Bad Attitude Department AR15 Lower Receiver - M4A1

We engrave these lowers as close as we can get to the originals.  The originals were roll marked which leaves a different appearance, but we work hard to reproduce the engravings as accurately as possible.  These lowers are machined from modern 7075-T6 forgings and will not always accurately replicate the forging style of the original. 

  • CNC Machined from a 7075-T6 forging
  • Hard coat anodized
  • M4 style fire control group pocket machined to current government prints
  • Model:  M4A1
  • Manufacturer:  Bad Attitude Department
  • Caliber: 5.56 MM

Note:  We mill the lug pockets for the upper receiver at the very bottom of the specification.  If your upper is at the top of the specification, you will have a snug fit.  If it is out of spec on the high side, you may have to stone the sides of your upper receiver lugs to fit.  This is a feature, not a bug. 

This is considered by the ATF to be a firearm and must be shipped to an FFL for transfer to you. These cannot ship directly to your residence. Please be aware that because these are not long guns, you must be 21 to take possession of them at your dealer. Returns due to failed transfers will be accepted with a 15% fee and return shipping covered by the customer. Customized lowers cannot be returned for any reason other than manufacturing defect. Any transfer fees charged by the transferring dealer are the responsibility of the purchaser.

We must have a copy of your dealer's FFL prior to shipment. Either you or your FFL may email it to sales@badattitudedept.com. We do not have a fax machine.

Clone Lower

Lower has a great fit and finish, no problems dropping in a Milspec LPK. Looks awesome as a fun alternative to a Colt lower for clone rifles.
