What Buyers Ask
What jig is required to finish this lower?
This lower is designed for use with a standard, multi-use .308/AR-10 80% lower jig. It is not compatible with jigs made for AR-15 platforms. Ensure your jig is specified for DPMS-pattern large-frame receivers.
Does this work with both .308 and 6.5 Creedmoor uppers?
Yes. This DPMS-pattern lower is compatible with uppers chambered in .308 Winchester, 7.62x51mm NATO, 6.5 Creedmoor, and other cartridges that share the .308 parent case dimensions, provided you use the correct magazine.
Is the rear takedown pin hole threaded?
No. This receiver uses a standard, non-threaded rear takedown pin hole. The included threaded screws are for securing the receiver to a compatible machining jig during the finishing process.
