Ok so if a man wanted to build a SBR 6.5 G upper.... what is the barrel of choice ?
The Flaxon 12inch ? |

[#7]
What is typical bolt life? That's what kept me away from 6.5, 6.8, and 7.62x39 AR's. I do want a .300blackout, or 5.

LaRue has SUURG complete uppers meant to be sleeved over with a specific suppressor for that upper. Precision Firearms will make any length you want, from 7" on out, with Criterion, Bartlein, Krieger. Ballistic Advantage has Hanson 12.5". Odin Works has 12" with tunable gas block included. I'm already looking at another short barrel for my next pistol build. I'm thinking shorter even. A pistol Grendel is really an omni-role blaster, capable of HD, hunting medium game, long range (at least to 800 with solid impacts on steel that can be seen/heard), car gun. |

Anyone play with the ~100gr bullets? I feel like they make a lot of since under 600 yards. Just wondering between the 108 scenars, 107 TMK or 100gr ELD which I should try first

Just wondering between the 108 scenars, 107 TMK or 100gr ELD which I should try first View Quote I've done load development with 107gr SMK, which is a great 100gr-class TGT bullet, low recoil, good BC, good muzzle velocity. I've also done 100gr Nosler Ballistic Tip for a lighter hunting bullet. 108gr Scenar is the same cup, but different core weight as the 123gr Scenar, so they look the same from the outside. Another really good TGT bullet line is the Scenar-L. I have a bunch of 107gr SMKs, which I will probably mass-produce with 8208 XBR in the near future for the pistol and my 17.6" Lilja, and my 18" LaRue Stealth. I also like the 95gr Lehigh Controlled Chaos. Feels like shooting a 10/22. |

Yeah, I am using the more powerful Maxim Defense short RET action spring, which is very stout.
It provides a lot of return-to-battery stroke for positive feeding of the action. Out of the gate, it was 100% with Hornady American Gunner 123gr unsuppressed. My main interest in the Federal 90gr TNT American Eagle load is HD and fun closer range TGT practice for new shooters. In both of those scenarios, it will be suppressed. For my hand loads, I'll most likely being using CFE223 under 95gr VMAX or 95gr Controlled Chaos for HD, and that powder will hit the gas port with more pressure and volume based on everything I've experienced with it over the years. |

The PSA 6.5 Grendel has only been on the market a few weeks but first reports are very positive. If I wanted a 6.5 Grendel I would consider a barrel or upper from PSA.

I’m thinking about hitting up PSA for their 12” pistol upper. Not sure it’ll be a real tight long range shooter, but It should be a fun blaster and decent hunting pistol.
