Great review from the OP!

I picked up one several weeks ago. I wanted something fun to bring out camping that would be a hoot to shoot and was cheap on ammo. I stopped taking my big boy guns with me because I crindged every time I passed on my rifles to my buddies and thier kids. love to share my toys but watching the dollor signs fly out of my ejection port upon every pull of the trigger while in anothers hands was killing me. All though I like them, I was not a big .22lr fan so I wanted some thing that would make me smile just looking at it. This little .22lr does exactly that, makes me smile just looking at it!

I mentioned getting this HK MP5A5 to a shooter I know. He blasted the Umarex MP5 .22lr saying that he would never consider getting one and touted his GSG as being the best HK .22lr copy on the market. He said that he had heard nothing but bad reviews on it and how the GSG was so much better. I responded that he must have been reading about the Umarex Colt .22lr M-4. I understand that they had their problems but the HK version (MP5 & M-4) was improved. I asked him if he had fired or seen the HK version up close. He had no real life contact with one, Neither have I. I crossed my fingers, trusted the few reviews "I had read" and purchased one.

My Umarex HK MP5A5 runs like a champ!!!!!!! I oiled her up and put 500+ rounds through her without a single hick-up! I have no issues with the sights, they adjusted and zeroed in perfectly. I bought a couple boxes of CCI "AR Tactical" .22lr ammo. It is said that this ammo was designed for these types of rifles. It was more expensive but I wanted to give my little HK every oppertunity to run well. My buddie gave me a brick of some super old "Sears" .22lr ammo. It ate that up as well as the expensive CCI specialty ammo.

My only issue is the pencil thin barrel sleve. It would be a perfect rifle it it had a solid barrel that was more than just a liner. It is very accurate for normal plinking but how long will the barrel last is in question. I don't know what the life expectancy is on a barrel liner so I will hope for the best. My only other issue is that aftermarket parts are not in full swing yet. I bet that it will only be a matter of time before this HK version is the top seller over GSG and all the new MP5 .22lr stuff will be tooled to for it or at least made to fit both the GSG and HK version.

This rifle has peaked my interest in .22lr's. Next stop is a ProMag Murader kit for an old and well used Ruger 10/22 I just picked up for cheap! Then I just might have to save up for the HK MP5 SD .22lr. It was a hard choise A5 vs SD, I think I need both!

Jackknife:

Where did you purchase your H&K MP5 A5?

Thanks

Thanks. I live locally here in the Tri-Cities area myself. Been wanting to get this H&K also, just trying to save up the funds. Hopefully after the 1st of the year things will be right.
I'm very familiar with Dance's, have done some business with them in the past, good place. I had actually called Dance's a couple months ago and the guy I talked to acted like he never heard of that particular weapon. I'll give them another try once I get my money right. Thanks again!!!

Nice review- I've picked up one my self.

As for after market parts if you're looking:

I picked up the UTG rail which was a direct drop in no mods needed and is snug and fit - you can find it on amazon for $46

and for attaching a red dot you can use this mount which will let you co-witness a micro aimpoint or aimpoint with low-pro mount ring

happy shootin

Ok well I received the the UTG lo-pro optics rail from AIM Surplus. So far, I have not been able to get it to mount properly however. It is a claw style mount, and the claws keep slipping off as I attempt to tighten them. I will try mounting the rail again later when I have more time (preferable when my 2 year old is asleep).

I still haven't had any luck on the UTG mount. I will feel like I'm getting it, then when I switch to the opposite screw, the claw on the previous side slips off. I am considering taking the upper loose from the lower so that I can hold the claws in place with clamps so that they can't move as I switch from screw to screw.

That sounds like way too much work for something that just should just clamp on. When I get some free cash I'll order up one from Primary Arms and see how it works out.

I just engraved mine yesterday and will be SBR'ing it next week. I'll post some pics when it's done.

btw-They are a major PITA to fully take apart, I would not really recommend it to anyone.

I don't want the Emperor's prize damaged...I will test it first, on Captain Solo.

Mine doesn't.

I finally got a chance to put some rounds down range with mine today. I am thoroughly impressed. I put 150 trouble free rounds down it today and it felt great. It was very comfortable and was accurate enough for a plinker. It functioned smoothly and was all around enjoyable to use. So far I will recommend this rifle to any one.

I'm really thinking against the GSG 522 after reading this. The price though that is easy to find on the GSG is only about $300. Is the price difference worth it?

Based on my experiece with Umarex customer service I'd say avoid Umarex at all costs. It's too early to type all the saga, but I'll sum it up by saying they
make airsoft toys, not firearms and it really shows. If you ever need to send your rifle to them for repair....well...you were warned.

I think he knows that. The question above was if these rifles were worth the extra cost over the Umarex. I certainly think they are worth the extra $150 over Umarex. But that is not to say they are built really, really well. I would pay twice as much to have them really built the right way rather than cast zinc action, sandwiched in plastic.
