NOTE: This service could take up to 3 months. This service requires us to repurpose and retool a CNC machine to perform the modification. This is a half day operation just to set up the equipment. Therefore, in order to keep the cost of this service reasonable, we will need to hold orders until we have at a minimum three units waiting for conversion. The maximum time we will hold a unit is three months, regardless of how many are waiting for modification.
SAM7K Right Side-Folding Stock Conversion
Add a right side-folding stock to your SAM7K pistol! This converts your pistol to an SBR which requires NFA registration. Customer can file and receive ATF Form 1, and send us a copy before we are able to perform the conversion. Or Arsenal can register the SBR after the conversion is complete and transfer the firearm to the customer’s FFL for processing. The cost for this service is $1,199.00 and may take up to 3 months, as noted above.
