So, the only problems I had were with the 20rd straight mags. More issues with the suppressor & flat nose 147gr together. Used AE & Blazer brass.

Both 30rd mags, new & older gen, were flawless with & without a suppressor. No issues with either flat nose 147gr.

The Stribog suppresses well & is a very smooth shooter. Trilug is simple to use & better than direct thread when possible.

A friend has an MP5 clone & it shot even softer than my Stribog.
