Has anyone ever tried an Olympic Arms OA93 or 98? Do they use the same gas system as the Ar15. How do they compare to the AR15?
Thank Bruce

Yes, we sell them.

They use the same gas system, but use a pig-tail gas tube to increase reliability.

They work very well in semi-auto and full-auto!

I own one and they are reliable after first 100rds. Of course, quality ammo is always better but will shoot anything.

i've always wondered, how does the buffer system work?

Hi Robert, Glad to hear it works well.

Are you saying first 100 rounds each time you shoot, or the first 100 rounds for the upper?

Just curious!  :-)

I have another question, is the bolt carrier the same? Would I be able to use a RDIAS in it?

If you have a RR M-16 ZM weapons makes a sear you could add that would work.

I think the recoil spring is a 1911 recoil spring but I'm not sure.

The semi and full auto bolt carrier are different...

OK, you got me curious...  Care to expand on this more?  :-)

The Full auto ZM uses a dog leg sear catch that attaches to the existing auto sear and basically extends it forward.  The shorter ZM bolt has a nub on it that when the bolt is all the way forward it trips the new sear that is farther forward and the dog leg operates the original sear which will release the hammer.

This is an option for a Registered Reciever only, I'm pretty sure it wouldn't work with a RDIAS. It also requires one to drill a hole in your M16 lower (yikes, I don't know how many people would be willing to drill into there M16 lowers).

In order for the ZM sear to work with the OA93 you would have to modify the bolt to have the nub that sticks down that trips the sear. So it would probably be a bit of a hassle.

Or maybe you could just use a ZM weapons bolt and sear?  

I wonder what those would cost? (or if they'ld even sell it seperately from a kit.)

Came tight from factory. After first 100rds of owning the gun, bolt worked flawlwss, closed always and worked %100.

Great!  I thought that is what you meant! ;-)  Glad to hear it works well for you!
