poortrader Posted July 25, 2019 Share Posted July 25, 2019 (edited) I guess I'm the only UNLUCKY one that didn't receive a complete kit. I haven't had any additional correspondence from J-Kenny after my initial contact. Updated: New One has been sent per email communication from Kenny Edited July 26, 2019 by poortrader Link to comment Share on other sites More sharing options...

021411 Posted July 26, 2019 Share Posted July 26, 2019 (edited) Just wanna make sure I have all the parts. 1. Lifter 2. Small lifter part with Kenny logo 3. Spring 4. Install tool Thats all I received today. ^ disregard all that. I watched the install video. Install took a few minutes. Looks like I might have to retweak my latch. Single feed round isn’t “tripping” the mechanism to release the bolt. The shell is not catching on the latch either.

cas Posted July 29, 2019 Share Posted July 29, 2019 It's turned my gun into a choking machine. 8 malfunctions in 65 rounds. Prior to this it had 5 malfunctions in 9 years of matches. I guess I've got some tinkering to do. Link to comment Share on other sites More sharing options...
Snausages32 Posted July 29, 2019 Share Posted July 29, 2019 I have the MOA one for my Stoeger. It takes a good while to break it in, and needs plenty of lubrication. Shells need to be loaded FAST, any slow loading will lock it up. Hope that helps some. Link to comment Share on other sites More sharing options...
cas Posted July 29, 2019 Share Posted July 29, 2019 It's not malfunctioning doing it's "trick", it's doing it during normal cycling. Link to comment Share on other sites More sharing options...
cas Posted July 29, 2019 Share Posted July 29, 2019 (edited) I learned this evening that it will jam even without a shell in it! If I work the bolt slow enough it hangs up like this. It certainly looks to me like the carrier comes up higher than stock. Combine this hitch with nose high shells and it's easy to see why it would choke. Up side so far is, putting the trigger group into another gun, it doesn't hang up. I can feel a point of some resistance, but nothing like above. Hopefully it's an issues of stacking tolerances and intermixing some parts will solve it. (yes I know they all hang up there a little there, this is more so than normal) Edited July 30, 2019 by cas Link to comment Share on other sites More sharing options...

Eagle4 Posted August 2, 2019 Share Posted August 2, 2019 (edited) Hi Marc, it's just a fact from several shooters (me include) : the auto lifter need a fast shell move to work properly. And my both M2 have the same issue : the last shell fail to feed with the "magic lifter". No issue with oem lifter or Taran lifter with same mag tube spring. When i preloading the spring with a shell between the mag spring and the end cap : no feeding problem with the last shell.

The first shell coming out of the mag tube has to have enough spring pressure to exit to the mag tube and move fully back into the receiver to disengage the the shell latch that is holding the bolt locked open. Notice who much pressure you have to apply to the bolt release to close the bolt on your conventional M2 action. With the auto lifter the shell popping out of the mag tube has to exert that pressure when the shell rim contacts the shell latch on the inside of the receiver. A weak mag spring may not propel the round far enough back into the receiver to make this happen. Link to comment Share on other sites More sharing options...

cas Posted August 3, 2019 Share Posted August 3, 2019 13 hours ago, Eagle4 said: the last shell fail to feed with the "magic lifter". In what way? I seem to have solved my hanging up half way, bolt issue by swapping around some parts. But cycling rounds by hand I'm still getting many malfunctions, often the last shell in the tube, where the shell is nose diving, or hitting below the barrel. Usually that means you need a fresh carrier spring IIRC, but mine is fairly new and still getting nose dives. Link to comment Share on other sites More sharing options...
Eagle4 Posted August 3, 2019 Share Posted August 3, 2019 Need stronger mag tube spring because some times i have some FTF with the last shell. The newest springs are harder but need find the right combinaison with my telescopic tube. Link to comment Share on other sites More sharing options...
5gun3gun Posted August 5, 2019 Share Posted August 5, 2019 Have the lifter installed and took it through its first live fire trials. Ran 100 rds through it starting at bolt lock and letting it go to lock between every quad load. So far no issues. Hoping this continues moving forward!

poortrader Posted August 14, 2019 Share Posted August 14, 2019 It's been 2 weeks since J Kenny said they were sending out a replacement lifter because my box didn't have one. Still nothing. Buyer be aware that you buying from a foreign company, for US buyers. Link to comment Share on other sites More sharing options...
cas Posted August 16, 2019 Share Posted August 16, 2019 (edited) When someone gets a chance, can they check out their gun? I'm still working on my nose dive jam. (new carrier spring didn't help) I'm working side by side with two guns, one with the factory carrier, one with the JKC. Working the bolt extremely slow, on the factory parts the carrier comes up, stays up, and the bolt pushes the shell forward. On the gun with the JKC parts the carrier comes up, and when the bolt starts to come forward, the carrier drops a little. This seems to be allowing the base to kick up and the nose to dive and jam into the mouth of the magazine tube. I know working it slowly is not the same as shooting it, but it does it slow or full speed. So I'm wondering if they all drop a little, or if something is off with mine. (by "dropping" I mean the shell is pushing the carrier down. It doesn't do it with an empty gun) Edited August 16, 2019 by cas Link to comment Share on other sites More sharing options...

cas Posted August 16, 2019 Share Posted August 16, 2019 Right as the rim starts to slide up the bolt face (or should be), my carrier starts to drop. Does this with the new carrier spring and the "old" one, which was less than a year old. Link to comment Share on other sites More sharing options...
cas Posted August 16, 2019 Share Posted August 16, 2019 By golly I MIGHT have solved it. Sitting here with my match gun and a stock M2 on my lap, cycling shells through them, watching them, feeling the difference for two and a half hours. I realized the gun with FAR more rounds through it was the far less smooth of the two. I swapped bolts thinking that might be it. Just watching them I could see how smooth the stock gun fed compared to the other. Watching the shells rise and slide (or not slide) it dawned on me. The shell stop was putting too much side pressure on the rim of the case, cause it to rarely slide up the bolt face smoothly, more often jumping out in front of the extractor. Something to do with the interaction of the new JKC carrier, the shell release lever and the shell shop. Some gentle bending towards the shells stop made the gun feed SO MUCH smoother, and the carrier isn't dropping like before. Fingers crossed.

I noticed on mine, there’s a ton of wiggle side to side and if I don’t put the first 2 rounds in with force, it won’t trip the auto load feature.

cas Posted August 17, 2019 Share Posted August 17, 2019 Dunno know if it's related... All I did was bend the end tab on the shell release lever outward just a smidgen. Link to comment Share on other sites More sharing options...
