J R on May 13, 2018
BEST ANSWER: Any lower regardless of the markings can be used as a pistol lower...the law states that if you buy a complete rifle you can not use that lower for a pistol. So any stripped lower or complete lower my be used as a pistol. Just don’t buy a complete rifle and slap a short barrel upper on it.

Will this work with the PSA classic Blackhawk lower build kit?
Billy H on Jun 15, 2018
BEST ANSWER: I have used several Blackhawk lower build kits on PSA stripped lowers and have been very pleased. The only improvement I would suggest is to upgrade the trigger assembly with one of PSA's enhanced units down the road, they are sweet. The trigger system that comes with the lower parts kit is also a good working unit.
