Im really craving one of these, maybe someone could tell me their experiences with them or even opinions from those in the know, Im hoping for a reliable plinker. Since rifle ammo is thru the roof, I figure this would be fun and inexpensive to operate, oh, and I think its freaking awesome looking too. but thats just me

Steyr Aug might know.

I've got one. The GF loves it. I think its pretty fun. What do you want to know?

Reliable? Its an HK!

ETA: I paid 800 bucks for it in the EE for a 99%+. At the time it was the most expensive gun I had ever bought, and I questioned if it was really worth it. The only real downsides are there are next to no accessories, I still havent found a sling that works well with it, and you have to mod it out, physically alter it, or replace parts with non-HK to get anything really fun (grease gun mags, folding stock, UMP conversion). 10 round mags work well, but... 10 rounds . I got a mag clamp, but Im still about it.

I'd LOVE to get mine converted, but just can't stand to alter the gun. Squeamish I guess.

Cleaning is a pain. Getting up in there is next to impossible.

The recoil feels good though. Seriously! Something about the way it functions is similar... but different... to the "chunk-chunk" of an AK.

The "flow" of it in action is awesome, and it always gets attention at the range. Looks different from pretty much anything out there.

I love shooting it, but going through .45 ammo will cost you. Im actually looking at a Bushy 9mm carbine now because of this.

You won't see mine for sale though.

A USC (with tac light) would probably make a great home defense piece.

I used to be active at HKPro back in the day, so i have a passing familiarity with it...
The USC is a neutered ban-era weapon. Typical HK quality. Polymer receiver, extra care given to make it hard to convert to EBR mode (unfortunately) Single stack magazines, butthole stock thats molded into the lower receiver, et al.

I think that Todd Bailey clown everyone hates makes an adapter for grease gun magazines.  You can also boil the thing in RIT dye to make it black instead of gray.

p.s. 45 ammo is kind of on the expensive side, wouldn't you say? A 9mm AR upper would cost you less in the long run.

edit again: This website seems to have alot of USC stuff. As with all HK, it's on the pricey side.

Sad to say, Ive never owned an HK so i know nothing about them, are they reliable ? Accurate ? What range is it good to ( hoping its OK out to 100yrds or close to it ) How expensive are mags ? Do they hold up well ? I mean it looks mostly plastic, I have a 9mm hipoint carbine with an ATI stock, its actually a great little rifle, but it only cost 1/10 of the USC, Im hoping the cost is justified by the quality and longevity. What kind of guarantee do they come with ? Will it cycle semi wadcutters ? Do you need to use ball ammo only ?
The one Im looking at is already black

I had one... actually NEVER fired it.  Even once.  

I know motown_steve sure like's them!

I put a couple hundred rounds through one a year or two ago. It was great, I definitely want to get one of the new black ones and UMP-ize it some day. Very smooth shooting and accurate.

The black ones are newer , OK, thats good. who is motown steve ?

Ok, you're off the island!!!!

I have one, and I like it alot. The biggest thing for me is that it's quiet. Almost like it's suppressed. The drawback is that mags are expensive and difficult to find.

Also, accuracy over distance seems to be a problem too. Mine gets 10 inch groups at 50 yards. HK says that this is normal because .45 ACP is low velocity and the heavy bullet is hard to stabilize further than about 25 yards.

As far as accessories goes, there are standard picatinny rails that you can get for it to mount anything you want. I have an eotech and a foregrip on mine, and I plan on adding a tac light to it. As far as the sling goes, you can use the sling that comes with it as a tac sling to carry it horizontally. Just attache the sling to the rear hole and attach the other to the hole in the cross section on the stock and you're good to go.

I like mine and it is my go to gun for home defense.

Quoted: Sad to say, Ive never owned an HK so i know nothing about them, are they reliable ? Yes Accurate ? What range is it good to ( hoping its OK out to 100yrds or close to it ) According to HK they are accurate out to 25 yards. I actually sent mine in after I was getting 10" groups at 50 yards. They told me that was to be expected because .45 ACP is slow, heavy and hard to stabilize past 25 yards. How expensive are mags ? $50-60 each Do they hold up well ? Seem to. I've had two so far, and neither one has ever given me a lick of trouble. They aren't cheap plastic, they are well made polymer weapons. I mean it looks mostly plastic, I have a 9mm hipoint carbine with an ATI stock, its actually a great little rifle, but it only cost 1/10 of the USC, Im hoping the cost is justified by the quality and longevity. What kind of guarantee do they come with ? Lifetime Warranty Will it cycle semi wadcutters ? Do you need to use ball ammo only ? Reloads will void the warranty. The one Im looking at is already black

Reliable? Yes. Very.

