gregomega 929 Posted November 3, 2012 Report Share Posted November 3, 2012 finally got to take my vepr 12 out today after work. Well, I shot walmart fed bulk 7 1/2 shot. Put about 50 rounds through it. About every 5 rounds the dust cover would pop up also does not like the last round using the izzy 8rounders. It would get caught up or fail to feed at the end of just about every mag. Not every mag but just about. Wtf ever. Still happy with it. Also too my saiga 12 040 clone and my buddys s12 that I just converted. Buddy's runs great now. Mine needed to be cleaned. Way fouled up in the gas block. Went from running good on setting 1(go figure) to not running at all. Tried to unscrew the plug and it was stuck pretty good. Need a tool good. Cleaning all tonight and repeating again tomorrow. Going to inspect vepr rear trunnion for any damage later tonight. And to end the day some of the people that were there lit off some thermite: http://www.youtube.com/watch?v=aXCTNv9vt-0&feature=youtube_gdata_player Horrible shot I might add. He had a scope on his ar with a fluted match barrel. I probably could have done better with my Draco sbr. I poped off 15 or so rounds earlier and was making a cup dance on the side of the hill down where the thermite blew. Sorry, I'm not top shot or anything. Just had to comment as it was an ak-ar thing Quote Link to post Share on other sites

Koljec 37 Posted November 3, 2012 Report Share Posted November 3, 2012 About every 5 rounds the dust cover would pop up That's a little disturbing. Please keep us posted on that. Quote Link to post Share on other sites
big_sti 2 Posted November 3, 2012 Report Share Posted November 3, 2012 Seems like there have been some quality issues, glad mine was solid. Quote Link to post Share on other sites
gregomega 929 Posted November 3, 2012 Author Report Share Posted November 3, 2012 (edited) About every 5 rounds the dust cover would pop up That's a little disturbing. Please keep us posted on that. I checked the rear trunnion this morning and didnt see any damage of any kind, no markings, nothing... Only thing I can think is happening is that the choke and or the combination of the choke and gk-01 is over pressuring the system at this barrel length and its making the carrier slide back far enough to push the recoil spring back enough with each shot that by the 5-6 shot it pops it up. And when I say pops up. I dont even notice it til im dont shooting. Its not like its hitting me in the face or anything. After I was done shotting I looked at it and saw it like, oh, wtf?? nothing bad happened. taking the choke off for more testing later today to see. Might just try the gk-01 on it too for comparison. Other than the cover and the last round issue. It runs fkn great! Edited November 3, 2012 by AZG Quote Link to post Share on other sites

Doesnt look major but it deff made contact with the bolt carrier. I can take pictures if needed. Quote Link to post Share on other sites
gregomega 929 Posted November 3, 2012 Author Report Share Posted November 3, 2012 There are minor markings on my rear trunnion. Is that something I should pay attention to or be worried about. Doesnt look major but it deff made contact with the bolt carrier. I can take pictures if needed. not sure at this point. Probably not a good thing as it may lead to a cracked something or other. I know my slr106ur has had a few rear trunnion strikes with 62g and I can see dents in the rear trunnion/mounting block. not sure what the correct terminology is for it. but either way I dont think its a good thing. after that happened I cut a buffer in half and put it in. Wouldnt run reliably with a full buffer in there. but as far as the vepr goes, I might stick the other half of the buffer in there to see if it makes any difference before I take the choke and gk-01 off.

chevyman097 2,579 Posted November 3, 2012 Report Share Posted November 3, 2012 Sorry not trying to hijack the thread but here is a pic. I hope its a decent pic, never good at that. It doesnt seem like much contact but deff made some. So should I do something about this? 1 Quote Link to post Share on other sites
WUNDERWAFFEN 21 Posted November 3, 2012 Report Share Posted November 3, 2012 Wow, after reading this & seeing the above picture I checked my own Vepr. I was horrorified to see it worse than above- I actually have a circular indentation from the rear of the bolt slamming into the trunnion. I then checked my Saiga 12 that I've own for years & that had no markings. I have only fired my Vepr once so far & only put 60 rounds thru it. 45 rds of Rio buck 10 rds of Rem Sluggers 2 3/4" 5 rds of Rem Magnum Express buck 3" I have to take & post some pictures Quote Link to post Share on other sites
gregomega 929 Posted November 3, 2012 Author Report Share Posted November 3, 2012 Now that I look at mine again, it has the same as you chevy. Weird I'm just gonna run a buffer to see if that affects anything. Quote Link to post Share on other sites
chevyman097 2,579 Posted November 3, 2012 Report Share Posted November 3, 2012 Well I guess ill try a buffer out too. I never have used one though. Is there a good place to get them with cheap enough shipping? seeing as it one small part I hate to spend a ton like I have already lol. or anyone got one to hand me down?

sunnybean 939 Posted November 3, 2012 Report Share Posted November 3, 2012 (edited) I know when Ray (Saigatechusa,RamLake) was around, he said he could not figure out how the 030 was self regulating. He and a few engineers looked at and came to the conclusion that they are not self regulating. He also found that this style of gas system was much harsher than the adjustable system. His suggestion was not to run magnum loads through the "self regulating" guns. Edited November 3, 2012 by sunnybean 1 Quote Link to post Share on other sites
chevyman097 2,579 Posted November 3, 2012 Report Share Posted November 3, 2012 (edited) So in other words just 2 3/4 shells? no 3 inch? what about high brass? Pappazorro has a lot of knowledge on these VEPRs on the Russian side of things. I would love to hear from him concerning 3 inch and magnum loads. What is the typical load they use there?

49gmc 3 Posted November 3, 2012 Report Share Posted November 3, 2012 I'm a mechanical engineer and I tend to agree w the above comment about the system not really being "self regulating". After briefly inspecting my vepr 12 last night I saw nothing to lead me to beloved that it is in fact altering its function based on pressure level. I think "non adjustable" may be a more accurate description. These reports of trunnion strike back up my analysis.

thebuns1 4,323 Posted November 3, 2012 Report Share Posted November 3, 2012 I dont have mine yet, until next week, but I dont think they would have designed this thing to not handle these hotter loads. These are all still factory new guns, so Im going to at least give it a break in period and see how she runs after around 300 shells or so. Quote Link to post Share on other sites

A bit of misleading marketing isnt it? Not at all. Mine works great. have you been putting any three inch magnums in it? i ran a box of 3 inch #4 hunting loads through mine and im guessing maybe that is why i was getting the trunnion strikes. Any how I will give it a few weeks and try with a buffer. Quote Link to post Share on other sites
Mullet Man 2,114 Posted November 3, 2012 Report Share Posted November 3, 2012 The gun will shoot any ammo. But you have to understand that 3" slugs/buck and Turkey loads are much more abusive on any autoloading gun then 2-3/4" is, it's just the way it is. It's like feeding a pistol a steady diet of +p or +p+...Sure they can handle it but for how long? 1 Quote Link to post Share on other sites

Mine was like that before I ran shell 1 through it. The cavity is there so you firing pin doesn't get peened by repeatedly smacking the rear trunnion when the bolt and bolt carrier do so. Or so others have said/done before... Eric Edited November 4, 2012 by towerofpower93 1 Quote Link to post Share on other sites
