BudsGunShop.com - Will this fit?

Haile, it won't fit, but even if it would, it would change the classification from a pistol to a short barreled rifle. That would require registration with the ATF and a $200 tax stamp. You can add a pistol brace without changing the classification. >>> budsgunshop.com/product_info.php/products_id/718006143/sbt+sob-47+sob-47+pistol+stabilizing+brace

Hale, unfortunately no. This is a Shoulder Stock and would also change the classification of your Hellpup to an SBR (Short Barreled Rifle) requiring NFA Registration and a $200 Tax Stamp. Cheers and stay safe!

No this is for Yugo style AKs.
