  1. Hi I bought a S&W .22 long rifle in AR platform and since I've gotten it brand new it is always having ejection failures. It's not every round it's about every 2-4 round it'll do it. Can somebody please help me it's driving me nuts.

  2. My magazine empty ??? don't remember , or definitely full will not insert up into the rifle on a closed bolt. It will insert and function fine with the bolt held open, mag inserted and then the bolt sent forward. It will lock back then after firing an continue to function normally with consecutive mags. What is the problem? I cant find any info on this?

  3. I just built my first ar 15. While trying to zero it in at 25 yards prone, my rounds would literally go 10-15 yards and shoot/skid across the ground. I moved up to 7-10 yards and my rounds were two feet low and way right. No matter how I adjusted my scope there was little difference in the hit location of the round. Do you have any suggestions at all? Just fyi the gun cycles fine and operates good but obviously there is a problem.

  4. right now I'm putting a carbine together from my friends parts and its going to be a carbine and I found that he gave me a rifle spring. Thanks I did not know the difference

  5. Michael, Thanks for a great set of videos. I am a new AR owner, Lever action Winchesters are my favorite but i GOT THE BUG and had one built. I wanted to take it down and check all functions and found you and I just want to thank you for the quality of your tudoring.

  6. I have a feeding issue that isn't magazine related. all different kinds of mags. the ONLY issue I have is about 10% of the time when inserting a full mag (28 rounds), bolt locked to the rear on a reload, when I insert the mag and hit the bolt release the bolt doesn't go all the way into battery. it's not head spacing, it's not buffer spring, it's not out of spec magazine release, it's not feed ramps. sometimes it seems impossible hard to insert a full (28 round) mag on a closed bolt. many times when it is hard to insert and I try to pull the charging handle, let it go to send load it, the bolt won't go into battery. when it does load it seems very sluggish. doesn't SLAM home like it should. I've replaced the lower, all the lower parts, polished the feed ramps, checked head spacing, replaced buffer spring. it's happened on multiple magazines from p mags to GI mags. the only thing I can think is an upper out of spec that has the bolt riding a little too low which is why it is impossibly hard to insert the mag on a closed bolt, or an out of spec bolt. I can't think of anything else.

  7. What a great series. Thanks for taking the time to share your knowledge. One quick question, does a pistol build (10.5" barrel) use a carbine spring or is there a separate length or coil count for a pistol? If you have time, thanks for responding.

  8. I got a very good deal on a rifle because it fails to extract almost every time, its buffer spring is only 27 coils with a mid-length gas tube and a 16 inch barrel.

  9. Mike. You should have more subscribers. You are extremely detailed which is so rare on you tube. I like your comparison on springs. On my first build(many years ago) I did not know you could order a lower KIT, so I ordered all the springs individually from Palmetto. They all came but unlabeled! LOL. I was forced to learn the hard way!
    One exception to spring length is Tubb's flat wound chrome silicon buffer springs

  10. To Southerngunner 87: The carbine spring should be at least 10 1/16" long, and the rifle action spring 11 3/4" long. With use the new springs will compress and shorten. Would take many thousands of rounds (>3K) before you should have to worry about this, and the CS (chrome silicon) springs are said to be able to last the life of the gun. As far as the hammer spring, I think the # is 4.5 lbs of force that it should take to cock the hammer. Less than this would be a weak hammer spring. This is not the "trigger weight" but the cocking weight. In both cases I think is important to look at the function of the gun. If the gun is cycling well the action spring is working well. If you are not having light primer strikes then the hammer spring is doing it's job.

  11. good video. keep them coming. how many round would it take to wear out a buffer spring? also, how man rounds would wear out the hammer spring?

  12. Great video–very easy to follow, with a lot of good info. If we were allowed ARs up here in Canada, I would probably end up with one. (They're legal here, but restricted meaning that you need authorization to transport one and it can only be fired on a government approved range.)
    The one piece of advice that I have for you is to invest in a tripod. Even an extremely cheap tripod will greatly reduce camera sway and will make the job of your camera operator infinitely easier.
