Will I need a different buffer or can I just slap the upper on my RRA lower (for the Gov't model 5.56) , put in the mag block, put in a modified UZI mag that RRA sells and go to it?

Thank you for any help.

there are faq threads tacked at the top that should have the info.

would need the bolt group, hammer and a hevier buffer would be wise.

Actually, I tried the FAQ and it looks like just another rambling thread with some information here and there not organized in a typical FAQ point form question/answer format. It didn't answer my question in the time I gave it (although maybe my question isn't "frequent").

Thanks why I'm thankful ARFCOM is a discussion forum.

Thanks for the info.


ETA: Oh look! I found something unformatted in a run-on string that is a response and I can't really tell if it's part of the "official" FAQs or just some guy who doesn't know:

I don't know...I am still glad I asked.

think the board codes were messed up some how. causing the words "quote" to show up instead of actual

quotes




although jumbled they are still there

Seems like it would be easier to just answer the question than tell you where to find it.

I have used the standard 5.56 buffer with no problems. When I did finally decide to buy the 9mm buffer, my rifle wouldn't function anymore. Been using the 5.56 buffer for almost 2 years with no problem at all.

LOL THe 9mm buffer jacked it up but it worked with the 5.56 buffer...OK, that's weird but it'd make it easier for me.

Thanks for the info. I'm interested in a different upper or two and I though a 9mm would be cool.

Cheers,

The buffer isn't going to be the issue with your setup. If you are swapping calibers you may have some hammer issues. Both of my 9mm ARs are dedicated so I don't know the specifics.

Rock River lists all the required parts on their web site. You just need to do a little looking.

Thank you for any help.



You do not say which stock you have..........

If std rifle stock, leave it alone, though I weighted mine to 7oz because I run a suppressor quite often with 9mm.



If CAR stock, you "MIGHT" consider the "9MM" CAR style buffer just for the weight, it is a few points heavier than the std rifle buffer --> 5.1 vs 5.5oz avg

DO NOT put a CAR buffer in a rifle tube, no matter what RRA says, accident waiting to happen.

They get scrambled every time the board format changes... all that has to be done is the poster has to go back and hit edit, and submit, though he/she be wise to simply space it back out before submit again... look at my posts, most should be back in line correctly.

The only hammer needed is the basic M16 hammer missing the "auto lug" for semi-auto use, DPMS and a few other vendors sell this hammer, then swap tops to your heart' content.... you dont see M16 owners swapping hammer now do you?

Thanks for the 411, I knew this part of ARFCOM would be a wealth of information.
Good thing we have a specialty forum dedicated to this subject.

Thanks.

I have the 6 position "Tactical CAR stock" with my carbine so based on what you're saying it sounds like I might consider the 9mm buffer.

As for the hammer, I honestly don't know. I will have a look at it and compare it to the pic you posted.

Thanks again.
