Question about ACE stock on C93
Hey all...first post so be easy on me ;)
I've seen some members that have this stock on their C93 or other HK clones:
(UL-M) ACE Ultra Light Modular Fixed Stock
My question is which receiver block do I need for a C93...is it this one:
(HK91RB) Ace HK 91 Receiver Block
or this one:
(HK93/94RB) Ace HK 93/94 Receiver Block
Also, for anyone with experience with these, do they require any modification or do they fit properly out of the box? I'm not a very "handy" kinda guy, but I do have a dremel so if modifications are very minor I may still go with it.
I've sent 2 emails and made several phone calls and haven't gotten any response from the retailer. Any help would be greatly appreciated. Thanks all...

Orwell was an optimist.
Thanks for the info...definitely what I needed to know. Any idea if it's an out-of-the box parts swap or if it needs any modification?
Hello and welcome to HKPro. I hope you have a great time here and learn about the wonderful world of HK as well as the always impressive Roller-lock cult. Please take some time to introduce yourself to us...
Ok enough with that.. Receiver blocks... The 91 of course has the buffer needed for the 308 round. The 93/94 use the rubber buffer for the lower powered round. As far as I know, you can use the 91 receiver block on the 93 (I might be wrong, but seeing as I both the 91 for both a 52 and 53K that GB is building right now) I think you would be good.
The 9mm carrier might be damaged if it came in contact with buffer installed in the ACE setup. I like the flush look of the 91 block better. Maybe someone who already has them installed in their guns will either confirm or correct me. Ace doesn't have the best customer service and they ship slow, but it gets to you...
Actually the ACE 91/G3 receiver block doesn't use any push ping as it fits in the back of the metal recoil assembly that holds the stock. This allows you to mount an ACE stock on your 91. The 93/94 is a Choate style replacement rear cap that has holes drilled to mount the ace folder. If you were to get one of the steel back plats from RTG (Steel Back Plate for HK93 HK33 HK53 C93 V53 V33 V93, RTG Gun Parts) then you could use the 91 on a 93 or 94 style gun. Again I don't know about the buffer and making contact with the 9mm carrier.Originally Posted by Wolvenhaven
That's the problem I had is that I tried to contact them several times for what I assumed was a relatively simple question and they never contacted me back over the course of the last several weeks.
I have seen some pics of the C93 with the stock in question from users on this site, but the links that people posted were just the stock itself...not the receiver block (unless I missed something). I'll be the first to say that I'm relatively new to firearms in general...and have zero experience with HK/clones....but I liked the looks of the C93, I wanted a .223/5.56 rifle (without going the AR route...no offense to AR enthusiasts, I've shot several and like them enough), and for the price the rifle is selling for, even if I need to do some work to it, which I know I may have to, I could still have a really solid, interesting rifle at an acceptable price.
All that said, I do appreciate the replies and anyone who has anything to weigh-in on this particular "mod" is more than welcome. The more actual user-experience the better.
I purchased the HK93 receiver block from ace first. Put 2 rounds through it and it cracked because it was plastic. I called ACE up and told them what happened and asked if I could switch to the 91. They said yes and I had to only pay for return shipping. I used the adaptor from RTG and the HK91 block. Using it and love it. My HK may have been one of the ones you've seen on here. I also recently purchased a HK91 hand guard from them for 14.00 and cut it down to work instead of paying the 78.00 they want for the one made for the 93. So far so good. I have yet to post pics of my cut down hand guard as I haven't made it pretty yet ;)...
Good luck,
Merritt
@USMC...can you shoot me a link to the RTG adaptor you're talking about? And forgive me being dense...but I wanna make sure I get everything that I need to make this work: but to get that buttstock to work properly I would need the 91 receiver block from ACE, the Ultralight stock from ACE, and the RTG adaptor? Is that everything? And with all those parts is it an easy swap from the original buttstock that comes on the C93?
Sorry if i'm sounding redundant or anything...I just would like to make this mod as painless as possible and if you've actually done it with good results then I'll follow your lead on this one. Thanks.
The adapter is in my post...

Ohhhhhhhhhh....gotcha :P. Sorry...as I said, this is gonna be my first HK-style rifle and any mods I've made before to my AK/shotguns, etc...have been real basic and changing stocks on those was very self-explanatory. I'll make sense of all this eventually. Thanks for all the help fellas...hopefully this'll be a do-able process for me.
