Got my RRA and the only thing wrong is the safety is on the port side. I bought a ambi unit from Brownells. To put it in do I have to completely disassemble the lower or is there an easy way to swap them out? Thanks for helping a newbie learn....

Sorry, I thought I had something to add, but I don't

Remove the upper from the lower.

Pull the hammer back to the cocked position. Flip the lower upside down and remove the handgrip. be careful when you pull the grip upward. There is a spring and the detent for the safety selector hidden under there. The spring will be visible. Remove it. turn the lower rightside up over a towel or something that will catch small parts and wiggle the safety on and off. The detent will fall out.

Slide the selector switch (safety) out and slide in the new part. Finish the assembly of the new selector. Turn the lower upside down. Find the detent and insert it into the hole it fell out of, pointy end toward the selector switch. Re-install the spring. Re-install the hand grip, try not to smash the spring sideways when compressing it with the grip.

Function test the new selector switch.

Thank you AR-10. When I saw "RRA" I wasn't think Rock River Arms. :o Couldn't figure out what type of gun until you posted. :p

Happy to help.

One word of caution. The last ambi-safety I bought came from a gunshow dealer who bought it from Brownell's who bought it from DPMS.

DPMS sells a very nice ambi-safety, superior to the one I bought from Bushmaster. The one I got from the gunshow is the third DPMS unit I have purchased.

Unfortunately, it did not fit! For some reason it is slightly out of spec and would not pass through the hole in the reciever. I tried for ten minutes to push it through, the result of my efforts being a pre-ban reciever that lost a bit of the finish around the hole I was pushing against. I got so frustrated I took the selector off one of my other rifles just to prove that the new part I was cussing was defective.

The first two DPMS ambi-selectors have given me good service. The last one was a clunker. If it doesn't slide right in, don't spend a lot of time forcing it. Don't bother trying to round off the leading edge thinking a burr is making the part dificult. Just send it back for a replacement.

I expect you will not have such a problem.

Why not leave it stock and use your left thumb for the selector? Just put your thumb on the outside (left) rather than as normal. Otherwise, have fun.

I use that method a lot for flipping the safety on.

Flipping it off that way is a pain if you are prone or the rifle is benched and you have the sights lined up on a target. It is much easier to flip the safety off if you do not have to move your trigger hand or your head. That is where the ambi-safety shines for a lefty shooting an AR-15 ( or a 10).

AR-10,

In what way is the DPMS version superior? I bought a ambi-selector from GunSmoke Enterprises, who I think bought it from Bushmaster. There is a roll pin that you tap in to hold the plate on the right side and a set screw on the outside to keep it in place. It was a hassle to install, but seems to work OK.

I've also found the saftey on the AR to be anti-lefty. For close in, starting with the saftey on, the selector has to be engaged with the thumb, for the fastest times.

I've got an Olympic Arms on mine that can be installed on either side depending upon which side you want to orient it on. It is not an Ambi. and I prefer it that way. Cost was about $10 if memory serves me. I like it much better then the right-handed safety.







Stay Safe, Pat S

Thanks for your help AR10. I'll try it tonight.... Bob

The roll pin is the only major difference between the two brands. The Bushmaster unit is nicely machined and works great.

It is pretty easy to remove the DPMS part, requires an allen wrench. Pulling the roll pin out of the Bushmaster model looks like it will be work. I've never tried to disassemble it because of that.

The Oly Arms reversable type sounds handy, but I like to have the safety on both sides so it does not confuse others who shoot my rifle. It would be nice not to have the extra lever pressing into the web of my hand when I am shooting though.

Thanks again for your advice AR-10, it worked perfectly. The unit from Brownells did have the hex screw on the right side. Also it was a very tight fit. I put it in the vice and did a "shoe shine stroke" on the new unit with some fine emery cloth then hit the exposed metal with some cold blue. It now works like a charm.
