Center-fire Pistol Rifle Breech Flag

Seems pretty sturdy and fits everything from a Sig P238 to AR Style rifles. Per a request I tapered the bottom to keep flat edges from catching on extractors. At higher infill I let the slide slam down on a Walther P99 .40cal and it didn't damage the flag. Perhaps there are better designs than this, but this gets the job done for what I was asked to put together.
