First i got to thinking that my "free length" measurement probably isn't a super accurate measurement. Is it normal not to be able to store 5 rounds in the magazine in stock/factory condition or it that a problem i need to be addressing first? Since a new "better quality" springs are not that expensive i will probably just get one and see if it corrects the problem. Mike G. if you would let me know if the Carriercomp spring fixes your problem.

Sorry, should have mentioned that my M4 in stock/factory condition would only hold four 2 3/4 inch shells in the tube. I almost got the fifth shell in but it needed to go like 1/4" to 3/8" further (it appeared) to be secured in the tube. The spring "free length" of the stock Benelli spring with the stock five shell magazine was 12 inches (12 1/8 to be exact). With the Nordic +2 extension on the M4, the Nordic supplied spring "free length" was only six inches inorder to hold 7 shells in the tube. That was starting with the recommended 16 inch free length and modifying/cutting the spring until the 7 shell capacity could be met (i only removed no more than an inch in length at a time) when i used the stock/factory Benelli spring with the +2 extension i could only get 6 shells in the magazine. proboly should have included this info in first post. thanks of the reply.

Hello, i just recently registered/joined but I have been reading posts on here for about a month now. I have tried (to the best of my ability) to search for a post that would answer my question(s) with negative results. I purchased a "Nordic Components" brand +2 Magazine extension for my M4 and completed the install I think/hope correctly. My main question is: has anyone had any experience with customizing the spring length for this item. After the install the spring "looked" (to me at least) kinda short compared to the OEM spring ("free length" is what i was mainly going by). Also i cant find any info on the "Quality" of the spring included with the kit? Just want to know if the spring i have is ok or if i need/should buy a better quality one (meaning spring and/or magazine extension assembly. I Have learned a lot from you guys on here so far. Any feed back is appreciated and thank you in advance. Sorry if i did not include info that is needed to answer my question, if more info is needed just let me know and I'll post it (I'm familiar with constructive criticism so it does not bother me too much....lol).
