Would you be interested in trading barrels?

ya the only difference is ours has a 1913 mil spec design (full picatinny slots, no cutout down the middle), and it has a boss hole to accept the heat shield, and I feel the front is a lot more smoothed out compared to OEM, creating less snag potential. It is the same height as the OEM, so in theory, any optics moved from OEM over to the Rx Arms picatinny should be pretty close to zero requiring a small adjustment probably.

It should be mentioned, and I will include this on the product page.. the heat shield does have minor amounts of play where the boss meets the optic rail, I am talking thousands of an inch, which are necessary for the tolerances of machining. After 2000-3000 shell on my receiver, it does show a small wear mark due to the heat shield rubbing against the receiver. This mark can probably be covered up using some Birchwood Casey aluminum black if one decides to get rid of the heat shield down the line, but I haven't tried to blacken the shiny spot. There can be ways to eliminate the play, such as a ranger band going around the heat shield and the mid barrel guide ring for example, or a ranger band around the heat shield and the forearm, or anything that will snug the heat shield down toward the hand guard. For me, and I realize I am not like everyone, a little mark on the receiver isn't a big deal, but I did want to be up front about this. Here is a picture showing what one can expect perhaps after 1000-3000 shells (i'm not sure when the rub spot presented itself). It is obviously not visible when the heat shield is installed.

I've been unable to reproduce this issue. After thinking about it, I suspect the most likely reason would be the OP actually having the stock in the disassembly position instead of a middle position. I've read that there are 2 position stock tubes out there. A discussion here said that Numrich was selling 2 position recoil spring tubes: https://forums.benelliusa.com/topic/7390-usmc-m1014-stock-2-or-3-position/ If they have a 2 position tube, they might be mistaking having the stock near the middle as the middle position. I had wondered if they had possible been pressing the adjustment button with their cheek when shooting, but even if they had the stock would be more likely to rotate the other direction. I also think it would be more likely to happen with the stock completely closed.

Kudos to RxArms for tool less approach. I will never install anything on my M4 that will require tools to disassemble the gun.

Thanks for the input. As for release date, looking like the fall at this point. I think I can bring the cost down more but I’m not ready to say what final pricing will be. I’m also able to get the RMR mount down in price as well, much less than others on the market.
