This may be a silly question, but any reason I shouldn't get one of these?

I got a chrome lined 16 inch one through Bravo Company and have had my share of issues, but that is to be expected from a new caliber. Model One most likely did not even have ammo to test out their uppers before they went to market. And Brovo Company has been there to help out along the way.

First I had extraction problems so I tried a Defender and extra power extractor spring. Then I ended up fixing the problem with a PRI Fat Boy gas tube. This helped with recoil anyway.

Then I sheared two lugs off of my bolt. It may have been my hand loads, or it may be an inherent problem with the larger bolt face, or it could have been a bad bolt. But Bravo Company replaced it no questions asked and in a hurry.

Be advised it may not be perfect out of the box. Having said that, I do not regret buying from Bravo Company

My friend Woden has a 20" Model 1 6.8 Upper. I helped him sight it in and it shot awesome. He didn't have a lot of ammo but we didn't have any failures. We're going to take it out on Saturday to run some more rounds thru it. I'll let you know how it goes.

They seem to have the best price on 6.8 barrels by far, and I'm really keen on testing out the calibre. I have a RRA national match lower and a spare A1 upper that've been waiting for a project. Is it a different bolt?

The 6.8 SPC requires a 6.8 bolt.

I'm interested in reports on the Model 1 barrels, also. I have a stripped upper on the way, already have a parts kit for the upper, and was planning to pick up a carrier and maybe a bolt at the next show, so I'll be looking for a 6.8 barrel in a month or so.

Woden and I will post a range report this weekend.

Bravo and M1S both get their barrels from ER Shaw.

I too have the 6.8 16 inch upper from Bravo which is a M1S barrel. With this you will need to add on the pri fat boy and do something with your extractor. I just added an O-Ring. After doing this the rifle runs perfectly. BTW, the barrel itself easily shoots MOA even with a cruddy shooter like myself.

I have three Model 1 chrome lined Barrels / uppers one 16' and two 20' all of them work perfectly and are extremly accurate. The only modification is the crane O-ring under the extractor. My 16 "
shot a .41 inch group at 100yds. with a 3X9 Leupold on it for testing

I have had excellent accuracy and performance from my Model "1" Sales 6.8 barrel and bolt. It is a CAR style 16" barrel and easily shoots 1 MOA all day long. The finish is a nice even mil-spec looking phosphate and the crome lining looks good and performs good as well. I highly recommend them as a budget alternative.

What are the barrel threads on the end of the barrels cut to (for the flash suppressor)? Are they the standard 5,56mm type or are they the larger size?
Link Posted: 7/29/2005 7:18:33 PM EDT
I believe that they are threaded the same as 308 barrels.

some are 1/2X36 don't know about all manufactures

From what I've read, the military specified 5/8"x24 for the 6.8SPC muzzle, but there seem to be some barrels being made with 1/2"x32 and 1/2"x36 (haven't seen anything saying who is making those barrels).

Anybody check their Model 1 barrels to see which thread they are using?

Has anyone tried the 14.5" M-4 profile 6.8 barrels from Model 1 Sales? They're more expensive than the 16" 6.8 barrels, but would probably make an interesting M4gery project (with a 1.5" flashider).
Link Posted: 8/1/2005 4:21:46 PM EDT
I'm about to start a build w/that profile. It may be a while but I'll tell you how it works out.

Where are you getting your PRI fatboy gas tubes and Crane extractor springs??
