This is the HK Factory-correct scope mount:

They are expensive, heavy, quick-detach and lockup really tight.

I dropped $125 on a MFI mount and could not get the damn thing to mount correctly. I tried a cheap UTG mount like this and it worked perfectly:

I am probably going to try one of these out soon, as I think that it will work just fine with a port buffer after some minor filing:

I just purchased a UTG Low profile mount for my PTR 91 from my work. (CTD)
I am eager to see how that bad boy performs with CAA rings and
a Burris Fulfield II.
I had a RRA LAR-8 and those 'cheap' rings were absolutely solid on that flat top.
I hope this mount fits perfectly

 

(sigh)

 

Duuuuude...

You may think it's cool, but that post is a bitch to read. And yes, I'm using the black background.

Just sayin'

 

FWIW
My PTR came with the MFI mount and it works just fine.
I have an Aimpoint mounted on it and love it.

...and I switched to the white (over red) backgound long ago ~ cause black was just too painful.

 

I'm not sure I'd spend any bucks on a cheap $32 mount from RTG, when they will not even tell who manufactured it. Esp when the $125 MFI mount doesn't work, see Jeray above. And RTG has sold both in the past.

I'd buy a real HK claw from Cheaper than Dirt, $149 for the real thing. Pick up a complete stock set for 20 bucks at the same time. You might be able to find a Fero z-24 scope if not..Then get real 30mm rings, i think $110. from RTG and away you go.

CTD .97cent alum. mags are out of stock, but the steel are still only 2bucks. And I bet Alum will be back in stock sometime.

Some guys will complain about CTD price fixing, and I don't know all the dirt they sling, but $149 seems cheap for a real claw mount. 2 buck is cheap for real HK mags, or yes maybe FMP mags or Rhinemetall mags, but they all work. I'm not going down that road, see the recent FMP thread to beat that horse.

 

The cheaper mounts that RTG sells are made by UTG. I have used the older version, that looks like a B&T mount and it worked great. I'm gonna try the low profile UTG mount at some point. The German Claw mount is probably the best option for high power optics as it is rock solid. I'm probably going to be putting a red-dot scope on mine though, and I'd prefer the light weight of the UTG mount. It's heavy enough as it is.

 

I've heard that the real deal B&T mounts are top of the line. Haven't had the pleasure of trying one myself but hopefully soon....

Does UTG stand for Utterly, Trashy Garbage, or I'm I missing something?


Hey Tyler, you rock, thanks for the great customer service.

 

Well, I have used 1 UTG scope mount and 1 UTG railed forearm, and both fit and function perfectly. IMHO, some of their stuff is good, some is not. Their crosshair illuminator is awful.

 

UTG is Airsoft products owned by Leapers of China.

 

I,m waiting on a B&T short rail , it was a buck fitty.

 

"fiddy"... a buck fiddy...

Get'cher gangsta right... else you gonna stick out like Kinte Kunte at a Merle Haggard concert.

 

Topslop1, if by "correct" you mean original, the original German one looks like this, is quick release, and requires no modification. They're usually referred to as "Claw" or "STANAG" mounts. But these also sit up pretty high on the receiver to allow the iron sights to still be used without removal. This can cause trouble getting a good cheek weld, but there are cheek rests you can get for the stock.

A genuine Heckler & Koch with adapter is $97 - just click my signature and press Ctrl + F on your keyboard to Find Claw or STANAG.

The MFI mount you posted will work well, but is nowhere near as strong. It's made out of aluminum. It will mount with no modifications, but care should be taken as the screws are known to strip out.

spqr476 posted a good guide for bedding the MFI mount which should make it much more durable. His guide is here: http://hkpro.com/forum/showthread.php?122593-MFI-Steel-Bedded-Mounting-Procedure​

​

 

Beat me to it, Andrew!

The MFI can be made very stable with the bedding procedure I used, and I'm very, very happy with how it has turned out on both rifles that I've done it to. It is a very low mount, and you can easily get a decent cheek weld without adding a cheekpiece. I have aluminum "clamping legs" on both of mine, but they are making them with steel ones now. If you want a quick on-off that leaves the rifle naked, the claw is probably where you want to be, but if you want a semi-permanent rail that you can use throw lever or regular rings on, bedding an MFI is a highly stable option.

 

shattered:

(sigh)

TRB: sigh sigh

 

No you're right, I should not speak badly of a company just because of one or two of their products, but I'd really like an illuminator for my Z-24.

So the MFi mount is now steel, or steel legs? It sure looks like a great mount, until you research people personal experience. The Swiss B&T seems like the fail safe answer.

went with this. will see how it is. figured $40 before $150 works for me.

 

Botach & Area51 have the same for $20 http://www.botachtactical.com/mosy.html

I'll prolly give it a try since a couple of people here have said that it works fine.

 

Let us know how you like it. I'm probably gonna get one like that and modify it to work with the Port Buffer I already have installed.

 

For what it's worth, I just zeroed my PTR 91 with the UTG mount.
It did just fine, with no evidence of walking and it held zero.
Since I only had time for a few rounds, I need to get back out
to the range to observe whether or not it holds after 100+ rounds.

 

Right on. Let us know how she does after some more shooting, thx

 

I have an aluminum-clawed MFI, it kept losing zero. i was ready to ditch the thing and instead decided to call the manufacturer. i spent about 30-40 minutes on the phone with Mike (?). he explained part of the problem was that the claw mount on the left side of my PTR wasn't milled properly; it was rounded on the bottom instead of square as it should be, and was on the right side.

i took the PTR to my 'smith, who put it on a drill press and used a bit to remove the right amount of material to allow the claw to grab on the left side.

it holds zero quite well, now, even taking my LaRue quick-release and EoTech on/off each time i clean it. the next time i go out, the first shot is dead on.

so good on laRue and MFI, imo their stuff works as advertised.

