    Agreed. Add some KAC improvements and then we are done.

    The reason LWRC went propri in the first place was because of magazine and feeding issues that arise when you try and cram a true intermediate round into a beefed-up .22 rifle. 6.8 magazines are crap; otherwise Magpul never would have gone through the trouble.

    This was my train of thought.

    Every piston rifle I've been around has been amazing. Less carbon, less gas in your face...

    I really do think piston is the future of the AR.

    Get VLTOR A5 kits on M16's. If we can run FF KeyMod rails on them, the 20" barreled setups can remain viable with minimal expense.
    For M4's, Take Block II M4 uppers as standard. Consider a smarter barrel profile if we're done with using the M203 (Mod1 or Mod2 SR-15 uppers are a close second viable answer).
    Use the Mk18 as the PDW for anybody conclusively not shooting for a living in addition to another tool in the toolbox for current users as at least a MURG option.
    Run COTS ambi selectors on all lowers.

    As much as I'd like to see a standardized intermediate caliber weapon built from the ground up as a completely ambidextrous family of weapons with tool-less modular handguard/barrel capability, I'd rather focus on solving problems that can be addressed right now, the above would be able to leverage extant off the shelf solutions to solve tons of problems. Same with pistons - the HKM4 development line produced the best piston sheohorned into a Stoner platform out right now, and it's really good, but about the only pistol solution that is a new improvement for any application (mostly suppressed/FA/SBR type stuff), and just assuming that pistons isn't a discussion worth having here.

    Given the ammunition production capacity of Lake City and how much it would take to complete retool the 5.56 line I would stick with an HK 416 or the SR-15 mod 2. If those were the base models, followed by HK 27 for machine gunners one of the SR-15s fitted with an M320 GL and any other incidental weapons fitted for where their assigned role is placed. File a big contract with Barnes bullets to produce thousands of metric tons of 70gr. TSX bullets to be the mainstay bullet of every military small arm. Hell, scrap the shitty M855a1 and re-purpose its tooling for other projects and bring Barnes in to work with ATK at LC.

    More importantly, update the software from nation state fighting V1.0 to anti-guerrilla tactics V2.0.

    I''ll play...

    DI vs piston? DI. I haven't kept up with the newest Ar piston designs and what they do or how good they do it but the DI is more than adequate for any number of rounds that a soldier/marine will carry in their loadout.

    6.8 vs 5.56? Honestly I would just keep the 5.56 for the lighter weight/lighter recoil it brings to the table. Infantry do still go on long humps and they carry enough weight as is. If anything I would like to see the green tip ditched for a heaver 75-77 grain round.

    If I were to make changes I would probably up the barrel length to 16" with a lighter profile and go mid length gas. Free float the barrels and update flashlights with a lighter weight offering.

    You obviously have little to no experience with either.

    I agree. Use a similar barrel profile to the ELW, throw on RIS II's or KMR's, A5's and ambi controls. Boom problem solved.

    Is bushmaster and freedom corp hadn't messed up the ACR it had the potential to be the platform to beat, but they did...

    You do know that the military abandoned the SCAR-16 right?

    Thanks. In fact I do...

    The OP asked of my opinion and I gave it. As an owner of a SCAR and a 6920, I believe I'd be more quick to rely on the piston platform because of how I've perceived its performance.

    Feel free to disagree with me, but to suggest I'm not experienced is unfounded.

    In my own personal opinion my go-to-war rifle would be piston-driven. Likely a HK416. Especially when I don't know the conditions I'm going to be in, I want a rifle I'm comfortable trusting.

    This is a poll, after all...
