Hey, welcome the the Benelli M4 family. Benelli collapsible stock (skeletonized stock) counts as 2 parts. Bringing the total part count to 14 foreign made parts. Silly 922® compliance laws state a foreign made gun can only have a maximum of 10 foreign made parts. The Benelli M4 ships stock with 13 and the Benelli made collapsible stock counts as 2. So you have 14. Now if you replaced the stock with a US made stock that counts as 1 part. FFT trigger kit counts as 3 parts as each trigger component counts separately toward 922r compliance. You can add a FFT aluminum follower as well for 1 part. You can replace the forend with FFT U.S. made forend to count as 1 part. Also the extended 7 round mag tube counts as one part also. And FFT sells them as well. Hope this helps.
