Advanced aerospace manufacturing technology and a highly skilled staff are utilized to produce the industries finest, forged Mil-Spec lowers. Our receivers are machined on a multimillion dollar, automated, cellular manufacturing system which enables us to produce a product of unequaled quality and value. 

GEN 2 Aero Receiver Improvements: 

Upper Tension Screw - Allows users to fine tune the fit of the upper and lower receiver through the use of a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.

Increased Magwell Flare - Allows for easier insertion of magazines and provides a sleeker look.

*Firearm Purchases: 

No AR lower purchases available for sale in CA, CT, MA, NJ, NY, WA.  No exceptions.  NOTE California:  When we moved from WA to MT we had to get a new FFL as well as a new CA DOJ license/number which we have yet to do, so we cannot ship any firearms into the state of California.

         NOTE:  Clock starts once we have both your firearm order AND your FFL.  Once we have both, your order will process and ship within the following week.

  Check your state and local laws for any regulations that may apply.  By purchasing a firearm from MontanaAR15.com, you agree that you are legally allowed to do so.  Per federal law, you must be 21 years or older to purchase firearm receivers/frames & 18 years or older to purchase long guns.

• It is the customer's responsibility to coordinate arrangements for the receiving FFL to send a valid, fully signed copy of their FFL to MontanaAR15.com  We do not contact dealers/FFL's.  Please include the business/trade name as it appears on the FFL license, city & state of FFL in the "COMMENTS" section of your order for our reference & faster processing.
