[M4 mag tubes]

I agree with the Numrich tube. Perfect match w/ fatory finish and runs like a champ. Be sure to get an extended spring for the tube or your last shell or two will hang every time.

[Sugestions on Slings]

I just installed a Specter CQB sling on my M4. Good support for a heavily loaded out M4. Quick target acquisition. Perfect fit and looks great in OD. Also got a Specter buttstock shell holder in OD as well, and they look like they were made for each other as they interconnect. I would say 10/10.

Installed Numrich full length replacement tube today and tested - ran like a champ with 3" magnum buck. Excellent finish match to original barrel too. I would highly recommend it.

Thanks for the help.

[M4 Won't Feed]

Just installed my new full length tube and tried the factory spring as advised in this forum and had exact same problem. I replaced the spring with the longer one that came with the tube and problem solved.

Thanks guys - I'll give it a try. Sure hope that Numrich tube is good. The only ones I hear comments about is DMW's product.

New to the forum and I had 2 questions:

1. I ordered the 6 shot mag tube from Numrich and I was wondering about the success or problems others have encountered with this particular tube

 

2. I understand that a heat gun is necessary to remove the factory tube. Any success stories or bad experiences with this (finish damage, etc.)? Any tips or comments would be appreciated.

 

Thanks
