Questions & Answers
Is this barrel able to be used on my S&W MP 15 and what if any other changes do I need to make I.E. charging handle or bolt carrier. Expert Answer

It will fit an MP15 lower. You can use the same charging handle and BCG from your MP15. All NFA rules apply.

The Aero Precision M4E1 Enhanced 16in .300 Blackout Quantum Handguard Complete Upper Receiver model APAR640112M4 has 7 MLOK mounting surfaces around the handguard.
