    Bought this as part of a larger build project. taurusx22frt.com had the best price by a decent margin and shipping was fast. The MAS Defense M3/M4 Drill Bits for Polymer80 Frames - Precision Tooling for P80 Builds itself is well-made — Quality control is on point. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
