Here's my "go to" rifle with my PSA pistol ...
![[Linked Image from i.ibb.co]](https://i.ibb.co/BjyZSKJ/BCM.jpg)
The rifle has a 14.5" midlength-gas barrel (with P/W muzzle device) while the pistol has a 10.5" carbine-gas barrel.
The muzzle velocity loss of the pistol and decreased reliability / increased port erosion makes the pistol a bad choice.
I shoot nose-to-charging handle so I can shoot the BCM with teh stock collapsed completely but prefer it out just one notch (adds about 1" of overall length).
