Thordsen Customs is proud to announce the release of the FRS-15 GEN III Featureless Rifle Stock. This new design builds on what was learned from previous versions and through customer feedback. It offers distinct form and function and provides new options for shooters while its predecessor, the current FRS-15 Gen II, remains a relevant and economical option for featureless conversion.
Legislation towards the AR-15 and other weapon platforms, in states like California and New York, have made “going featureless” a viable alternative to forced registration. Just like with earlier models, the FRS-15 GEN III is designed to help law abiding citizens keep their firearms in compliance with current and upcoming laws. Additionally, the more traditional rifle stock look and feel of the FRS-15 GEN III appeals to gun owners nationwide and not just in restrictive states.