Accurate? Yes. The rear sight is a flip notch/ring

100 yds? Yes. Barely. I've never shot it much further though. I've never even thought of it. Always been my "close in gun" anything out there I shoot with the .308 or AR. I'll give it a shot... you'll have to wait until after this weekend, unless someone else knows. As for accuracy out there, I can hit watermelons... most of the time.

Mags? 50 bucks or so, and hold up fine. Again, only 10 rds.

Guarantee? IF the one you are looking at was factory black (I heard there were a few imported) its lifetime! If its been aftermarket modded, you may be on your own.

Plastic? It IS plastic, except internals. The plastic fantastic!

Ammo? Never shot anything but ball, sorry can't say.

Like I said, I've been looking at some other pistol caliber carbines to avoid the cost of 45. The bushy nine, and hi-point 40 cal.

How do you like your high point?

I never liked mine and sold it.  I thought the recoil was over the top for a .45 carbine. The safety wore a hole in the top of my hand and the grip felt like holding a 2x2 chunk of wood. The 10 round mags are a pain to load and are empty too quick.
Mine was very accurate and quiet as noted above by motown. The fact is I own a HK94 which has the UMP beat on every aspect.

Quoted: Plastic? It IS plastic, except internals.

If it's not a spring or pin, it's plastic.

The bolt and recoil spring guide are steel.

I wish I could find one in black used, if you guys have a line on one, PLEASE let me know, Im looking at almost $1800 for one new.
The hipoint 9mm carbine is probably one of the most fun lil rifles I own. Im almost embarassed to say that. I paid $200 for it used with the ATI stock which really improves the look 100%. Its damn accurate to 50 yards and once I broke it in, its been pretty much trouble free, although it only likes speer and american eagle ammo, hates cci, winchester, etc. Jams like crazy unless it gets what it likes, then it just humms.
Its cheap to buy, cheap mags, cheap to shoot, and accurate and relatively trouble free. Its not bad to clean once you learn how to disassemble it.
I really cant say enough good things about it.
NOW , Im hoping to be able to say the same about the HK !! LOL
45 ammo is cheap if you reload. I go thru a ton of 45 cause I shoot bullseye competition and reload tons of it. I guess I can buy ball ammo and then save the brass and use that for my reloading purposes. No matter how you slice it, its way cheaper than $400 per 1K for 5.56
Im going to look at the web site now,
thanks guys and if you know of one used !!!!

I took "internals" to mean "fire control".

A bolt is always a bolt.  

I have one.
Except for the whole 10 round mag thing, I love it!
Shoots very accurate with a red dot scope.
Reliable as all get out.
Extremely light.
Gets a lot of stares at the range.
I wouldn't ever sell it.

I have one.  It's a fun gun and gets some looks at the range.

I've found it to be reliable with all ammo and most accurate with the lighter (165 gr.) bullets.  Drawback is 10-round mags and marginal iron (plastic) sights.

With two rails mounted; one for a light, one for an EOTech, it's a formidable home defense gun.

Thanks guys, seems like one of these will  be occupying the big gap in my safe where the rifles I had to sell to buy it were located !
I wish I could find one on the boards....oh well, new is good !

Good friend of mine has one. Its awesome. I have only shot it once or twice, however he shoots it often. I agree with Motown steve, it does sound quiet and i shot it at an indoor pistol range. I dont mind the 10 rnds. It is very accurate on 25-35 yard indoor range with irons or maybe plastics. very light. and would be KILLER black with a folding stock, verticle fore grip, Aimpoint, and of course a short barrel

I know it looks awesome with mods, but Im behind enemy lines in NY, so its gotta stay in stock form.....

in regards to the poster above re: ammo prices - that is just silly.  45 ACP (federal or aguila fmj 230 gr) is 230-250 shipped.  
9mm is what 220-240?  plus 9mm mag
options are limitted for NYers to expensive preban colts or uzi preban mags
which are also gettign pricey.

now on to the USC:

I've had two stock USC's and three converted to GG mag USC's.  None had a single malfunction, I found them easy to clean and fun to shoot.  

