    If you're confident in your firearm, and it performs reliably, then don't make any changes. It works for you.

    As for me. This is what works. A mix of excellent materials, and parts.

    How does my experience stack up to Ken's?

    It doesn't. My experience doesn't stack up to the pros.

    Things on standard carbines that failed me?

    On higher round counts with light buffers and no cleaning, my rifle would fail to go into battery, or fail to extract, due to debris in the extractor. I was also having magazine problems due to them not being cleaned either. (Totally different issue.) and the rifle not being able to feed them properly. I think the feeding issue was also magazine related as it didn't happen with Lancer's or PMAGs.

    Basically I want to make my dirtier DI gun run better, some of these things go on my KAC gun, other things, don't need to.

    Also made them a hell of a lot faster to clean, carbon, and unburned gunpowder didn't corrode on BCG, and trigger unit.

    One reason I'm for gas block sights, as opposed to sight posts, is rust due to non-parkerization under FSBs. I don't know who does, and doesn't do this. So I stay away from it altogether. Even the LWRCi guns with FSBs.

    I'm trying to find a solution for myself for the cutoff point in heavier buffers in high round counts. Where debris makes it so that the BCG cannot be pushed all the way back, and fails to cycle, and go into battery. It's been mentioned before recently, and ever since I've read it. I've been researching a solution, this has been a very recent experiment for me. Actually the last two days.

    I'm getting ready to go out and put rounds down range, to experiment.

    With a suppressed gun, these things make a much bigger difference.

    Input wanted.


    With blowback from a can you are going to get fouling no matter what the insides are coated of. Its got to go somewhere doesn't it?


    These coatings and parts you mentioned might have some benefit in high round counts without being cleaned when using a can but only someone hell bent on not cleaning their equipment would even get that far. A soldiers basic load is 210 rounds. Civi's and LE carry even less than that on their body, and are certainly much less likely to ever need to fire more than 210 in any situation. If a civilian gets into a gunfight they need more than 210 rounds something is seriously wrong, and a one in a billion type event.


    BCM has had test guns go well over 10k rounds without being cleaned. I just ran my KAC SR15 to about 5k without cleaning over a 2 month period. Lots of other people on here have done similar things.


    But for a duty or SD/HD gun it should be kept clean, and serviced regularly. That negates any need for some high dollar parts just so you can push a round count without cleaning as far as you can before you start encountering problems. If that is your end goal then go have fun burning up that ammo but its certainly not needed on a duty gun (mil, civi SD/HD, or LEO).


    For someone like the OP who is just using the gun recreationally they don't need to do squat but just go shoot, and try to improve what they can. If he was looking at doing some classes, and getting more into the tactics side of things then Id suggest a better BCG like BCM, LMT, Colt, etc. and to keep some spare parts on hand in case something breaks on him.

    The coatings are for ''dry lubricity''.

    I'm aware that the debris has to go somewhere.

    And yes I know that the BCMs will run fine, but as the gun gets older, and total round count gets higher. Like with my guns. Reliability will change.

    Also in SHTF: Sometimes you just CAN'T clean your gun.

    Also a principle of I'd rather have it, and not need it, than need it, and not have it.

    You've a very good point though, and why my modifications, are not for everybody.

    They're for me, and people who run guns like I do.

    Wow. What type of scenario do you have in your head? Like I mentioned before Pat Rogers has had both BCM, and Colt guns go over 10k, and one over 20k without being cleaned.


    Wow. I didn't know we had such a cat on here who a regular AR15 just isn't good enough.



    So wheres your scientific type testing data that shows these parts are significantly better in a real world situation? Im not talking about your SHTF scenario you have conjured up where you are going to burn through so many rounds so quickly you burn all the lube off, and are so busy shooting you just can't relube the weapon?


    You mentioned pistons in your original post in this thread. Wheres your data that shows they are significantly better than a DI USGI gun in a real world situation?


    Or do you just think these things on some very limited self testing you did? Do you have a log sheet showing the differences in performance with a variety of data points to consider?

    It's a fairly good representation of how silly this thread is getting.

    I hear folks offering experience from both sides of an argument. I don't think you adding Michael Jackson pictures helps anybody nor the discussion at hand.

    There is experience coming from only one side and a lot of non-sense from the other side

    You can lead a horse to water... comes to mind

    Never saw the need for "dry lubricity" as I don't operate machinery dry. Wet lube does more than just lubricate; it cools, cushions, allows swiping motion of clearanced parts to remove foreign matter, and protects from corrosion. "dry lubricity" doesn't do all that.

    I'm aware that the debris has to go somewhere.

    And yes I know that the BCMs will run fine, but as the gun gets older, and total round count gets higher. Like with my guns. Reliability will change.
    At which point you can simply replace parts in a DI gun.

    Also in SHTF: Sometimes you just CAN'T clean your gun.
    Bullshit. Simply bullshit. I'd suggest you peddle that crap on ARFCOM.

    Also a principle of I'd rather have it, and not need it, than need it, and not have it.

    Oddly enough, I cannot add anything in derision to the stupidity of this comment then as currently written. Which is kind of an unusual thing for me.