Mine had the exact same problem on my PTR receiver. I used a drimmel with small end mill and carefully flattened mine. MFI mount now tightens up properly but I have yet to really test it. My bolt broke after 30 rounds so i am waiting for the rifle to be returned to me from warranty repairs.

 

Got the UTG in, looks fine, mounted up real fine. Don't have optics to strap on it to shoot yet so I wouldn't be able to tell you how it holds a 0.

 

Hk or ptr rec. are supposed to have right angled feet on the right side and 45* degree angle on the left,when your behind the rifle. If some gunsmith told you its supposed to be right angled on the left,then he is lying to you and does not know specs. of hk or ptr receivers. You should not have modified your rec. ; because now an hk claw mount will never fit right. I,m sorry,but your smith is WRONG. Youy have depreciated your weapon to a collector. UTG mount is garbage,B&T is millitary and used all over the world in BATTLE. Your receiver was exactly as it was meant to be,sorry to break it to you.

 

This is nice to know, after the fact. Since I bought the MFI mount from HKParts. No where in the add does it say that 1/2 the mount won't work. The part that grabbed my eye was, in the add, --> 4 - Independent Draw Style Hooks for 100% Secure Attachment. That add maybe right after I modified that one side of the receiver. I guess sometimes I need to learn the hard way.

I assumed that PTR screwed the rcvr up since my bolt broke after 30 rounds. Guess that was not the case. IF tcr39 is correct and probably is, there are alot of people , like me, that need to be informed. Never heard of this until now.

AS of now I am satisifed with the weapon. MFI mount with old Leatherwood ARTII scope (scopes worth more than the rifle) shoots dead on. I have put 100 rounds of silver bear thru it. No movement from the mount. I don't plan on selling the rifle so collector value means nothing to me from that perspective. If it was a true pre 89 HK91, I probably would have known better since it came from HK and I would have questioned the one side of the rcvr. Like I said, since the bolt broke, I assumed there could be other problems. I still wish that it would shoot cheap surplus ammo but, what the heck.

What I don't understand is all the 5 star ratings on this MFI mount HKParts is selling. How did all these people get their MFI mount to work? Everybody grind away at their receivers?

Worse case is I can replace my AR15 with it and use it around the house with open sights out to 90 yards

 

I just installed the UTG P668 mount (the one that looks like the B&T mount) and it seems very solid. I don't think the new one (P669) mount will work for the .308 rifles, as you have to turn it around, and the feet are different on both sides.

 

Whatever, but there was nothing wrong with the receiver cuts on these 2 guy,s receivers,I just talked with TYLER from Scorpion arms and he is now selling the correct military battle proven scope mnts from B&T. The mfi mnts dont even stay zeroed either. I just dont think alluminium feet to a steel receiver are going to stay tight after months of shooting .308,eventually it wiil strip out. B&T for me guy,s, but you may not shoot as much as me;so go head and buy chinese parts for your1000$ rifle. Your choice.

 

How does the B&T mount differently than the UTG?

Again I don't have optics ontop yet, but I shot about 150 rounds last thursday through the PTR with the UTG and it's on there tight as hell...

This might be of value to anyone here as well:

Just some more info on it all.

 

The MFI mounts seem to work some of the time,but the alluminium screws and feet were stripping out. Then they re-did the feet on the mount a little different so people would be more inclined to buy them . ADAM at hk parts had a cotract type deal with MFI to buy a bunch of them to sell to PTR/ hk91 owners. Now,a few years later;people are finding out they DONT last long enough to be considered military grade.TyLER at scorpion arms also told me that he was getting alot of calls with negative feedback on the MFI mounts also. He has discontinued sales of them since. The UTG low profile feet on the p669 mount are on the wrong side to be used on a G-3/91 style receiver,I have not tried the p668 model that looks like the B&T. The left side of an in spec. rec. should be slightly angled to accept a hk claw mount., so you can roll down the clamping lever. If you do your research,you,ll see that I am correct. Norway,denmark,spain,germany,france,mexico,sweden,latvia and many more countries all use both the LONG and SHORT B&T swiss made mounts. The B&T mounts are battle proven,UTG and Mfi are not,maybe for airsoft or MP5,9mm caliber rifles,but not .308 caliber rifles. AS long as your happy with it,then enjoy. But,remember UTG/MFI are not MIL.SPEC quality. Sorry you guys ground on your weapons,NEVER alter the rifle. PTR is now selling B&T military grade mount. Have fun and enjoy your rifles. Remember, steel feet to steel receiver is going to bond if tightened down correctly and should never move. These Chinese made aluminium mounts are not going to hold up if you shoot alot and hunt with these weapons.

I do have the steel feet on my MFI mount and it still would not grab properly on that side of the receiver. No way. It had to be lightly slotted at the base of the pad for the mount to work. I did not cut the complete pads off the side of the receiver. Matter of fact, you can't really tell what I did. Very little metal was removed. 90% of that angled pad is still there. If what you say is true then the factory mount will still work on mine. My original intention was to never scope the rifle. I don't like the claw mount at all and I have a few scopes I can use. I like the way the MFI low mount works and looks. As far as mods to the receiver, I will do what I need to do to make something work to suite my needs. I have collectable's that I won't make mods on but the PTR is not part of that collection and never will be. If it said HK on the receiver then, that would be different.
