Detail

Fitting it and the fine print

Will this fit my AICS pattern bottom metal?

Only if it is cut for CIP spec or 3.850 inch magazines. Standard AICS pattern bottom metals use the shorter 3.715 inch magazine well and cannot accommodate this CIP length magazine.

What is the difference between CIP 3.850 and standard 3.715 inch magazines?

Our record says the standard 3.715 inch MDT long action magazine takes cartridges up to 3.615 inches overall. This is the longer 3.850 inch CIP version for chassis and bottom metal cut for the CIP magazine well.
