View Full Version : New to California and have some MP5 A5 questions

Hello i'm new to California from Nebraska. Im trying to aquaint myself with the very different firearm regulations out here but there seems to be alot of confusion in places, especially when it comes to centerfire vs rimfire rifles.

Im very interested in purchasing an HK MP5 A5. I believe that these are legal in CA and don't fall under the assault weapons ban here?

I have some questions when it comes to them though. My brother can get me a deal on one back in Nebraska. But he said removable magazines aren't allowed in California is this true? Would I have to buy a special CA version then? If it is not true are there limits on magazine size in California?

Now to the more tricky part. In Nebraska short barrel rifles and suppressors are allowed with a federal tax stamp and background check. Everything i've read says suppressors aren't allowed in California, but I have read a few threads saying that it is possible for someone who lives in a state that bans suppressors to buy one and register its storage location in a place that does allow them. IE i could buy a silencer and keep it at my parents house in Nebraska?

Following up that question is in regards to short barrel rifles and threaded barrels. Is it possible to get a rimfire short barrel rifle registered in California and what is the policy on threading barrels. As there is no threaded muzzle break on the A5 my hope is to be able to have the barrel cut down behind the false silencer and then threaded to accept the suppressor when i visit home. Is this possible in California?

Thanks all and sorry for the long first post!

The mp5 rimfire? Im not sure what the status is on that. Pinned stock and the fake silencer is a sleeve to cover up the minimum barrel length. I haven't seen them for sale.

GSG makes an MP5 "styled" 22lr. that is for sure legal. 10 rd mags, standard mag release. Rimfire rifles can have threaded barrels. I believe 16" is the minimum. I dont believe you can have a 14" threaded barrel and a 2" muzzle accessory (could be wrong). I think the muzzle accessory only counts towards the overall length of the rifle (26" for rimfire) Generally I hear positive things about the GSG mp5 rimfire. 16" is the minimum barrel length. It's sleeved in a fake suppressor and threading the barrel so that it can accept a silencer back to back with the fake silencer for when you visit Nebraska will not be a pleasant experience.

It will be an expensive one-off custom work.

Thanks for the reply jackandblood. I was planning to have the barrel cut down behind the fake silencer. So it wouldn't be silencer to silencer.

My brother suggested getting the GSG rimfire pistol as it has an already threaded barrel with muzzle break. So i would only need to put a stock on it and wouldn't have to mess with cutting down the barrel. But im not sure if this is legal in CA. I read something about no threaded barrels on pistols?

wow ok ill look through this.... at first when opening it up its like one of those insane joke flowcharts!

Thanks JT

UPDATE: Right at the top it says "centerfire rifles" i believe the laws are different for rimfire correct? For the most part I just like plinking so i'm fine with cheapo .22's which is nice since they seem more accepted in this state.

The HK MP5 A5 is a centerfire rifle, as it's a 9mm. If you're talking about the GSG5 22, then it won't trigger assault weapon laws. You can have detachable mags, pistol grip etc etc.

Or perhaps you're talking about the upcoming HK-branded MP5A5 clone by Umarex. In any case, as the previous posted stated, there aren't as much restrictions with rimfires as with the centerfires. Still limited to 10-round magazines though. Not sure at all about the short-barrel questions though.

Technically, yes.
Realistically, no.

In order to legally possess/own a SBR in CA, you need a CA DOJ BOF Dangerous Weapons permit. The BATFE will not approve a Form 1/4 for a DD/MG/SBR/SBS for a CA resident, unless that person has a valid CA DOJ BOF Dangerous Weapons permit.

In order to get a CA DOJ BOF Dangerous Weapons permit, you will need a "good cause" for ownership. Currently, the CA DOJ BOF will not approve a Dangerous Weapons permit unless the applicant is working in the movie/tv industry as a prop master and has the backing of a major studio.

I see, so basically no SBR in CA then. I rimfire or otherwise. i guess maybe ill look at an ar style .22lr. I was really hoping to have an mp5 copy but having a silencer to a silencer would be silly. Thanks for the info.

Johnny, California sucks these days. I am eminently qualified to say this being a 7th generation Native Of Southern California.

That said...............get used to being jerked around by the likes of Senator Dianne "30 million$ Salt Marsh Mouse"Not so Feinstein.

Cool. I thought it would be below rimfire rifle length with the stock fully closed. Now i'm interested :D

OAL with stock collapsed = 26.8" :D
OAL with stock extended = 33.8"

They are suppose to have factory 10 round magazines for it.

MSRP $555.00

Wahahaha, good news. Been waiting for this one. Hopefully there are some positive reviews of this MP5 version. The Colt copy seems to get mixed reviews.

neat stock folded meets 26 OAL.

Now umarex/walther makes the ar-15 rimfire barrels with a proprietary threading, The muzzle accessory serves to apply tension, aligning and stiffening the internals-to-outer. This threading can use an adapter to accept standard ar-15 threading for muzzle accessories while still serving the original purpose with regards to internal, external interface.

With a sleeve type fake can if the same idea is used, a possibility is to have the fake can cut to expose the inner barrel and its threads. The adaptor made by hkparts.com can then thread onto the exposed inner barrel and apply the tension needed, mated with the part of the fake can that is cut.

When in Nebraska, the adaptor can be used to to fit muzzles/ suppressors that will fit ar-15 std. thread. it will look a bit silly, but it should work. This is all assuming you have everything sorted out as far as suppressor use in Nebraska. And all of the above are just fun speculation as to possibilities and not meant as advice or instruction of any kind.

Here is a review of the Umarex MP5A5 from hkpro. I don't see any 10 round magazine versions out yet.

http://www.hkpro.com/forum/showthread.php?137183-HK-MP5-A5-.22-Rifle-Atlantic-Firearms.com

For center fire MP5, I bought in a MP5 pistol using the single shot exemption. My California FFL was Valkyrie Arms and the seller was Adam Webber of hkparts.net. The magazine release has to be disabled on centerfire. On rimfire, you are allowed to keep the magazine release.

Good luck in your quest.

On the H&K/Umarex/Walther MP-5A5...
The fake suppressor fits over the barrel and threads at the muzzle.
