Sven of Manticore Arms has some exciting new upgrades for the CZ Scorpion Evo 3, CZ Bren, and AKs.

First off he is making a transformer rail compatible handguard for the AK.

Manticore is also making a folding buffer tube for AR stocks. The folder is designed to accommodate a side rail on an AK.

With the CZ Scorpion Evo 3, Sven has designed a sliding stock and a Transformer Rail compatible free floating handguard.

Manticore Arms also made a sliding stock for the CZ Bren and a MLOK hanguard to replace the bottom of the Bren handguard.
