Hi- I have a stainless target Mk iv, more than 1 blued “uppers” and a VQ mamba upper. I also have VQ and matrix precision bolts, plus Ruger bolts (Both stock and most with VQ extractors).
in my experience (several thousand round) blued Ruger uppers jam the same as my stainless upper- with same bolts, same extractor, same mags, same ammo. The VQ jams less(as expected).
If you continue to have problems- i personally would recommend trying different ammo, checking your mags, and installing a VQ extractor first, and see if that helps. If not, then consider buying a performance bolt.
Hope this helps and works for you
