Apologies for what may be green or newbie questions but I am brand new to this and need some help and expertise. I have found a transferable Action Arms Model B 45 for around $20k. I have no idea what questions to ask. The salesman I spoke with believes it to be a registered bolt but wasn’t certain(the gun has to be shipped to them). If it is an RB, is that a red flag and something worth avoiding ? Is it a concern at all that it is a conversion? I see Uzi 45 mags for sale on websites but it’s unclear if those would work for an Action Arms Model. Again apologize for the newbie questions but any assistance is welcomed. Thank you all

Almost all transferable imported UZIs are conversions. The registered bolt should be slotted to clear the blocking bar in a semi auto, if it is it can be installed in any semi UZI receiver. If it isn't, you have a bolt that can only be used in the modified receiver it comes with.

.45 UZI magazines come in original IMI and aftermarket pro mags. They fit the standard magwell. IMI are rare and expensive, Promags has not the best reputation. There are a few lowers converted to take MAC10 or Grease Gun magazines but they are obvious when seen.

As Brian said, a registered .45 bolt is a one trick pony, all you will ever have is a .45 UZI. A registered receiver is much more versatile. It can be converted to many different calibers.

Hi Rtc079.

First question is what caliber is firearm? We have so far assumed that it is 45. If it was a converted model B 45 it could also have been converted to 9mm.

I'd ask the seller which conversion method was used to convert the carbine. For the most versatile conversion the blocking bar is removed. It can't be removed now. (Blocking bar = steel bar welded in on the right rear inside of the receiver behind the ejection port.) It has to have been removed when the firearm was converted. BATF considers the removal of the blocking bar to be the manufacture of a machinegun (and that's not allowed).

As mentioned earlier if the firearm has a slotted bolt it could be a registered receiver/slotted bolt conversion or a registered slotted bolt conversion. Both can work. You are limited to only 1 caliber with these conversions. The price normally reflects the slightly less desirable aspects of not having a registered receiver. At 20k, you should be able to get a registered receiver conversion w/o the blocking bar IMHO.

Enjoy,

K2

20k for a registered bolt is extremely high, especially in 45. 45 uzis are notorious for feed and chambering issues, expensive mags, and they beat the hell out Of the back of the receiver which was originally designed for 9mm. For 20k you can easily get a registered receiver, or about 17k a registered bolt gun in 9mm

I'm selling my Full spec RR by Marty Pearl. Much better deal than a bolt gun @ 20k.
Big plus for you is that its in Lantana at my dealers on an F3.
Hope this helps!!!!

Dave, if this isn't allowed just give it the old 86.
Thanks.

And it ain't a Vector!:)
I've had 2 of those POS come thru and neither one would run without EXTENSIVE work. I'd take a BG bolt in an IMI host all day long over a Vector. Yeah, I've got a real woody for them.
The 45 BG bolt I had didn't function very well. :(

My Jim Wilson converted Group Industries bolt is great, though. Never skips a beat. Price was about right, too.

I've had 7 BG bolts over the years and I’ve been fortunate in that they all ran great. I have heard that there is an occasional BG with issues. If I were buying a bolt or a Vector as a first SMG I'd want proof of life. Wait, not true, I wouldn't be buying a Vector. :) Back in the day the joke was, if a Vector said unfired, it really meant it wouldn't run (Seriously).

I've had a few of the Group bolts and they were without issue as was your experience.

Hard pass on that. UZI is way better in 9mm. Definitely get a Registered Receiver or RR. For $20K you can get an RR. And make sure there’s no blocking bar so you can use standard SMG bolts. I got a Vector Group RR which is full SMG spec. Some say the IMI receivers are better, but they started as a semi-auto carbine. If the blocking bar is still there you can’t remove it. If the blocking bar is gone, then you can bring the receiver up to true SMG spec if it hasn’t already been done. I do like the semi auto feed ramp better than the SMG feed ramp. Just cut off the restrictor ring off the top of the feed ramp. I may replace my SMG feed ramp at some point for better feeding. Runs FMJ’s just fine. But flat points or hollow points are not as reliable.

I just thought I’d throw this into the mix. I have a group industries registered bolt that I must have over 40.000 rounds through it and never had any issues with the bolt. Any issues I did have were with the host guns. I had a broken sear, a feed ramp came loose and that was on a IMI model A. All the other usual stuff like top covers needed to be adjusted. I have 2 host guns that I move the bolt around to.
