  1. Sorry I didn’t see this, but my QD mount is not compatible (I have this buttstock), but I might be able to make a small adjustment on it to work, if I can ever make it work I’ll let ya’ll know.
  2. Doesn’t quite allow a 100% c clamp with cowitness RMR mount, but if it’s a picatinny mounted optic it should be okay. I naturally put my thumb on the 45* surface and I find it very comfortable, my thumb sort of locks into an empty mlok slot.
  3. a little side shot… the front bracket is now at the front of the gun, it is secured by the mag cap and a wave washer. I tried to make it work with the mid gun mount but it had unworkable constraints. If I didn’t care about tool less takedown this project would have been a breeze, but it was non negotiable.
  4. Our 6 position recoil tube is only compatible with the original legacy OEM collapsible stock. So it would work for your needs if I understand you correctly.
  5. There must be a use for the other end. I’m wondering if it fits the recoil spring tube nut? Looks a little small but… maybe?
  6. M4 is more robust. I have all 3, the berettas are a lot of plastic… M4 is heavier but can go through a battle field and still function if dropped, banged around, thrown around etc, to be honest I wouldn’t ever take a 1301 or a 300UP into a battle if the M4 was there as a choice. the berettas shine in sport shooting. Pick your poison.
  7. There are the financial considerations also. A prototype of this piece is expensive, and the market of the SBS I am not sure how big it is compared the 18.5”. Probably a fraction of the market. But I’ll let you know when I’m ready and I’ll contact you. Need to get the first version out before I even consider this.
  8. Haha. Well the SBS is illegal in Canada so I don’t have a way to design it other than deducting the shorter barrel amount from the 18.5” version, and hoping it all works out. I am not in a position to do that kind of blind designing. But maybe in the future.
  9. It is around 7oz. The heatshield is heavy duty 1/8” thick aluminum, to withstand any kind of abuse you can throw at it. OEM handguard is 5oz if my memory serves me right, so total with OEM polymer handguard is 12oz. From the research I’ve conducted, mesa handguard is 0.08” thick, briley is 0.10” thick, our heatshield is 0.125” thick
  10. I’ve also designed an mlok offset match saver. This is a prototype, will be tweaking it still (mostly getting it tighter to the handguard, higher up, and maybe closer to the receiver).
  11. Well it’s been 8 months since initially announcing this thing, had some design tweaks that were needed and I’m happy to say the new version performs excellent. Hoping to get these into production cycle within the next couple weeks, but these won’t be up to sell for a few months most likely.
  12. I also like 7.62, I don’t own any 5.56 rifles… robot warfare would be versatile with slugs and buckshot, can do air targets and ground.
  13. Shotguns are the way of the future, and the past. And everyone thought rifles were the best 😏 Shoot a robot with 5.56 or 12g, take your pick!
  14. The gun rubbed on something or banged something, I know you’re probably disappointed but now your gun is on its way to looking like it actually gets used! I get this is an expensive gun, and I am a bit desensitized to it, since I shoot M4s like the tools they were made to be. Shoot it and enjoy it. Run her hard, enjoy all she has to offer. if it really bothers you you can try some Birchwood Casey Aluminum Black, it might work for you.
  15. This thread got off topic a bit, but talking about how I usually carry my M4 (in the woods on my hikes and walks). No shell in the chamber, but I have a shell on the carrier, all I have to do is rack the bolt and I’m good to go. Just one way to go, but when I’m with my kids and dog, I don’t want something stupid to happen with a loaded shotgun in battery and would rather have a quick rack of the bolt to get my shotgun ready if I ever need it.
  16. Was your barrel fully seated and tight? Might be a cause if it loosened itself. as the comment above I have shot thousands of slugs through the M4 stock choke, even though they say not to… (apparently)
  17. I’ve had to redesign the heatshield unfortunately. Problems started to occur after 1K rounds and had to go back to the drawing board after a few months of trying to remedy it. Hoping to have a whole new prototype for testing in January Feb.
  18. Benelli would do well to apppoint a regular member with reputation to have low level admin power, honestly. What a crap shoot. a velocity filter would be useful, stopping members/IP from doing more than 2 new posts an hour or something.
  19. 15% off all our M4 gear this weekend. First sale I’ve ever done! rxarms.com
  20. I think the worst that can happen is a round will fire, bolt goes back, recoil tube dislodges, your buttstock comes off with a bit of force. I don’t think there is any real danger other than that, the bolt can’t exit the rear of the receiver it will just impact the back of the receiver and will be contained. if this were to occur I think you’d have warning signs, such as a slightly loose recoil tube before it happens. I’m glad you got it sorted out! Sounds like it will work just fine as you felt the torque of the nut was sufficient.
  21. Wow thanks for posting, I don’t take down the bolt at all if everything is working well, but I might start cleaning it more often once a year as you say.
  22. Movement is normal, the sound looks to me like the buttstock pin is compressing a bit, then releasing when it seats back into the groove, causing that sound. I don’t believe it is out of spec, but maybe some others can chime in regarding the sound.
