Questions & Answers

Description starts BA-15FC 16 inch. Then in detailed description 18 inch. Which is it?I don't want to have to return it . Looking for 16 INCH

Hey Reggie, the only 18" barrels are the 416R stainless steel barrels on the 22ARC and 6MMARC. All other barrels are 16" lg. The only other barrel lengths can be found on the Bilson Arms pistols at 12.5" and 14.5".
