This. And since they already have a .308 on an AR upper, they could just add a side-feeding SR-15 magwell on the side. And then downsize it, and make it take side feeding AK mags. |

I’ve wanted to do it ever since the Colt LE-901 came out but I lack the engineering skills required to do it. It’s my dream to have a portable 308 that isn’t a 240, something easy to carry like a MK48 that can run a FRT or super safety. |

I think the markets is a LOT smaller than for a 5.56 version Most people won't want to spend twice as much on ammo to shoot the same beltfed they already have in 5.56 But I fully encourage someone to make one, Lima6 said he would after the 5.56 is done. Which is good. Cuz I want the 5.56 |
We're gonna need pintle mounts.

Cryostructure is working on it but they have a lot of irons in the fire. |

I made a trailer hitch mount for sitting on a tailgate or in the back of an SUV/minivan, and a stand-up tripod that is lightweight and bolts together. You just need a tube that this will fit into, weld it in the end of the tube, and drill/thread a hole in the side of the tube for a bolt to go in and lock your 30/50 into the bushing. If you weld(or 3d print) a handle onto the bolt then you don't need any tools to set the gun up. Picatinny rail adapters can be 3d printed, or buy a cheap, tall red dot mount and drill a 5/8" hole in the side. Clamp it to the bottom of the rail and bolt it to the 30/50 pintle |

That's not bad at all then. Got a pic of the trailer hitch setup. That might be neat on a tailgate. |

Yes thats a bold claim lol. |

| im still not convinced i need to add a belt fed ar10 to my lineup. please add a link to the cheapest, most reliable bulk ammo for that so i can weigh my options. last time i tried to buy bulk 308 ammo i ended up buying 223 instead. |

There's a lot of 7.62x51 stacked deep out there. What's in short supply are (talking FA here): 1. HK sears and trigger packs 2. Registered receiver HK's, which eventually stretch to the point they won't function 3. Pre-86 M60's 4. Pre-86 M240's 5. MG3/MG42's which eventually stretch to the point they won't function 6. M14's and FAL's, which are not reaonably controllable in FA 7. Pre-86 DP28's, PRK's, whatever else 30 cal foreign sourced (not necessarily 7.62x51 but maybe backwards compatible) M1919's are the most prevalent, but IMO kindof clunky. Heavy, oversized, and typically tripod mounted to work. If I ever see a M1919A6 configuration in FA I'd like to give it a try, but haven't seen one yet. Maybe that's a message, right there. The gold standard is a FA component like a HK sear, that isn't a wear part. Maybe someday Ukraine War ends and the flow of steel.case 308 resumes. That's what most HK guns run best anyway, in my limited experience. Hope this response doesn't get the thread moved or locked... |

trobertson5-0 I wasn't put in jail for what I did. I was put in it for what I think. There were FBI agents posting in my threads. I've seen the discovery showing this.

If you're planning on getting a belt fed .308, now would be the time to buy some links. Not after the Lima Six prototype is shown. I bought 10,000 5.56 links WAY before the Shrike and the M249s came out....they were $20 per 1,000. Tony |

I had a decent little stockpile (for not owning a 308 beltfed), but a nice man with a minigun let me burn it all up last fall. Worth it |
