- For Specna Arms CORE™ and FLEX™ M4/AR-15 AEGs
If your Specna Arms CORE™ or FLEX™ needs a style-up, check this out! The SAAS Polymer Receiver for M4/AR-15 CORE™/FLEX™ AEGs from Specna Arms is a great way to give your CORE™/FLEX™ M4 an ultra-modern look, being patterned after real steel "billet" receivers with unique Specna twists. This receiver is made from polymer with steel and alloy trim parts.
Unlike other receivers on the market, the SAAS receiver includes all of the external trim parts needed to complete the build, from ambidextrous fire selectors and an ambi mag catch to an extended charging handle, bolt catch, mock bolt, forward assist button and trigger guard. Specna even includes an ESA steel quick-change spring guide!
Compatibility-wise, this receiver is designed specifically for the Specna Arms CORE™ and FLEX™ M4/AR-15 series but should also work with other M4 AEGs, potentially requiring modification. If you want to give your CORE™/FLEX™ AEG an even more premium look, the SAAS Alloy Receiver for M4/AR-15 PRIME™ AEGs from Specna Arms is the way to go!
