MSG90 Clone which Receiver ?

[The Great 308]

I am planning a build which will have some of the features of the MSG90. My goal is to have the most accurate HK91 type rifle made that I can afford. I am not trying to build an exact clone but rather an accurate HK91 type rifle for target shooting.

My question is which receiver should I use to get the most rigid shooting platform possible. My initial plan was to use a PTR 91 stamped receiver since they are made on HK tooling to original specs. However I used to own a Cetme with a stainless steel receiver and I was very impressed with the rigidity of that receiver. I plan to have receiver rails welded in which ever receiver I decide to use.

I am interested in hearing about accuracy from anyone that has the stainless steel receiver on their rifle. I have two PTR91s so I am familiar with the PTR receiver.

Also I have heard that the collapsible HK stocks will not work on the SS receiver. Is this true? If so I assume this would also cause a problem when installing the receiver rails. Does anyone have an idea of how much fitting would be necessary to install receiver strengthening rails?

Use the thick "Dan Coonan" reciever from the FA91. Integral scope rail, and the most rigid reciever available...no "weld in" BS needed!

As long as performance is the goal...and not looks, this should be your baby, IMHO.

I dont think the aluminum receivers would be as rigid as a steel one. In fact I would guess that the ptr-91 receiver would be more rigid even without welding in rails.

Ive got a cast SS receiver on my limited edition, and I shoot right at MOA or over with surplus SA. Ive shot many sub-MOA groups, but they arent consistent enough that Id classify my gun in that category. I am sure that with the right handloads, my rifle could be a real tackdriver.

All my shooting is done with a Hendsoldt Z24 scope on a HK claw mount, so something with a finer reticle and more power than 4x would probably squeeze me sub-moa as well, but Im happy with the useability and ruggedness of what I have.

Id go with the cast SS personally for building an accuracy rifle, or the PTR receiver and weld in the rails and get the authentic look to it.

I wish someone would come up with a bolt-hold-open or a drop in forward assist, and Id be more than happy to take my cetme into any battle anywhere.

Thanks for the reply it sounds like you have had good experience with these however I have seen several others on HKpro and HKweapons that have had extremely bad experiences with that same receiver. I am not sure about how rigid the receiver would be compared with the other options but my main concern with that particular receiver is the way that the trunnion is attached to the receiver. These are only pinned since they cannot be welded. From what I have read many of these rifles have severe problems and I certainly think it would be difficult to use when trying to build a truly accurate rifle.

It sounds like you are getting very good accuracy with your SS cast receiver Cetme :thumbup:. At this point I am leaning toward the SS cast receiver with the addition of receiver rails. This would give the proper look and I would think it could only help the overall rigidity of the receiver. My main concern if I do this is that I am not sure how much fitting I would have to do to the rails to get them to fit the SS cast receiver. Does anyone have an idea of the amount of fitting that might be required? My other concern is that I am going to have this rifle built and I am not sure how many builders are willing to use a Century receiver.

if youve got good w/ the JLDs already, why change? just get one and customize it to its best and your liking. would probably be cheaper and better functioning IMO

I can't offer any advice on the receivers, but i have to say this is a project that i can't wait to see how it turns out!

I *believe* he suggested the DCI receiver because it already has the rail on top. As for the receivers themselves, the guns built on them can only run as good as the builder that made them. Same as the Century's.
However, for the application you're looking for the JLD/PTR receiver is really the only option.:wink:

Thanks for the reply I really like the JLD/PTR receivers since I have two PTRs that I am very happy with. I do want to have a rail welded on the top of the receiver for optics. However the rails I am refering to are the receiver strengthing rails that go on the sides of the receiver like on the PSG1/MSG90 and HK21 to make the receiver more rigid.

As far as the builder goes I agree with you 100% the builder is everything with these rifles. I am deffinately not capable of the build. I am planning on trying to get Mark Galla of AZ Percision Arms, or Jason at IGF to build the rifle for me.

Those receiver rails are a lot easier than a scope rail. Just fit them, clamp them in placea and weld. A scope rail needs to be flat, plumb and centered.
But if you're going to have someone else build it, then send them some rails and have them do the installation.
