Hi Does anyone have own a H&K MP5 SD .22 LR? I know this is the one that UMAREX makes for H&K and that it is the only one that locks back when the mag is empty. I am looking at buying one and would love to hear if people like them.

Don't have any experience with the H&K, but I'm curious - are you aware of the GSG-5 MP5 clone in .22LR?  It locks the bolt back on an empty magazine as well.

I just got back from Ramsey's in Roxbury and they had the GSG and the were nice, had a rail too. Do they lock back? I thought the salesman said no.

 

Have you tried the GSG one? Do you think it's better?

As far as I can remember, the 9mm MP-5 didn't have a bolt-hold open, and the magazine didn't drop free either.

I've shot the GSG 522 and i thought it was a very nice rifle for the money. it has the looks and feel of an MP5 and is very "tacticool" the guys at the range got a kick out of it. I didnt keep it very long as i ended up with buyers remorse and wish i had gotten something else. IF my son was old enough i would have kept it for him. For the life of me i cant remember if the bolt held open. Shooting it with the Iron Sights was fun. I don't think you would need a red dot on this rifle but each to his own.

 

Over all i liked the rifle. The only part i didn't like was the way the stock attaches. A single Polymer screw pin. no matter what you did the stock would wobble a bit. If i had kept the rifle that would have been one of the first things i fixed.

I have a GSG5 and as long as you aren't using a magazine with weak springs (*cough*pro-mag*cough*) the bolt is indeed held open after the last round is fired. 

 

The magazines/springs that are sold by ATI (american tactical importers) are good to go.  I also use promag magazines that are blocked to 15 rounds, but I replaced the pro-mag springs with ATI springs and they work much better.

 

IMO if you're considering a GSG-5 you need to consider two upgrades for it as "mandatory":

 

- Upgrade some the of fasteners and blue loc-tite them to prevent them from coming loose, especially the ones holding the bolt together.  Get this kit:

(also strongly recommend the push-pin upgrade kit: http://rrages.com/pins/net.htm )

 

- Upgrade the stock to anything else but what comes with the gun.  The plastic stock that comes with it is thin and hollow plastic, wobbles and *will* crack on you at some point.  I replaced it with an actual MP5 stock and it was a huge improvement. 

 

Rrages.com used to sell them but doesn't have any in stock at the moment; I bought mine off of gunbroker, and I see one is available as of this writing:  http://www.gunbroker.com/Auction/ViewItem.aspx?Item=355001269.  That will fit the GSG-5 with a bit of grinding, slightly enlarging the pin hole in the receiver, and using the HK push-pin like the one rrages sells.

 

Also, fair warning, cleaning the GSG-5 is a pain - the case splits apart in two halves and offers lots of opportunities to lose small parts.  Take-down and re-assembly is a challenge the first few times you do it.

 

(I'm not a shill for rrages, but they are a reliable source for these parts).

I've heard good things about rranges, but haven't ordered from them yet...I need a new stock, cause as mentioned, it is pure crap...I have airsoft guns with better/more solid stocks...  Word is it IS an airsoft gun stock on the GSG...

 

I have a GSG522SD - it does lock back.  Maybe the clerk was talking about the cocking handle?

 

Gun is fun to plink with.  I find it reasonably accurate.  Looks badass and I had fun with it when it was working properly...

 

Issues... (besides the stock, those retarded 'pins' they use, and the screws needing loctite)

First thing I encountered is the spring for the bolt catch is prone to falling out on disassembly.  I put a little thick grease that holds it in place in the opening, and it's stayed put so far...

 

Google "GSG5 light strikes"

Eventually these guns seem to develop light strikes.  Mine did with a few thousand rounds through it.  Disassembly down to individual components of the bolt is a PITA, but once you learn how to (also somewhere in the google results), it's doable in under an hour.  I contacted ATI after mine developed the light strikes, and they sent out a new firing pin and firing pin spring for free, though I have not installed those yet.  A common fix is cutting the firing pin spring 3-4 coils (I did 3) and it seems to have worked for me so far.  I still have had a few light strikes after doing this, but it may be ammo-specific.

 

I have a feeling some ammo uses a harder case than other brands, so that could be the cause after the 'fix'.  I'll be going to test this soon with some cheap bulk ammo, which may work better anyway...I was using some 1700fps Agiula ammo.

 

 

So...it's a fun gun...gets some looks...shoots pretty accurately...but a pain in the ass to clean and maintain.  Even if you maintain it well, there is the potential for light strikes in the future...  All that said...I'm happy enough with mine...I kinda feel like I spent more on it than the gun is worth...but I still like it.  For anyone interested in one, I would suggest doing research, and factoring in a new stock, some screws, and pins into the cost.  (I also got the spare parts kit, to make it look like an MP5 again, instead of the post-lawsuit crap they all ship with now).

That's a lot of good info. But it seems like after you spend all that money on fixing the GSG you might as well have bought the Umarex. Though if ding is proving to be difficult. I found plenty of the GSG but no one seems to have the Umarex. Anyone know where I can find one that's in NJ? I did find one on line but it had a collapsable stock.

The Umarex .22LR rifle says H&K MP5 on the receiver.  If I were you, I'd go with the GSG.  Just sayin'.

Oh that does change things. I can see that being banned by name these days.

 

Then my next question about the GSG 522 is where in new jersey can I get a good price on it. I felt Ramsey's had a high price compared to what I was seeing online.

 

The light weight aluminum version was $408 and the steel version was $469. And for those who own one which one did you get? I like the steel one because of the strength and more of a real feel to it. But the lightweight seemed just as well built. And I think my wife would like that better.

Correction the lightweight one is a polymer receiver.

I forget what I paid, probably around $380 two years ago...sure you can get one online cheaper, but factor shipping and transfer fees, that will likely add $65+ to the cost.  Ramsey tends to be a little high, but usually not excessively...  Sometimes they are lower than other places...so who knows...

 

Mine is at least partly a metal body...no idea if they make one with more metal...but I'm fine with the weight of mine. 

 

You could get the collapsible stock one shipped to a FFL who does modifications.  I'm kinda thinking I wanna get the collapsible stock for the look, though cheap ones probably rock back and forth as much as the cheapass solid stock.
