Silent Steel Flash Hider A1 QDB

Silent Steel Flash Hider A1 QDB

The A1 model flash hider does not require indexing, making installation straightforward. It is recommended to apply heat-resistant lock on the barrel threads.
The Silent Steel Boltlok (QDB) Flash Hider is compatible with the Silent Steel Boltlok QDB and QD suppressors.
When using a QD suppressor, a rubber O-ring must be placed in the designated groove. Do not use the O-ring with Boltlok suppressors.
O-rings are sold separately
