Indent on the primer like a light primer strike, indents or dings to the base or rim of the cartridge, or indents on the side of the case (and, if so, where)? (2) Is this from a fully loaded magazine, or a partially loaded magazine? (3) Are you using a standard weight carbine buffer or something heavier? (4) Is this shooting 5.56/.223 or a different caliber? (5) Have you tested this with different magazines?Docenthttps://www.blogger.com/profile/13573255956484552163noreply@blogger.comtag:blogger.com,1999:blog-2195077991229481958.post-26326069667239833772021-04-29T09:43:32.289-06:002021-04-29T09:43:32.289-06:00New ar pistol build 7.5 inch barrel is fires 2 rou...New ar pistol build 7.5 inch barrel is fires 2 rounds and always the third had the round jamming with indent marks on the unspent round.<br />Removed gas block to see powder imprint around gas port , which was not perfect but very good. Tried to achieve a more precise positioning of gas block. Still first 2 go off fine and third jams.Should I try a whole different buffer and spring of same type? All parts are new. I am presuming the packaging says for carbine use is correct.<br />Comments please Vinny C.https://www.blogger.com/profile/05310685995210282717noreply@blogger.comtag:blogger.com,1999:blog-2195077991229481958.post-28377119709550270762020-09-19T12:32:11.218-06:002020-09-19T12:32:11.218-06:00In Greg Ellifritz's 9/18/2020 Weekend Knowledg...In Greg Ellifritz's 9/18/2020 Weekend Knowledge Dump, he links to an article about problems with the M16 in Vietnam that reported extraction problems due to bolt jump, the solution being buffer weight and using powder with a different pressure curve.Docenthttps://www.blogger.com/profile/13573255956484552163noreply@blogger.comtag:blogger.com,1999:blog-2195077991229481958.post-72915461053842117112020-09-18T11:49:13.210-06:002020-09-18T11:49:13.210-06:00I am having the exact same problem with an 18 inch...I am having the exact same problem with an 18 inch aero upper that I just bought. I am using a rifle length gas system and it seems to only work with federal lake city 556. Every other ammo I tried (mostly 223 but also 62 grain 556) has resulted in all kinds of short-stroking type failures. I am using a new BCM bcg (better extractor?) and heavier, higher pressure ammo next time to see if it helps. bobhttps://www.blogger.com/profile/10535022102133213362noreply@blogger.comtag:blogger.com,1999:blog-2195077991229481958.post-60204769625146917872018-08-09T08:56:26.089-06:002018-08-09T08:56:26.089-06:00Thanks for your comment.
