AK-47 barrel fall off? its held on by the same type of pins as the 6940P uses in its carrier key.

    as good as LWRC is they wouldnt be the new Military rifle either, hate to say it but a .1% increase over a good M4A1 doesnt warrant the double to triple price tag. just because LWRC couldnt make a good 2 piece carrier doesnt mean others cant. i mean cmon a dovetail and 2 screw??? that was meant to fail, 2 hardened steel pins that have a shear strength of 600+lbs that are pneumatically installed wont fail.
    Are you an engineer for Colt or were you on the DEV team of the APC? You know the exact pins Colt is using, what materials they are made of & their breaking strength? Because that is a manufacturing secrete of Colt, if they put out everything you claim to know then anyone could go low budget & make these "shear strength of 600+lbs" carriers. The thing is you don't know how these will hold up to mass use, the only thing that is fact is how a one piece carrier is stronger than a two piece design. When was the last time you've herd of or seen a one piece carrier fail?

    To say something as ridiculous as "as good as LWRC is they wouldnt be the new Military rifle either, hate to say it but a .1% increase over a good M4A1" that's a joke, you're saying a LWRCi M6A2 is a .1% increase over a current military issue M4A1? They don't even compare & it's not just LWRCi, H&K is also a 10X better more reliable rifle than a DI M4A1... You're clearly lacking in knowledge in combat rifles & what makes them a more reliable system, it's okay it comes with experience that you don't have.

    ummm.....excuse you? I think you need to back down a little bit. you being in the military doesnt mean you know jack shit(not saying you dont know stuff read below)

    I have enough friends in the military who say the dumbest shit I have ever in my life heard about small arms to let me know just cause your in the military doesnt mean you know much about firearms.

    whats so far fetched about the part in blue? its been proven time and time again that if they offer any improvement its basically a few thousand rounds more parts life. nothing worth the double to triple the price.

    I want you to prove to me the HK416 is 10x as reliable as the M4A1.......I'm waiting.......you cant.

    also everything I have seen has shown LWRC is far from perfect, especially in Afghanistan and Iraq.

    I talked to Ken Elmore and he told me the material of the pins used and judging by their Diameter(diameter of the carrier key holes) they should have a shear strength of around 4,000lbs.

    now lets try to keep this less like TOS and more like M4C and try to stay on topic and get less insulted when someone doesnt praise your favorite rifle.

    fact is Press-Fit Pins wont shear like you seem to think, they are an incredibly durable way to mount things, again the AK-47 uses them in their barrels.

    LWRC does not have quality over Colt. I was in a Pat Rogers class when he had 3-4 test LWRCs, 2 of which would not go 10 rounds without a malfunction. The malfunctions had nothing to do with the carriers.

    I remember a time when this forum and other forums were overrun with posts from people whose LWRCs would not run.

    Lets not forget the DEA in Afghanistan who stopped using LWRCs due to reliability issues.

    And what about their REPR that did not work with any magazines.

    LWRC may have gotten better over time, but there is no way I would take them over a Colt DI gun.

    At this point the Colt 6940P is an unknown to me. I have not taken a close look at it, and it may indeed suffer from the issues that you have pointed out.

    But LWRC's track record is anything but golden and they have had enough issues in the past to distrust them in the future.

LWRCi learned threw trial & error first using a staked strike face, then dovetailing & staking & still having strike faces come loose & breaking, since they have switched to a one piece design they have not had any issues to my knowledge, as well as on my own LWRCi M6A2. If LWRCi had a larger manufacturing plant & more workers that could put the same quality in to the IC they would be the new US military assault rifle. As for AK's have you ever herd of a problem with a barrel coming loose or breaking off at the trunnion since 1946? There are over 170+ million AK & variants around the world, it's a PROVEN system. A two piece carrier for a piston op AR & even DI AR's is a WELL know issue, that is why Colt is one of the only manufactures to make one.

    I don't have a favorite rifle, I have favorite rifle(s), as for the pins so far you have said 3 different breaking strengths & it keeps going up, is it going to be 2K or 3K lbs next comment? Also i'm not IN the military, I live in the states, it would be very difficult to be in the French Foreign Legion, I am an EX Legionnaire. I am also a life time shooter, I know more than enough about firearms, you can ask all your military buddies, being in the military doesn't mean anything, people who know weapons is because it's a very large part of their life, not because they are military. Once AGAIN I NEVER said "shear", I said "FAIL", most likely come loose & I am well aware of how AK47, AK74 & other variants barrels are mounted. Is it that hard for you to swallow the face that you are wrong, that a one piece carrier is stronger than a two piece carrier? (no matter what kind of pins are holding it in place) deal with it, it's fact. As for LWRCi & H&K I was naming both not just H&K, as soon as I find the magazine of how many more rounds an LWRCi can go with out cleaning or failure than a standard issue DI M4A1 I will post pics & the numbers I have from LWRCi's IC as it passed the IC trials torture tests ect. minus manufacturing enough units.

    @sinlessorrow:

    Why are you claiming that the M4 needs to be replaced over on LF and HKPro, whilst you are adamant about it's superiority here?

    Just wondering, as comes across as a bit inconsistent.

    Also, what does HK's, LWRC's, AK's and what not have to do with the Colt LE6940P?

    All this posturing about shear strengths, or lack thereof, failure points etc is purely conjecture. Can anyone point to a failure of this specific 2-piece carrier design from Colt, for the piston and op-rod?

    And who cares how many rounds a gun can shoot during an endurance test? That is a spec requirement, and gives an estimate on how the gun performs under extreme circumstances. No gun is designed to run dirty or dry over time, under normal use.

    i was giving examples, the cheapest Pins i could find were rated for 600lbs, the more expensive ones are rated for 10,000lbs at 1/4" in diameter

    a press fit pin will not come loose, they are generally bowed in the center this basically proves that the pressure and design will make them near impossible to come loose, its not a hard concept to grasp

    well while you go looking for that I'll post my pics and information, also see Ed L's post, the LWRCI dont seem to do great in real combat situations.

    http://www.slip2000.com/blog/s-w-a-t...ine-filthy-14/

    Arctic1 I was using the AK-47 as an example of how press fit pins will not shear or work them selves loose, the AK-47 uses them in the instillation of their barrels.. I also am not saying the M4A1 is superior just that the HK416 is not 10x better. to make a statement like that without proof is pointless.

    not sure about LF but I am on HKpro, and my main reason I mention replacing the M4A1 is purely from a if the PiP will leave us with a standard M4A1 the IC offer a slight upgrade in the fact they have modern parts.

    LWRCi defiantly had many issues in that past, that why I mentioned that "LWRCi has learned their lesson with two pice carriers" I've an M6A2 that I have yet to have any type of failure & I am a completive shooter & have attended many advanced carbine classes that are multiple days long, that last the entire day, shooting 1,000's in a in that time period with out failure (unless it's a failure drill & I manipulate the failure myself). They are still used by US Army's OD-D & I was unaware that the DEA had stopped using the M6A2, LWRCi clames that the DEA FAST Teams still use their rifles.

    I have 30+ some rifles, I just use LWRCi as an example because they have have the most widely used piston operated AR of any military & civvi piston AR, that means they have had the most use, the most experience, failures & have had the years to get feedback to fix the issues that they have very successfully.
