For proper installation the alignment collar requires a two inch space behind the muzzle threads. A step of .700 diameter and length of .640 is needed when using the two piece mount. A dimensional drawing of these requirements is included along with recommendations of companies that provide this service. Installed the MRS (Mini Reflex Suppressor) adds less than 3" to the overall length.
