Unobtanium Posted August 12, 2008 Posted August 12, 2008 Where can I get a spirng that will work with my 7-shot tube on my M4? Noone has one that I can find and E-guns is the only one that lists it and they are out. A link to a vender would be awesome! Quote
SOCOMguy Posted August 12, 2008 Posted August 12, 2008 Your factory spring should be more than adequate. Are you getting failure to feeds? You can cheat by giving your factory spring a healthy stretch to about 8"-10" longer than stock length and then you should defiently be okay. Benelli only made one mag spring for the M4 to be used with both 5 and 7 shot tubes. Anybody selling a factory 7 shot spring is only selling you what you already have or selling you an aftermarket tube spring from a remington or something like that. Quote

I heard there was a 28.5" and a 35.0" spring from Benelli? Quote
johnnywitt Posted August 13, 2008 Posted August 13, 2008 I heard there was a 28.5" and a 35.0" spring from Benelli? I guess I'll have to get off my lazy a$$ and measure the new "longer" 35" springs against the stock 11707 springs. I just got 2 of the "longer springs" from Numrich/egunparts.com. I hope I didn't get hosed. Actually, I like to have back up springs for my mags and pretty much everthing I own. This is why I can't ever find anything. Quote

Unobtanium Posted August 13, 2008 Author Posted August 13, 2008 Well, I ended up ordering from SRM a Benelli M4 2-shot Stainless extension spring (the one that comes with their Surecycle +2 kit for the M4) and the machined aluminum follower. He told me it was 32" long, but I assume that it is also of different thickness (it is SS not CS) than the factory 35" spring and if it works in their 2-shot extension tubes, it should do fine for my full-length tube.

UNSC_WARRIOR Posted August 14, 2008 Posted August 14, 2008 SRM will give you what you need. I'm really pleased with my SRM products Quote
Super M4 Posted August 14, 2008 Posted August 14, 2008 Where can I get a spirng that will work with my 7-shot tube on my M4? Noone has one that I can find and E-guns is the only one that lists it and they are out. A link to a vender would be awesome! I bought a few of SOCOMguy's Full length tubes and always either used the factory spring or if that stopped working I replaced it with Brownells part# 301-000-491 Quote
Unobtanium Posted August 14, 2008 Author Posted August 14, 2008 SRM will give you what you need. I'm really pleased with my SRM products The jury is still out for me, will post a review when I install/get it. Quote
Duggan Posted August 16, 2008 Posted August 16, 2008 I've never used anything but the stock spring, and it has yet to give me a problem in the 2+ years it's been since I installed my full length tube. Quote
Mr. Shotgun Posted August 16, 2008 Posted August 16, 2008 I've never used anything but the stock spring, and it has yet to give me a problem in the 2+ years it's been since I installed my full length tube. Thats good news... Quote

Unobtanium Posted August 19, 2008 Author Posted August 19, 2008 My SRM spring and aluminum follower arrived. It is 33-34" long and I think it will be perfect. Everything looks great. Quote
johnnywitt Posted August 19, 2008 Posted August 19, 2008 I've been messing with other guns and working at the job thing. I still need to measure my stock 11707 mag spring against the so called long springs I got from Numrich. I have never had any issues with my stock Benelli 5 shot springs either. I'm sold on the longer spring idea though. Quote
