So I built a 9mm AR pistol with a PSA upper and a Spikes lower with mag block for Colt mags.
I am reloading my own 9mm with TightGroup and the reloads have always been a bit dirty but have always been accurate for me so I haven't wanted to change.
Now running them through the AR they are coming out VERY dirty and I have had some split jackets.
I am thinking I need a heavier buffer/spring and/or a spacer in the back of the tube to slow the bolt down....does this make sense?
If so what are you guys using on yours to help slow things down??
Also I believe I currently have a 5oz buffer?
