UBAR-LFS: Laffs Dynamics

QoL improved variant of the original UBAR AR-15 3DP lower receiver. 

Has H&K style fire selector markings, an opened up trigger guard, and lightening cuts in the magwell for less material usage during printing. 

A small amount of material is removed from the rear of the receiver to allow for full tang AR grips to be utilized. 

In the original UBAR design, the inside top section of the trigger guard (Where the trigger meets the receiver.) was wide open; this has been closed off to keep debris from entering the fire control group.
