Arizona_Mike 0 Posted March 15 Share Posted March 15 Normally the Military wants Type 3 amorphous "hard anodizing" (MIL-A-8625) which is thicker and holds more dye (and tends to soak up and incorporate oil). Funny thing is Type 3 is the one that allows the darkest shades of black. It sounds like they are going with some process change that allows even harder or thicker finish but does not hold the dye as well. There are a lot of new processes using other acids than the traditional Sulfuric or Chromic acid and even some plasma deposition processes. Quote Link to post Share on other sites
electric7 14 Posted April 2 Share Posted April 2 Wanted to mention, bought a socomguy black mag tube and it looks good on the 2020 Blue M4. It blends a little better than the DG parkerized tube from carrier comp. Quote Link to post Share on other sites

If Benelli is automatically extending the improved hardened anodizing process to all civilian M4 models at no cost, then why not pronounce & tout the improved finish of the vital receiver and color variance? Stranger D. may have called it right from the jump..guys at the plant in Italy have to much olive oil on their hands at the acid tanks lol!! The USMC has not purchased a new Benelli m4 in over 9 years. 1 Quote Link to post Share on other sites
BamBam 5 Posted April 4 Share Posted April 4 Correct, sorry did not mean to suggest the USMC purchased new M4’s from Benelli. From what I was told the USMC may have requested (via RFP?) from Benelli a more resistant finish, but only for/applied to the M4 receiver itself to meet the request. Essentially, the existing anodizing process was improved upon..or “hardened”.. resulting in the rather broad-blue color variance of the receiver customers are receiving recently. The existing M4 receiver nomenclature remains unmodified across the various offered models/platforms. From a manufacturing process and to streamline production, it is certainly practical to produce all the M4 receivers consistently in the same manner & steps..therefore extending the new hardened finish across all M4 receivers. If this is the case, just don’t understand why Benelli would not pronounce the new-hardened-finish of the ever-vital receiver and with it comes the disclosure of the known color variance. A possible reason..and this is only my ignorant opinion..is disclosing the known color variance of the receiver will scare off any potential buyers who want an all black M4. 1 Quote Link to post Share on other sites

Yes that is interesting.. I see yours also has the 2020 date on it.. I see yours and the other ones all are 5+1 and PG stocks.. mine is the 7+1 model .. I 've now seen the ones on here and one other one with the 5+1 and PC stock that also has the blue hue.. I don't mind the look just wonder why some do and some don't..

FFMichael 19 Posted May 5 Share Posted May 5 The blue "fuck up" has been around for a long time. Here is one in this youtube video from 4 years ago, and I have a friend who had one like it from factory in like 2012. It's always been a thing for some to be blue, not really a quality control flaw, as it doesn't affect the quality of the gun. All that being said, I do understand that if you want a black gun, it could be upsetting to not receive one. Benelli should just start actually labelling the ones that turn out blue as such, and then sell them as that separately from the black ones. 1 Quote Link to post Share on other sites

StrangerDanger 550 Posted Friday at 11:26 PM Share Posted Friday at 11:26 PM Benelli should sell them as a thin blue line law enforcement edition. People will pay a premium! A forum member sent me a blue M4 and a black M1014. The color is drastically different between the two. They used to release a bunch of M4’s that had an OD green hue. The blue ones still look better than the purple Barney preban Bushmaster AR-15’s. 1 Quote Link to post Share on other sites
