    For RELIABILITY:

    1. Check your BCG to ensure it is staked properly. If not, stake it.

    2. Check your castle nut and ensure it is staked properly. If not, stake it.

    3. Replace your blue extractor buffer with a BLACK one. Available at www.brownells.com

    4. Ream your chamber to 5.56 specifications. Your barrel may be stamped as a 5.56, yet if reamed, material is almost always removed from the chamber. Bushies tend to be on the tight side.

    5. Replace the carbine buffer with an H buffer. Helps with the timing and dwell time in a 7" carbine gas system.

    Your carbine is likely a bit overgassed, but it should run pretty well -- being overgassed will beat up the internals a little faster -- but just SHOOT that MFer and run it hard! Get the trigger time and roll it like you stole it!

    Can't guarantee anything, but such preemptive measure are a solid start.

    Good luck and thank you for your service.
    Thanks for the awesome reply!

    Do I see that the front sight base is shaved or a low-profile block is in place? Is there any front sight or rear sight at all? Might want to get that done so you can practice that aspect as well.
