    Having some failure to feed issues with my bushy. many, many, many rounds through her over 8 years. gas rings seem ok and spaced properly. thought i'd pull the gas tube for cleaning/inspection but i've never done it before.

    1. any special tools needed?
    2. no idea where to start

    i would appreciate a step by step from you AR builders out there.

    Thanks

    TACK

    Tack,

    Have you checked the gas key on the bolt carrier to make sure it has not gotten loose this can allow for gas to escape and cause your rifle to short stroke.

    Assuming all goes well with removal I would recommend just replacing it. They cost about $20 and it's no harder to put a new one back on plus you eliminate any guesswork about the old one. Aside from fouling the ends can mushroom or disfigure causing an improper seat in the key.

    I'm with Dzscubie, might as well be absolutely certain the gas key and rings are good before tackling the gas tube. The tube usually is pretty much self cleaning and normally doesn't foul up. The tip that mates with the gas key can oval out and make for a poor gas seal.

    Oh, I guess you're saying the rifle short strokes?

    Remove the roll pin that secures the gas tube to the front sight block/gas block. Pull the gas tube rearward out of the block. There is a handy-dandy little tool available to grab the tube without damaging it. However, if you are replacing the tube, feel free to mar the tube with pliers or vise grips or whatever.

    A proper-size roll pin punch (for removal) and roll pin starter punch (for installation) will make R&R of the gas tube pin without damaging the pin or block much easier.

    Regards,

    Walt

    At the risk of sounding a little skeptical, are you actually the same Walt Kuleck that wrote the books with Clint McKee, that are sitting up on my shelf here?

    Forgive my skepticism, as this is the 'interwebz', where you can be whoever you want to be, and there have been many times that people have done so.

    But if you are him, Welcome to our forum, and Thank You, for the wealth of knowledge that you bring, not only here online but in the books you have put out, too.

    Slo, I can't confirm that you have my books on the shelf...but I am the guy that wrote them.

    Honest.

    If you're into M1911s, check out the new The M1911 Complete Owner's Guide. I'm well into the writing of the next book...so if my attendence is a bit spotty, that's why ;).

    I do appreciate your kind words!

    Best regards,

    Walt

    Excellent. And yes, I will be adding that book to the collection, too. Any chance you'll be writing on the Garand, M1A, M1 Carbine, RPK, SKS, and AK47? That would cover quite a few of the toys in the box ;)

    And don't worry, we don't keep track of attendence...much. I'm more impressed with the fact that you've taken the time to post in our forum.

    We have several folks who have varying levels of technical knowledge with the AR platform, but I don't know of any of us who have enough knowledge to actually write a book on the subject. So I hope you do pop in whenever you can to offer info, suggestions, opinions, or just to shoot the breeze.

    Again, welcome.

    Slo, check my sig :). Currently in print, in addition to the two AR books and the new M1911 book, you'll find The M14 Complete Assembly Guide (yes, that includes the M1A ;)) and The M1 Garand Complete Assembly Guide. After I finish The M1911 Complete Assembly Guide a complete rewrite of The M14 Complete Owner's Guide is on the schedule.

    If you see a thread that I've missed (frankly, I'm a busy boy these days!!) but you think I should see, feel free to PM or e-mail (wjkuleck@alum.mit.edu) to alert me to the opportunity!

    Best regards,

    Walt

    Walt,

    I don't know how I missed those, but they were ordered this a.m. ;) Thanks for pointing that out. I will be looking for the M1911, too.

    And the e-mail address has been added, thank you.
