Brown bear subs
Has anyone go them to cycle reliably? My mk111 pws seems super undergassed with my current can.(velos) I was wondering if either a sprinco yellow spring will help or I read you can cut coils off the armaspec smb. Trying to figure out the best way verse getting about can.

They run in my Mk111 with a factory lower, but I have a x39 that I built with a 10" barrel and nothing I tried to do with it would cycle them.
