Normal Suit talks about the Marksman K1A GBB Rifle which is based on the ROK service rifle and made in Taiwan... "An unprecedented event occurred in the airsoft gun market where a Korean gun was made and sold in Taiwan, and it was also made with a gas gun. This product was produced by a new company called marksman and sold for a frightening launch price of $1,900. The product is already sold out and it is unclear whether it will be sold again, so it is a limited edition.

The MOA Exhibition 2023 features the Marksman GBB PCC, a gas blowback airsoft gun with the V-system, at the Action! Airsoft booth. This gun has an AR9 /9mm PCC style, a steel flash hider (14mm CCW), an integrated CNC aluminum outer barrel, and a CNC aluminum 7.5" M-LOK handguard. It also has a steel magazine release, a steel bolt lock lever, a steel hammer and sear, and a CNC aluminum bolt carrier. The magazine well system is adjustable, and the buffer tube is one-piece.
