Ya as mentioned above it should install no issue, a thread is a thread. As long as the tube is machined correctly with proper thread tolerances the cap will work.

I toyed with the idea of making a different design altogether, more straight out without the 3 large circles machined into it. But in the end, I find benellis cap design quite beautiful so decided to keep the classic look of the cap even though I probably could have achieved 1/4” to 1/2” more spring space.

I would run the gun with OEM mag spring and 7 round tube, and put the rest back to stock and see how it runs. Imo, the OEM mag spring is just fine for 5 round tube and 7 round, Benelli uses the same spring in both mag tube lengths. If it fires fine in this configuration then you know it is something else.

Is that larger charge handle made of out metal or polymer like the 1301?

I think this test is a joke compared to the 25k round test the USMC did. Who needs to test the M4 for 500 rounds? What’s the point? When I test products I’ll easily go through 500 rounds in one session, and this is after not cleaning the gun for the past thousand rounds. Sorry if I sound harsh but he’s trying to get click bait testing the most battle proven shotgun ever made. Meh.

There will be some videos this summer from YouTubers. I’ll post links when they are up.

this particular receiver is an older gun from around 2013 or so I believe (still has the aluminum trigger assembly), I have a couple other M4s and to be honest I just shoot em and I haven't even looked at the colour of the receiver hue 🤷‍♂️

There will always be movement with all the components up there (barrel, mag tube etc). It is very stiff, I’ve been testing with a 2 cell weapon light, and have had no issues with the front touching the barrel. it is 1/8” thick…

Yes. However, their bracket clamp method is “proprietary” so I didn’t pursue that path. additionally, the rear barrel hanger is known to be off Center at times. On all my guns none of them have a straight rear barrel hanger, and all of them are different. I’ve come up with a solution to offset the clamp to center it for the user, which would not be possible using the same clamp design as the IWC. There are plenty of mlok slots to mount a QD on the heat shield, the bracket doesn’t need one. And the user can put their QD wherever they want. Some will want far forward, some will prefer near the rear barrel hanger, so I decided to let the user do what they want.

This is the way.

Normal

I did forget to mention, that if you use my cap on a tube without a retaining spring, you will get an extra 0.15” of spring space Vs the OEM. I know 7 shell in the tube is tight with certain loads. The 0.15” extra might be able to give that little bit more that is needed. I tried to hollow out the cap as much as I could to give more room for the spring.

I also use that same one but a different brand in Canada. (I’m sure from the same factory in China). it is a good quality torque screw driver with fine tuning of the torque values. It also has a low +-2% range which is lower than the majority of torque screw drivers in this price range.

I also use the lower hole on my M4 (obviously since I use my own product) and I don’t find and issues at all..

All good suggestions, I’ll see what I can do

Gen 2 is not accurate, as that would imply “gen 1” is discontinued, which will never happen..

What kind of design are you wanting? I was going to get into the safety next at some point.

Ya I gotta be honest I’m probably not doing this. Thanks for all the input guys.

Muzzle end is floating yes, with SBS would get the slots after the bracket but the front 3 on the full length would be gone. Would look pretty good I think.

Pumps we can have short barrels as long as it is from factory (not restricted at all). Semi auto Center fire needs to have a minimum 18.0” barrel.

Thanks! I’ve been asked about the SBS. I haven’t looked at the mlok spacing, and I don’t have a 14” barrel to test out as that is illegal in Canada (14” barrel semi auto). chances are slim… however, it might be possible to hack off some front slots with a good aluminum cut off blade, and debur and then do a touch up annodizing kit on it. m4 barrel is 18.5 inch, so I guess the SBS would need a heat shield that is 4.5” less. Just measured and you’d lose the front 3 slots. maybe I’ll try to make a few during the production run and I’ll send one off to someone to test…

Thanks! This one is going to be a big venture for me, so far interest has been good. the weight is 188g (6.6oz) with all hardware included. I have considered doing QD cups on the bracket, but ideally QD mounts should be mounted higher up on a 2 point tactical sling setup, when the gun hangs in front of you it will sit nicely when tight, if the QD mount is as least mid way between the barrel and the mag tube from a weight balance perspective. So any of the mlok slots are a good choice to attach an mlok QD accessory.

No compatibility with any other mount than the ones I am offering. The boss and boss hole add strength near the reciever and allow a tool less takedown. Other wise it would not be possible, and there would not be any contact at the rearward part of the shield to keep it secure. it is secured by a clamp on the mid barrel guide ring. The shield itself is 1/8” thick to ensure proper stiffness at the front. In my testing of many hundreds of slugs and buck, with a 2 cell weapon light near the muzzle, it has held up very well, with no signs of movement once it has been secured in place.

Wish I could lower it, but it’s an expensive piece to machine, it isn’t just an extrusion like other handguards, it’s machined from billet inside and out. It’s 16” long, and has some precision machining on it which is costly. as for the optic cost, new M4 owners won’t feel the cost as much as older M4 owners as they haven’t upgraded anything yet. Picatinny is the cheapest way to upgrade. I might adjust the pricing before offering it for sale, trying to make it as cheap as I can.

Hey all, Excited to announce this project, which I've been developing since Fall of 2022. Specifically designed to be fully compatible with the OEM Polymer 2pc Benelli M4 Handguard (Benelli 70117, and Benelli 70116). This brand new concept revolutionizes the way the Benelli M4/M1014 handles. It gives the user multiple options for accessory attachments, protecting hands from barrel heat, all while retaining the superior and unmatched ergonomics of the original Polymer 2pc Benelli M4 Handguard. Machined from billet 6061-T6 and mil spec hard coat annodized. Once installed, this Heat Shield offers fast, and tool-less takedown of the Benelli M4/M1014. Fully compliant with ARDEC Solicitation DAAE-30-98R-0401. It is not any slower to take down the weapon than if you didn't have the heat shield on at all. The design requires an Rx Arms Optic Mount to function (as the receiver optic mount has a boss hole which accepts the heatshield). Initially will be offering a mil spec picatinny rail, and RMR rail. To follow will be the aimpoint T2, and P2 rails in early 2024 it is looking like. All optics will co witness from close range to long range. If you are interested, you can sign up on the waitlist at rxarms.com. It is looking like Q4 2023 for availability. If you have any questions I'd be happy to answer anything I can.
