  • I have a friend that has an AR15 with a .223 wylde chamber

    Everything I've read says firing 5.56 is no problem but it was giving him problems with extraction (extractor is fine) and the casings were engaging the rifling about 1/2 mm so we switched to .223 and now it won't cycle. The carrier key is tight, the gas rings are properly gaped, and the gas tube is seating in the carrier key correctly. I worked on military weapons for 39 years but this has me stumped, any ideas?

    You probably have much more experience than I with AR's. But it sounds like a chamber dimensions issue. Have you tried checking it with go and no go gauges?

      Did you assemble this rifle yourself?
      Yes?
      Check to see that your gas block is in the proper place. If the holes in the barrel and gas block aren't properly aligned, ejection problems occur.
      Been there, done that!

          It's possible the hole in the barrel is to small.

          What's the barrel and gas system length?

            If I remember the Lylde chamber is shorter than the NATO chamber and was designed for better accuracy/ headspace control. If you are shooting NATO 5.56 the cases would be too long.

              Jimbo, you are remembering it wrongly. (Had to look it up myself)

                The Wylde will chamber and fire both .223 & 5.56Nato without issue.

                    The entire concept of the "Wylde" was to overcome a nonexistent problem.
                    I've owned both 5.56 AND .223 chambered barrels!
                    Fed them what ever was cheap, never a problem with 5.56 in a .223 chambered barrel!

                      Well Bubba... Rick357 did say the cartridge cases were getting into the rifling. That indicates to me that the chamber is too short. That's why I suggested the go no-go gauges

                        PH, his ammo may be off spec (reloads?) so I would say try some different brands. Brass that protroudes into the lands is not a good recipe for shooting.

                          Then I would suspect that the chamber may be out of spec.
                          5.56 won't extract cleanly and .223 won't cycle
                          Your "go/no-go" gauges should reveal that.
                          I can't think that much commercially built ammo would be that far out of spec.

                          Another problem could be the wrong buffer tube assembly.
                          The larger, more robust AR10 buffer tube assembly WILL fit the AR15 lower.
                          I found out the hard way an AR15 buffer tube ass'y will fit an AR10 lower! Extraction was manual only.

                            If you are putting that much case into the leade, you may have a Ohshit chamber instead of Wylde. Even in a NATO chamber, the mildest of the .223 factory loads should have plenty to run the action. If these are reloads, be sure to trim the cases back after the first firing to min case length, and dont roll crimp the bullets unless you are crimping into a groove. You'll make a bulge and the danged things will never feed.

                              Good point about the crimp, didn't think of that.
