I am presently toying with the idea of buying a 6.8 upper for my Colt Hbar. Model1sales is the only company which advertises a standard 20 inch configuration. I have been pouring over the forum and I get that some people have had problems in the past and I would like to know what they are so I don’t buy some POS that will cause me problems in the future. Thanks !
Shitty parts of unknown origin. What more do you need to know?
Spike - learn the “search” feature - they dont even have a good rap on TOS. In short, long ago, they were are bottom feeder with M&A etc(they are actually related) for instance, before I knew better(early 90s) I bought their LPKs for spare parts and what would then become a new build. Nothing like bolt open snapping off to give you configdence…TWICE!
That said, not sure where they stand today - maybe have gotten much better and if they resell a name brand item at a good price, your choice on giving them business.
Asking about M1S here is like going to a motorcycle racing forum and asking about a 150cc Vespa.
hey… a LOT of the racers I know love the Vespa!
it’s what we used to get around in the pits…
due to the packs of “rockabilly” kids on perpetually malfunctioning vespas that rove around Portland, i can’t help but hold the position that vespas are hella gay
Poor QC, unknown parts origin, crap parts.
I was in a class that had two guys running Mod.1 uppers and BOTH snapped their bolts within 200 rounds. No shit.
Unless they have changed recently, they run a 1/9.5" twist with a regular SAMI chamber in their 6.8 SPC, which is exactly what you don’t want.
Absolute truth.
200 rds? Holy crap!
[onefromthevaults]Must have been all that fried chicken grease on the parts.[/oftv]
Ah yes! The instructor dubbed them Team Model-1! I remember it well.
I think they were getting all kinds of FTE’s before the bolt bifurcated itself.
Moral O’ Story. Don’t bring an AR to a class that cost less than the class itself.
Whoa Hey Mai! Now that’s funny! 
I thank you all for the insight into the Model1 ARs. I definitely do not need anything that is going to cost me more money in the long run. I am just trying to get a decent 6.8 upper for my Colt lower without dishing out a wad of cash. Hell, I might not even like a 6.8 after I build it!
I have a 16" Stag 6.8 upper. It is one of the older ones with the 1/10" twist and SPCII chamber. My dealer wanted to get one to check it out, and sold it to me for around $475. It’s around 1 1/2yrs old.
The new ones come with a 1/11" twist, and SPC II chamber. You can pick one up for about what the Model 1 would cost, and it has better specs. It will come without M4 extensions, but that hasn’t been an issue with mine using CProducts mags. I like mine so much I am now saving for a 20" Stag Hunter 6.8. You could add sights to the Hunter and it would be like a freefloated HBAR. 
Noveske is showing several different 6.8 configurations in stock.
spend once, cry once…
Ah yes! The instructor dubbed them Team Model-1! I remember it well.
I almost forgot that - Templar, Heavy Metal and I were at that class. Team Model-1 and the “model 1 gang” if I recall right. They were “that guy”
I don’t know how many rounds they had through them before the class, but it wasn’t a very high round count.
I remember, and it was no more than a couple hundred rounds. The look on LAV’s face when he was informed the second bolt was fubared was priceless. Team Model-1 for the win.
After the choice of vendors, barrel length selection came to mind. The 6.8 is the goal in my build, and I toyed around with barrel lengths. The one thing I concluded is the extra four inches wouldn’t pay it’s way.
The 6.8 is a short barrel carbine round already, and there are plenty of ballistic tables out there to show it won’t gain much in velocity with longer barrels. It’s optimized at 16 to 18". Bison, White Oak, and many others can get you set up in that length, you will get what you pay for, and not cry later when it doesn’t break.
What you will also get is a handier carbine to carry and use. As for range and effective reach, paying more for the better barrel with correct specs will get more accuracy and higher velocity.
That’s more important than the length. A SPCII chamber, 1 in 11 or 12 twist creates less peak pressure. You then get to shoot hotter loads.
Check out 68forums for more detailed info. It’s a goldmine for 6.8 enthusiasts and they list exactly who makes the correct spec barrels.
