I finally got my Oly .45 magazine to feed my .45 upper with the liberal use of my dremel tool.

Now I have a new problem. The bolt seems to be cycling too soon and ejecting hot gas and burning powder. I am left handed and find it difficult to shoot with burning powder being sprayed in my face. Will a heavier recoil buffer delay the blowback enough to help? Does anyone make a block that covers the rear portion of the ejection port similar to the ASA or Colt 9mm?

Why not just install the 9mm deflector parts as you have described? Should be able to get from RRA, Pete, ASA. I know the parts are listed at RRA' site.

I will probably install the deflector but I am concerned about the action cycling before the powder is consumed.

I experienced the same blowback of gasses and particles with my Olympic Arms PCR-45. I installed the 9mm gas block and it cured my problems. You can order the parts from Brownells. You will need: 1. 160-302-029 SP62854 EJECT PORT COVER ASSY 9MM $12.44 2. 160-302-030 SP62851 GAS DEFLECTOR 9MM MODEL $12.44 3. 160-302-031 SP62769 GAS DEFLECTOR SPRING 9MM MODEL $4.38 You will reuse the ejectrion port cover spring, rod and E-clip. Make sure you get the gas deflector spring or the gas deflector will flop around.

Try some different ammo also. My 9mm Oly spits a lot worse with certain ammo brands. I am left handed and wear contacts, so I certainly feel your pain! Get some shooting glasses.

I get a little spit from my .45 Oly AR upper also. I've just always attrubuted it as a fact of life with a blowback rifle. It is hardly a major distraction to me. The upper functions perfectly and is quite accurate. Hitting a man sized target out to 100 yds is quite easy. later, AJ

You might get some benifit from a heavy 9mm buffer. It might delay the extraction long enough to lower the pressure in the chamber.

I added a heavy buffer to my AR-45 and it felt better. If you use the heavey buffer make sure you use the spacer for the full length buffer tube.
