Basic tuned trigger or Williams Set trigger?

Perhaps I should have left the caliber out of the question. I was really considering the 6.5 at first but uppers all seem to be months and months away with it.
So back to the OP. (If you know of a builder that could put together a Mk12 Mod 0 6.5mm grendel upper for $1300 or less by summer let me know and I'd consider it.) |

I'm happy with the LMT 2-stage in my clone but I have to admit the Geisselle in my patrol rifle is really nice.

6.5 Grendel would be much better for a precision build. And the reason being? (I am anxiously awaiting the popular tripe which abounds in these type of posts)... OP, Geissele would be my choice. |

OP, Geissele would be my choice. he could be a Grendel snob then I have 3 spike's two stage and cmmg and they are pretty nice plus with my 6.8's I can dump a 30 round mag without jammin |

Depends on your budget.
If you want a single stage inexpensive option sent it to Bill Williams and he can make it 3-4 lbs and no creep, all for $50. If you want a 2 stage the Rock Rivers are hard to beat at $100. You can always spend more, these 2 work on my guns so I have seen no reason to spend more for a drop in unit. |

Sectional Density So the bullet is made of tungsten? Seriously, post some numbers of like weight and like kind bullets. ok check this, I myself am buying a 6.8 because i need the bigger industry support and am going with a shorter range weapon 0-300 or so meters, but if building a longer range rig which I assume is being built since it is a mk12 mod 1 clone or likeness here are some numbers i found.....i picked obviously the grendels best bullet the 123 scenar and what i think is a great 6.8 bullet for retained velocity yadda yadda...someone chime in with a more impressive bullet for the 6.8, the 110 grain vmax , this is some data pulled from 16 inch barrels, the vmax is what i see some people getting from handloads hornady lists it at 2550ft/s and the grendel data is from alexander arms website, the difference gets quite noticable after 500 yards, 6.8 ........................Grendel ft/s energy 0 yards 2620/1676................2480/1680 100 yards 2381/1385...............2345/1476 300 yards 1942/927................2031/1127 500 yards 1559/593..................1761/847 |

I would use the 129gr Hornady SST in 6.5mm vs. the Sierra 130gr SBT, which are the loads I checked against one another (see above)... ETA - Oops! Forgot that was a different thread. Hang on, let me copy/paste the info here... 6.8 SPC also has similar BC bullets available for long range shooting compared to the 6.5 Grendel (in the same weight ranges). The "more bullet choices" part is really mostly bologna b/c you can only load the rounds to a certain length, which immediately limits the 6.5mm bullet selection. The same can be said for the 140-150grn weight bullets for the 6.8.
I can say this, my 18" WOA can propel a 130gr Sierra SBT to 2522 fps (+/- 19fps), whereas the 6.5 Grendel needs a 24" barrel to produce 2470 fps with a 129gr Hornady SST. I also know that the 85gr Barnes TSX is getting close to 3200 fps in my same 6.8 SPC barrel. Both the 6.5 and 6.8 are intermediate distance cartridges at best (both also much better than the .223/5.56 NATO). If you want real long range performance (that's 600+ yards), then get something in .308 Winchester/7.62x51 NATO. You can't ask a teenage boy to do a man's work all the time... |

There are a few 6.8 bullets like this (finally), but they are few and far between (GS Custom Bullets come to mind). Anyway, out to 300 yards, there is not going to be much difference at all, period point blank. If you need longer range bullets or weapons, the 7.62x51 is out there. I love my .308, I must say, but I like the weight of the AR-15 series rifles... |

Hijackers! Exactly!!! Back to the OP people. Why does every 6mm thread have to turn into a number crunching pissing match?? Frankly I am mostly interested in hunting and having a nice rifle in case SHTF. The 6.8 seems easy to buy a can for too. That and AR Performance is like 1/2 hr away. |

BTW I pretty much decided that the Gieselle (sp?) DMR is what I want. I wonder how well it would work with a .22lr dedicated upper to be a close trainer for the regular upper.

I love it. It's fun and economical. I get to use the same rifle, same trigger, same weight, etc all for about $10 per 100 rounds instead of $40. |

BTW my caliber is settle, I just ordered the upper in 6.8mm. I think its the better choice for my needs.
So by mid July hopefully I will have a 6.8mm Mk12 Mod 0 in 6.8mm and the deer and the antelope will have something to worry about. |

My local gunstore carries 6.8mm SPC ammo if I need it. SSA carries everything I need ammo wise including nicely priced brass. It will be easier for me to suppress. I have a local builder that was willing to build exactly what I wanted. We had to make adjustments to the Mod 0 concept for it being 6.8mm but they are small sacrifices. Who know's maybe I'll end up getting a grendel too, but not today. |

Excellent choice, Harrison is the only one I will use to build my rifles..... |

Excellent choice, Harrison is the only one I will use to build my rifles..... I really like the fact that he is basically local to me too. I can't wait, this is going to be a kick ass rifle. My other goal will be to get the YHM phantom 7.62 suppressor for it and build up a .22lr clone upper (Model 1 sales I think) for cheap practice. For glass I have been eyeballing the 10x Super Sniper or the 4-14x Falcon Menace. |
