Wildgoose:
Hey AR builders. I am thinking of doing an AR M4 in the old stand by Russian 30 caliber. Being an AK fan I already have plenty of ammo and reloading components for this caliber. Am I correct that a typical M4 parts collection with the exception of 7.62x39 specific barrel, bolt and carrier assembly and mags would do the job? Or am I unaware of some other items that would be needed?
Thanks
Goose

I believe that is correct

I found that I was not getting reliable ignition in common 7.62x39 ammo with a standard AR hammer spring. I swapped in a heavier hammer spring and that seemed to do the trick. Here is a review I wrote up about my rifle: http://silencernews.com/review-mgi-hydra/

Mr. Clark is correct. The stupid hard primers of surplus ammo needs a little extra "push" to pop. It may not hurt to add an adjustable ya block to the build as well, due to some of the heavy powdered loads. This should help wih over gassing.

Just saying...   ;)   http://www.cmmginc.com/category_s/1998.htm

AK47 mags are 10 times better than any AR-Frankenmag produced.
