broken bolt catch

[sako55]

Broke a bolt catch at the range today. Was shooting some lake city 193. Only one mag through with the new suppressor and the catch went flying.

Is this just a defective part or is the gun over gassed with the suppressor. I have a flat spring in but do I need a heavier buffer with the suppressor.

It is a Daniel defense 10.5 inch with a standard gas block.

Any help would be appreciated.
