Looking forward to what you come up with.

Thanks RxArms, yea every shop I spoke with talked about media blasting the entire receiver as the only option, and applying Cerakote to the inside and outside of the receiver - So I opted out of that. I have put my trust in Wright Armory and their new NT7+ formulation. I will share with you once I get it back. Thanks again, ZL.

Yea I thought long and hard about this. I did not opt for Cerakote due to the internals and the operation of the receiver. But, I am considering a true composite which is evenly distributed and locked into the aluminum substrate, a nickel-phosphorus matrix coating adding approximately .0002″ in internal tolerance, and has a super low coefficient of friction. It's called NT7+ and replaces NP3. Perhaps StrangerDanger or RX arms can also comment on adding internal tolerance to the Benelli. I don't have enough experience to know. The guys at Wright Armory, who formulated the new NT7 say that there will be no issues.

from what I have read in this forum, which is substantial, you don't need a new spring. Others have tried and the original spring works just fine. But I would be surprised to know that your new tube didn't come with a new spring. I think that CARRIERCOMP makes the best tubes and they come with a new wolf spring. https://www.carriercomp.com/

So I completely effed the finish of the receiver. I got impatient and over aggressive with the MAPP torch. Does anyone now if I can get my new finish back? See pics.

Thanks RX Arms. Good advice. If I were to do it again, I would put a 1" hole in a piece of welders cloth shield and slide in all the way back to the receiver, and then just torch the tube. This would have protected the Cerakote finish. Once the tube it hot enough, it will come right off with very little turning pressure. It came right off like butter but I slightly discolored the receiver Cerakote finish.

So yea I just torched it for about 3 minutes and it came right off. And I did simply unscrew my stock, I didn't know they were so easy to take off. Looks like my fixed stock (CAL edition) came with the adjustable/collapsible type extension tube... Thank you for the help.

So I been going at this sucker for an hour with a heat gun at 300 degrees and I can't get this tube off. This is a new M4 with red lock tight (I can see it). I have the receiver (carefully) in a vice. I tried using some heavy duty nylon strapping and a pipe wrench, but no way. Soaking it overnight with some PB Blaster. Question: Is is ok for me to leave the grip/stock on it when I hit it with my torch? It looks like the receiver retains a LOT of heat whereas the tube doesn't. I really don't want to take the stock off. And can someone comment on the best place to focus the heat? And what about a strap wrench? And should I not worry about destroying my stock tube? I already marred it up a little. Any help is appreciated.
