LCT LCK12-K16 AK-12 Style Tactical Buttstock ( PK353 )
Compatible with M4 stock tube PK-340 / PK-200
I bought this product, but it didn't fit on Hephaestus folding tube stock for LCT/GHK AK series. (of course, not series with fixed) Its inner diameter is about 28.8mm so that it cannot be suitable on option folding AR stock tube. Please make sure that your choice with this review.
