From Manticore Arm's Facebook page:

The new Transformer handguard from Manticore Arms, Inc.. Keymod or M-LOK on the same handguard. Mix and match or go with one. Freedom to choose is now yours. Really impressed with these. Super light, comfortable and well designed. Thanks to Sven and co. for solving a huge problem for AR-15 enthusiasts! Under $200, 7.4 oz. 13". 8 QD sling points. Oh, don't want the inserts? No problem, rail covers available in 2 patterns, right out of the gates.
