Started life as a Sig Rattler LT and a forward assist was added along with Sig's LE/Defense suppressor handguard. 

Additionally, parts like safety lever, mag release and forward assist button were added from Forward Controls Design. 

Will include the original Rattler LT handguard and either Parker Mountain Machine Minimalist stock or Parker Mountain Machine's Kate Moss stock. 

$2700 for Gun with both handguards. 

$4200 if you wish to add the Surefire XVL2, Eotech EXPS3 or Aimpoint CompM5 as well as the Surefire mini-scout with Malkoff Devices head and Unity LightWing button/Switch. 

Add $500 for the Q Trash Panda. 

Since this gun started it's life as a pistol, it can be sold as a pistol via Title-1 Status. This means I submit a notification to the ATF NFA division to remove it from the registry. You can take the gun immediately after that is submitted, but will not be able to turn it back into an SBR until verification is returned to me from the ATF saying it has been removed from the NFA registry. 

Stamps are free anyway. You'd either wait to SBR and have the gun in your possession, or wait to pick up the gun as an SBR. Your choice.
