SBI SKS Mag Block Adaptor and 3 Tapco 5/20 Magazines 7.62x39mm modified

Selling an original SBI SKS mag block and 3 tapco magazines modified to work with it. This block allows you to use modified short magazines, 3 of which come in this package. These mags can fit in pouches better and are easier to reload with in an ak style, rather than the duckbill ones. 

Tapco magazines are the best SKS mags available, known for proper feeding. These 3 have seen about 20 rounds each with no issues. Selling as I do not use my SKS much anymore, would rather see these go to a good home. 

Link below on review and video of use. Asking 50 for the adaptor plus 50 per magazine, so 200 total. Shipping on buyer. Thanks!
