I just ordered a HK MR762 and want to get some RL8000 furniture for it. Is the trigger guard and safety controls the same size as the MR556? As far as the safety I'm asking just for the actual levers...not the axle. First post and new to the forum. Thanks ...any help greatly appreciated
Congrats on the acquisition. You'll love shooting it.
As to your questions, I can say that from my experience, yes on both counts.
If you are looking for a RAL8k trigger guard look at HKParts. I believe it has the same flip down front spring retaining pin system as in the current US MR series trigger guards. I bought mine from GGW but they no longer carry/make them. If you use a 416A5 trigger guard you will have to trim the front retaining pin as it is not made to be a flip down system. The retaining pin is not spring loaded and goes all the way through.
DO NOT BE FOOLED by HKParts and GGW naming. The current one GGW is selling is a black version for the MR223A3, the same as the 416A5. It is A HK product. I have these on my three MR lowers. The HKParts is A5 Style because it is rounded like the A5 trigger guard but should have the spring loaded pin in it. It is after market. Call them to ask. Also see following links.

Any plan for an optic, if so which one? Let us know how it goes.
Again, Congrats and Welcome to the site!
PS - I expect there are many more HK purchases in your future!;-)
