Mega Arms Megalithic Quad Rail Upper Now Available

The Mega Arms MTS or Megalithic Tactical System is a really cool one piece upper that replaced their popular “Monolithic” uppers that they used to make. They already make a KeyMod version and now the much anticipated and requested Quad Rail version is available for purchase and it looks awesome.

The MTS uppers look fantastic paired up to a Mega Arms billet lower but will work great with any forged or billet, mil spec dimension AR-15 lower receiver. All MTS uppers also come with a proprietary barrel nut and barrel nut wrench. If you’re looking for an ultra-rigid upper/rail setup, this is it. These are available for purchase right now on www.RainierArms.com.
