  1. Ah thanks, I needed the properly terminology for the APE. I need to check the DE back because I'm pretty sure it was a spring loaded pluger, not unlike yours on the Steyr claw... the DE really is an interesting gun, completely stupid and unpractical, but god it's cool and worth having one for the cool and engineering factor. The F7? That thing with the gigantic lower and the upper being basically a rail segment with a ring for the barrel? I love that stupid thing. It's certainly an easier approach than to overmold and entire proper skeleton like HK should have done, fine tuning it
  2. I've heard before of the threat prohibiting weapons in the region and assumed that 1: it's BS and 2: If it wasn't no one would give a crap because it's stupid... reality sure can be weird.
  3. Yeah, a lifting chamber is pretty much granted. But there are several ways to accomplish it... it would be hilarious if in the final iteration of their design they went for a Steyr ACR style with the locking roller. They certainly got rid of some of the bulk, that little protrusion near the magwell is gone in the last gun they showed us.
  4. Really impressed by the F-4, very clever layout, specially the offset recoil spring and guide rod assembly, as well as the asymmetrical lugs, the use of the Desert Eagle anti-rotation device (did it appear in other guns before? As said on these forums, the Tavor is similar, but it uses the guide rod instead of a dedicated spring loaded plunger.) Thanks for sharing your design, it was very useful to me as it showed the strengths and weaknesses of my own design. Keep on the good work. Only thing I didn't really like on your design is the lack of space magic BS... you need
  5. Yes, I have read the paper, but it has been a while so I probably forgotten stuff, so a re-reading is in order. That goes for the interview as well. I knew Textron was using a compacted powder bed, but it sounded so weird I wanted confirmation. Doing probably simplifies the molding process and does not lock you into a specific bullet shape. I think I'm starting to understand the reasoning behind it. As for the action displayed, I'm also aware of them. To be frank I haven't paid much attention on the LSAT or MGs in general, more interest on the rifle and rifles in general. That VPN'
  6. Awseome, thank very much... now to the dissection table! PS: It's so SO good to see proper 1913 rails modelled properly... no weird angles, heights or other BS.
  7. Yeah... at a first glance it doesn't look good. I still wonder what kind of freestyle accounting is going on at Haenel for an AR style gun being cheaper than a gun with an extruded upper and injection molded plastic lower. Albeit that is only part of the equation for a contract like this.
  8. I don't think anybody was expecting that result, myself included. From what I could gather from the news and from talking people in the gun industry and German speakers it appears to be solely a case of "it meets the requirements... and is cheaper"... which itself raises questions about the result, considering the size and ownership of Haenel, some even going as far as calling it a shell company for Caracal. How much of that is true or just "foreigner man bad" I don't know. As for the rifle it's quite sad to see a new design fail, even if it also met the requirements. For the Haene
  9. So, for a while I've fascinated about Cased Telescoped Ammunition (CT ammo for those weird people that like acronyms), after, of course, laughing at the idea like any uninitiated simpleton (dum fix wat aint broke!) until I actually understood the idea and a presentable firearm came along and caught my interest, the current iteration of the Textron carbine/rifle/whatever in the NGSW program... because until this point all small arms examples were either goofy as fuck (Dardick), stillborn (Ares AIWS), or weirdly specific (Steyr ACR being and open "bolt" flechette gun.) Then I researc
  10. I really need to dust off and copy, fully embrace the tism and actually beat the first couple of missions, I always so the concept as immensely cool but never had to time to commit fully.
  11. It's a shame that most useful gun files, including yours, have been yeeted from Grabcad... if it's not asking much it would be awesome if the F4 files were reuploaded, perhaps in a cloud or something like it. Regardless of that I would like to thank you Sturgeon for all of your work so, it has been a great inspiration for me, specially in regards to more aerodynamically efficient projectiles... so much so my final ME bachelor's project has been on the subject. You also inspired me to try to make my own rifles, if anything it's a great exercise in modeling and material s
