1/12/2023 0 Comments Stove pipe gun jam![]() I'm just not a fan of this aftermarket hand guard configuration - where you go from 3 rails and 15 screws to 2 rails and 4 screws.Īdding to this post as I have also posted in the Arfcom thread as well.Īfter only 2.5 weeks into its second trip to CZ I received notice that my pistol's warranty work was complete. as per CZ) and nord lock washers (available from Fastenal) as the originals get stretched and jinked up from disassembly / assembly and locktite residue. I'd use new screws (torqued to 65 in.lbs. Other than that, before you send it back to CZ, you might reassemble the gun in the original configuration with the OEM hand guard and see if it works better or not. Can you get a bore scope and look at the gas port from inside the barrel? I'm wondering if maybe the gas port / gas block are misaligned / misshapen or maybe drilled too small? Seems like gas gets clogged up and it stove pipes, gets burned clean with subsequent rounds and then starts the clogging / stovepipe cycle again. Is it certain magazines or ammo that is worse for this? Looking at your video, it appears that the first rounds are barely getting ejected before it stovepipes, subsequent rounds appear to eject normally, then suddenly stove pipes. This bren has roughly 400 rounds through it at this time, I'm going to contact CZ about the pistol and see if they can take another look at it. I'm also going to add a picture of the wear on the front of my ejection port for all to see, I'd like to know if any of you have the same wear?Īlso here is a picture of a spent case, this case barely made it out of the chamber when fired. All in all I shot 100 rounds with one stovepipe. The next magazine was loaded to 30rnds and unfortunately at the tail end of the mag I had a stovepipe, I would guess right around 75 rounds into the session.Īfter clearing the malfunction I burned off the remaining ammo I had without a hitch. I then loaded a different magazine with 30rnds which the pistol also made it through. The pistol made it through the first magazine of 20rnds without a hitch. I received the pistol yesterday morning and was lucky enough to slip away to the range to quickly run 100rnds through it for a test fire. When I received the email stating what had been done to correct the problem I was not very optimistic that the issue would be fixed, however I figured I would give it a shot. I was having stovepipe malfunctions at a frequency of roughly 1 per magazine. ![]() Well, after 5 weeks I received my 9" Bren 2 back from CZ. I also tried both gas settings with no change in performance The original video I took is here:įor the rest I'll just copy my update from Arfcom. The pistol would have these malfunctions with all the ammo I was using, Wolf FMJ, HP and Golden Tiger FMJ. ![]() Many times the empty case was flipped 180 degrees and wedged between the chamber and bolt while attempting to chamber a 2nd round. On average I would get 1 stovepipe per magazine. My bren 2 was having multiple failures to eject and stovepiping fairly often. Perform proper maintenance, and your guns will have fewer malfunctions, improved reliability and a longer life.Other users had asked for more info on my pistol so I figured I would post here as well. One final tip: Cleaning your guns and tools after you use them is a good habit to have, because dirty tools won’t properly clean your firearms. Less often, it’s the ammunition the causes a stovepipe, with the culprit usually being handloads. Keeping your gun clean and well-lubricated is the usual cure for cases of multiple stovepipe issues that aren’t due to a shooter’s form. A bad grip, with weak wrists that fly back when firing a pistol will keep it from cycling properly. ![]() Proper grip and proper maintenance will help prevent stovepipes. Tap the bottom of your magazine firmly to make sure it’s seated rack the slide to the rear to feed a new round into the chamber, and assess downrange. ![]() There are a lot of ways to fix this (both correctly and incorrectly), but here’s one tried and true method-the familiar Tap, Rack and Assess. This malfunction was dubbed stovepipe in the 1920s-when the use of semi-automatic handguns was becoming widespread-due to the resemblance of the exhaust pipe on top of the wood stoves popular at the time. The case ends up caught between the slide’s breech face and barrel hood as the slide attempts to close. In semi-automatic pistols, the term “stovepipe” describes the malfunction when the fired case has not been properly ejected from the port. ![]()
