PRODUCT DESCRIPTION

Built specifically for the MAC 1014, this extension follows the same proven design as our Benelli M4 version: pull the limiter, transfer the spring retaining ring, thread on the extension, and you're at 7+1 — no gunsmithing required.

We strongly recommend pairing extended capacity with the Wolff Magazine Spring, since the factory spring tends to lose power with use and can cause cycling issues at extended capacity.

FULL SPECIFICATIONS & INSTALLATION

Specs: 6.5" length (adds 4.5" to the OEM 5-round tube), 1.87 oz (53g), capacity of 7 rounds of 2¾" shells or 6 rounds of 3" shells.
Finish note: the H2O Cerakote is a close but imperfect match to the factory MAC 1014 "Marine" finish, which is glossier and lighter than Cerakote.
Installation steps: (1) clear and safe the firearm, field strip the MAC 1014; (2) using snap ring pliers, remove the spring retaining ring from the OEM limiter — caution, it's under spring tension; (3) transfer the retaining ring into the new extension; (4) insert the spring and thread on the extension; (5) reassemble.
