S&J Hardware Benelli M4 Magazine Extension, Black

Canadian law mandates that semi-automatic shotgun capacity is restricted to 5 rounds of the largest capable shotshell for that shotgun. The Beretta 1301 is designed for 2 3/4" inch shells and 3" shells. So, the legal limit is 5 rounds of 3" shells for the Benelli M4. Our Canadian Legal magazine extension tube will allow you to load 6 rounds of 2 3/4" shells into your magazine tube, as per Canadian law.

• CNC machined from 4140 steel.
• Overall length - 6.5 inches
• Once installed, these tubes will fit flush with the end of an 18.5″ barreled Benelli M4 12 gauge shotgun.

Finished product is Cerakoted

• Graphite Black

Unlike most of our other magazine tube extensions, our Benelli M4 magazine extensions do not come with a spring or no-jam follower. The OEM spring that comes with the M4 will function just fine with our magazine extension. If you do happen to require a new spring or follower, one can be purchased on our website.

Made in Canada.

Compatibility

Compatible with Benelli M4.
Can't confirm fitment on Turkish clones. Unfortunately, there are a handful of different factories producing parts in Turkey, and some of them use different thread patterns. Some companies will purchase parts from different factories for different batches of the same firearm, based on price fluctuation and availability. It is impossible to say with 100% certainty which firearms will be compatible. Some companies are more consistent than others with their sourcing of parts, but we still can't guarantee fitment 100%. The onus is on the buyer to determine the thread pattern. If you are local, you are more than welcome to bring your firearm into the store, and we can test to see if an extension tube will fit before you make the purchase.