IMO carbines hit one extreme or the other.  I find the CX4 'push' recoil is excessive due
to a heavy bolt, while the ruger PC9's 'snap' recoil is more than it should be due to a
strong spring, AR 9mm's give you that 'sproing!', but USC's get it JUST right in terms of
how the carbine feels while shooting.  HK94's are sweet as hell, but I'll be damned if I'm
gonna clean one - now THAT is a bitch to clean.

Having said that , this time around I opted for a CAVARMs based 45 AR cause the USC
conversion to GG mags (we're in NY) is getting rare and expensive with the UMP mag
conversions gaining favor....

THERE IS a peice that can do it 'on the cheap', e.g. you don't ahve to do the whole
conversion to use GG mags.  an early conversion piece (I had one in '05) replaced just
the lwoer reciever but let you use every other part, (e.g. thumbhole stock) as normal save the internal magwell which
of course you'd have to widen.  It's ok - a monkey can do it.


If you track that piece down, it shouldn't be more than 50-75$, and all you'd have to do
is move your trigger parts into it and then open up the internal magwell on the upper.

With the 'full' conversion, you'd need a different lower that would neccesitate using (e.g.
its one piece) a true pistol grip, and you'd have to fix the folding stock as I don't even
think it's made in a non-folding version (fixing it is easy too - pop a 45 case inside the
button)....

sights are TO DIE FOR.  they line up instantly, circle in circle with a faint square rear sight
outline.  I'm not sure why i EVER put an optic on there.  That's how much I like the
sights.  But, FYI, tapco risers lifte dthe scope enough to alloow me to use the sights
under an optic, if you go that route.  I wouldn't.  It's  agreat cheekweld with a low scope
mounted.

The only gripes I had were a) the folding stock means slinging it was wierd, but a fixed
stock fixes that. b) the offhand is kinda ackward without a VFG.  there's little room for
a full grip, but it can be done.  c)full grease gun mags are HEEEEEEAVY.


To tell you the truth, if I had the disposable income, I'd get a USC and buy up mags
and leave it stock.  10 rounds isn't enough for a rambo on teh town shootout, but it IS
ten rounds of 45.  That's not too shabby.  Plus you get a BHO and that's the only way
to do that in NY.  Only problem is that stock USC mags are expensive and theirs no
cheap source.

Anyhow, I obviously like it, and here are some pics of the ones I've had (to make up
for my blathering) ....

(notice a pattern on the VFG's  - IMO the SOG one is PERFECT for the USC/UMP - the non SOG grip pics are 1) a sell pic I had with seller's grip on it and 2) when I jsut received my first one and didn't know about the SOG grips.  Fake cans were all off the EE and fit perfect.)













and as referenced, I have had the HK, colt 9mm, storm and PC9:











bu thte one I miss the most was my cavarms 45...



....so I'm building another now.

ETA: and in case you want to knwo why I'm so hot on carbines...  I started shooting at Mitchell Field - no sense bringing a rifle round there.  The addiction stuck thoguh even after moving to VA, and now that I'm back it's stronger than ever.....

I dunno if 240 shipped is expensive for ammo guys.  we're talking brass cased reloadable....  sure it was half that a few years ago but for now, I think 45 is well priced.  I get it from AIM these days.

and ETA: the part I referred to is part To Notch USC-3 see here:
www.top-notchparts.com/new_page_6.htm


I am also consdering one of these, so I'll keep you updated of whatever I find out.

top notch says they're only open M-W so no one answered there, but I sent an emial to ED at HDPS and I'll see what he sitll has on hand.

You CAN do a nice conversion, but it will use GG mags and the stock must be fixed.

I think it would be better if we wen thte other way and jsut replaced USC mags with GG mags (which I have a bunch of )

I know Bullseye shooters that consistantly group 3" or less at 50 yards.  It is one of the courses of fire.  And that is out of a 5" barrel.

HK may have been telling stories....

Hmm.

When I sent my USC back to them HK told me that their spec is for 3" groups at 25 yards and that it could easly triple at 50 yards. I get 1-2" groups with my AR at 50 yards using an EOTech and milsurp ammo, but at 50 yards with my USC and an EOTech I get minute of man.
