Vector Full Size tune up ?

[abundigas]

I got this used .22 kit for my Vector Full Size, and have had trouble getting it to run. I am considering sending the gun and the .22 kit to Vector to see if they can get it running properly. But I am looking for some advice on what else I should have done while it is there. I only want to send it in once. I am also waiting on a .45 bolt from Troy, so should I wait and send everything in so Vector can test all 3 calibers? I sort of wanted to keep it original machine gun specs,but part of me thinks I should get the semi feed ramp,model b sights,and a HK black paint job. The reason I mention the sights, is that to get the gun sighted in I had to turn the front sight up pretty far, and it is @ about 2 O-clock if the muzzel is @ 12 o-clock. But that might be trunion alignment, which may be causing the .22 kit trouble? Sorry for all the thoughts and rambeling,but any advice would be great, especially from those who have sent there gun in for this type of work..:silly

Get the .45 kit and then send it to Vector, all the other stuff is an option.

Thank you Johninocala I think you are correct, I will wait for the rest of the .45 kit and talk to Vector about having it tuned up. As for the other stuff, I will keep the gun original, unless they have to do the Semi feed ramp to get the .45 kit to run properly.

I'm of the opinion that it's not the kits but the host guns that have the problems. If you think about it, the kits SHOULD be uniform from bolt to bolt, and barrel to barrel. There isn't a lot that can be messed up. It's how these parts fit in the host gun that plays a key role in how they run.

Sounds like a trunion alignment issue which wasn't terribly uncommon with early Vector builds. Alignment isn't a critical issue with 9mm and .45acp ammo, but when you're dealing with small calibers such as the diminutive .22LR, trunion alignment really becomes a key factor. If the trunion is off just a smidgen, then the barrel doesn't line up properly and feeding and extraction issues are almost guaranteed to occur. If your gun runs well with the .22 conversion kit, I'll bet it runs fantastic with 9mm and .45acp.


I sent my F.S., F.A. Vector back for the 2nd time to re-weld the broken rear backing plate. It was returned with a note stating the trunion had been aligned. I was thinking NOOOO! The gun ran absolutely perfect in 9mm and nearly as well in .22 that I didn't want to risk ruining a good thing. I called and asked Rex about this un requested service and he told me it's standard practice to check and realign trunions on Vectors as needed even when guns come in for other services. Understand this gun also broke the original trunion welds after 500 rounds and the alignment issue wasn't addressed at that point in time. FWIW, I purchased this gun NIB in late 2000.

I'd call Vector and see if you can send the host gun along with your .22 conversion kit in for service.

If you want all that work done I would just consider trading for a RR model B. FWIW my model b runslike a top with any of the calibers I have (9mm, .22, .45acp). Over 100,000 of all calibers combined (about 30K in.22 with ZERO parts breakage). Broke 2 9mm extractors, 1 9mm barrel shot out and 1 OOB discharge that bent the receiver and ejector. Other than that she is in great shape.
