A: Because we’ve seen many QD mounts come loose and go down range, we don’t use them personally and don’t recommend them to our customers.
QD models are known to negatively affect accuracy, are louder due to less baffles, can create alignment issues, may drive up costs because you’ll need a connector for each weapon, and are too hot once fired to detach quickly. According to Kevin Brittingham, the founder of AAC and head of research and development at SIG, a QD mount is just another thing to worry about and align, further reinforcing the negative repercussions of purchasing and using a QD.
While we don’t see the practical benefits of a QD, we will gladly order one for you. For additional information about QD models, we recommend this article.
