14.5" Grendel barrel with midlength gas OK? - m796rider - 03-31-2016 Hi all, I am thinking about cutting my 16" Alexander Arms 6.5G barrel down to 14.5". The barrel has a midlength gas system. Do you think I'll be OK without having to mess with the gas port? Thanks! 14.5" Grendel barrel with midlength gas OK? - Heinz57grendel - 03-31-2016 or you could sell it to me. 14.5" Grendel barrel with midlength gas OK? - Beerswimmer - 03-31-2016 I had a 14.5 midlength 5.56 that was great, I think it'll be fine. Now you can get that barrel threaded properly 14.5" Grendel barrel with midlength gas OK? - LRRPF52 - 03-31-2016 You'll likely need to open the gas port, especially for cold weather and lighter projo weights. 14.5" Grendel barrel with midlength gas OK? - Keep The Change - 04-01-2016 I know my 5.56 Noveske middy works just fine. However I don't know if there is a difference in gas port size from a carbine to middy on a 5.56. I would think if the gas port size on a 5.56 is the same between the carbine and middy that it would be fine for the 6.5 Grendel. But like LRRPF52 said, it might have an issue in cold weather. 14.5" Grendel barrel with midlength gas OK? - m796rider - 04-01-2016 Thanks all! 14.5" Grendel barrel with midlength gas OK? - LRRPF52 - 04-01-2016 5.56 has way less bore space, so you can get away with a lot more with it compared to 6.5 Grendel or 7.62 NATO. I have a Model 605 Retro with RLGS and 15.75" barrel that runs great so far, never choked on me yet, but I haven't really tortured it. I'm thinking about converting it to Grendel for a steel cased blaster, since I rarely shoot it now. If I do that, it will have a concealed MLGS for sure. 14.5" Grendel barrel with midlength gas OK? - Keep The Change - 04-03-2016 Yeah good point on bore space or volume on a 556 versus Grendel. I guess the thought is with the additional volume in the bore the pressure is less than the 556?
