    For a while there m4s were breaking extractors regularly, but I believe they have helped fix this by beefing up the relevant parts/changing spring rates/etc. Just keep in mind that a good m4 is not just an m16 that has been cut down. They re-engineered parts because of what they are talking about there.

    May want to check a thread on tacticalforums.com called "AR Deficiencies". Lots of knowledgable people chime in on all manner of AR's.

    Wait a second... I thought the M4 was flawless. Now I hear it has problems?
    I'm so confused.

    All carbine length gas systems, not just the M4, will run at higher pressures. This may or may not affect functioning in a particular carbine depending on all kinds of factors.

    There are any number of gadgets designed to reduce the cyclic rate or gas pressure in a carbine length gas system. Most of them are unneccessary in your normal 16" semi-auto carbine, though a heavy-duty extractor spring or O-ring extractor insert can provide some cheap insurance.

    Problems with the carbine length gas systems are more apparent in full-auto or suppressed guns (or guns with both) than they are in semi-auto 16" guns.

    I believe the 14.5" M4 barrel is long enough to use a mid-length gas system, which would fix any gas pressure issues.
