Q: Will my AR- 15 lower work with this jig?

A: Yes it will. The 5D Jig is a universal jig meaning it will work with all AR-15 lowers, polymer and aluminum.

Q: Can the 5D Tactical Jig work with my .308 (AR-10) Lower Receiver?

A: The Router Jig is truly universal for all 308 80% Lower Receivers – AR-308, LR-308, AR-10. A lower receiver is mounted in the jig in the same manner as it will mount to an upper receiver; by the front takedown, rear takedown, and buffer support. By using these known standardized features to mount the lower, and in conjunction with our No-Touch Side Plates, we can guarantee universal fitment for any AR-308 / AR-10 lower receiver regardless of exterior dimensions or slight design variations.

Q: How does the 5/16” end mill bit fit in a compact router?
