I build a CMMG Colt pattern, but i really wish I did a QC10 glock style build.
So the lack of a "bolt hold open" feature on a Glock lower doesn't sway you away from that style?

I found an article that talks about the difference between the Glock and Colt lowers. I'm not sure how accurate it is. The one thing that I find surprising is the article says that the bolt hold open does not work with the Glock lowers and something about the Glock lower parts could be unique/proprietary. Does anyone know if these are true?

◾Bolt hold-open functionality on empty magazines does not exist with Glock compatible lowers.
◾Requires unique/proprietary parts which increases costs associated with the initial build and any ongoing maintenance/repairs.
The bolt hold open after last round requires a different type of Magwell block for Colt mags as well or an add-on pice for the drop in that does not make it a simple drop in anymore. Hahn has one like that also but, it is not an easy swap out when wanting to switch back to 5.56.

My dedicated Colt has a bolt hold open.
QC10/DDLES Glock lowers have a LRBHO. Where people get a bit confused is that Lone Wolf and some PSA lowers don't have it, because the system is a bit complex and thus costs money to implement.So the lack of a "bolt hold open" feature on a Glock lower doesn't sway you away from that style?
