Mega Arms AR-15 forged lower receiver (multi-cal)
This forged aluminum lower receiver is compatible with all mil-spec AR platform forged upper receivers on the market. It is hard-coat anodized, with the Mega logo fully engraved on the (shooter’s) left side of the mag well. Lower receivers are sold three ways: (1) stripped as individual parts, (2) together with parts for you (or your gunsmith) to assemble or (3) as part of a complete lower that we build for you.
FFL REQUIRED: You must state which federally licensed firearms dealer will be receiving your lower receiver (whether assembled or not) in the comment box during checkout. Please have the dealer fax or email a signed copy of their FFL to Bison Armory. Our contact information is available HERE.
Lower Parts Kit Option: The LPK includes an ALG QMS trigger as standard. If you select one of the other triggers offered under “Trigger Upgrade” your LPK will be upgraded accordingly.
Buttstock Option: If you choose to purchase a buttstock with your lower, you will receive a buffer tube and components. Otherwise, the buffer tube and components are not included in the purchase of a lower receiver.
Upper Receiver Option: If you choose to purchase a matching upper receiver with your lower, the upper receiver will come with the ejection port door and forward assist installed, except in the case of a Mega side-charge upper. If you are planning to buy an upper assembly along with your lower, and do not want an extra upper receiver, do not select the upper receiver option on this page.
Assembly Option: If you do not check “Assemble Lower”, you will receive all your parts unassembled. The assembly of the lower kit should be performed or inspected by a qualified armorer or gunsmith prior to use. Proper assembly of the lower kit is the responsibility of the end user of this product.

Lead Time & Billing: Currently, Lower Assemblies are shipping 4-8 weeks from the date of purchase. Stripped Lowers, with or without parts, ship within 2-3 weeks of receiving FFL information. Your credit card is charged at the time you place your order, not when your order ships. Please consider these factors before you place your order.
