Vector Full Auto .22 Kit

[sbmania]

My buddy and I both recently received our Vector full auto .22 kits. Biggest problem for both of us was that neither gun would eject the fired round, either semi or full. Switched extractors with no improvement. Noticed that after a jam, if I removed the full mag and the jammed new round from the chamber, the old fired casing would extract every time when the bolt was manually cycled. Is it possible that the Remington Subsonics I was using have a soft primer and were firing prematurely - ie, before the extractor had a chance to engage the rim of the casing? Otherwise, why do they always extract when manually cycling the bolt. The extractor has good tension to hold the rim, at least when manually cycling the bolt. Currently, Aguila Sniper Subsonics appear to be working flawlessly, at least with the 50 rounds I had to play with. Will be buying more as soon as I find them. Do the Aguilas have a harder primer than the Remingtons, or am I barking up the wrong tree? Any other thoughts?
Also, we notice the 40 round mags (9mm) don't work well. The bolt often hangs up on the mag when travelling forward causing a FTF. The 40's seem to have some up and down play to them when engaged in the mag well, which the 28's do not. What is the easiest fix for this? Thanks!

The Remington Subsonic .22 is probably underpowered for a sub gun kit. I would try a hotter supersonic round, and see what happens. I think most people use high velocity .22's with them.

I am assuming the 40's are from Vector? Those mags were originally for another gun, and the teardrop shaped pieces that are on each side are lower. On a normal UZI mag those would stop at the bottom of the mag well. The fix is to just make sure the mag is in the catch. If you push it all the way upward, give it a pull downward till it is back in the catch and it should work fine.

Try Winchester Super X or CCI mini mag. Vector test with Winchester Super X.

JClem555 is right on the money with both answers.

If your looking for subsonic ammo, try Winchester DynaPoint. I buy it in the 500 round bulk packs at WalMart for less than $10.00 a box. It stays subsonic in the Vector kit and functions well.

Insert the converted 40 rounders to point of positive engagement and then tug down.

Try Win. Dynapoints or Rem. Golden. Both are sub sonic in my Full size SMG. Rub black magic marker all over the top of the mag. Then cycle it. Look for rub marks.

In my experience, Remington Subsonic is HIGHLY unreliable in my Uzi/22, M16/22, and Walther P22. I've bought it from four different vendors over the course of a year and it's all been the same. I experience, on a regular basis, loud ejection port noise and a lack of power to cycle the bolt/slide. It seems that the casing is undersized and allows pressure to escape around the casing (I believe this is referred to as "blow-by"). I'm still somewhat amazed that I see Remington Subsonic in advertisements placed by well known suppressor companies.

If you're looking for quality subsonic, give Winchester Dyanpoint a try. In cold temperatures, you may hear that supersonic crack. But in warm weather it's not a problem. For something that is even quieter (and cycles just as well in my Uzi, M16, and P22), try CCI Standard Velocity. CCI Standard Velocity has been subsonic down to 30/35 degrees and sounds very quiet. Keep in mind, your kit may need to be "broken in" before it'll function well with subsonic.

As for your question regarding hardness of primers. I don't see this being an issue with the Uzi conversion kit whatsoever. The fixed firing pin crushes the primer like nothing I've seen so far. Like other rimfire firearms, it is a good idea to buy numerous brands of ammunition and see what it likes best.

Remington Subsonic

My Vector 22lr kit works well on Remingtion Subsoic, I do have a factory IMI SMG so no out of spec anything here. My kit also came with a special recoil sping marked 22lr.

I've lost count of the times I've said it. Find a brand, (or two), that your .22 conversion kit likes and stick to it. I think the only constant on these kits is no two are alike where their ammo diets are concerned.

I agree with Vegas

Try a bunch of different ammo. You will probably find a couple that work better than anything else. Polishing the chamber might help too.

Best,
