Just checked this out, Sent email for more info on chamber of 1:10 twist 6.8spc barrel. Says they have 24 in stock. This is believeable, but then I click on the 6.8 upper assembly without BCG, says they have 752 in stock. Now I'm skeptical. If you click on the A3 Dissipator upper, they say they have 99,985 units in stock. BS. Hopefully this is just an error.

The only address listed is a PO Box.

They say their barrels come from either Wilson or Mossberg.

Waiting to see if I get an email back.

Yeah i know who they are and their horrible AK/Fal rep, but I figured how can you mess up an AR build with what appears to be Stag parts. :?:

Listen...I ordered one Saturday 17th off Gunbroker and received it today 20th. It looks just like any other upper AR M4 A3. It came fully assembled. I took off the handguard because I ordered an different one to go on. I also ordered a 6.8 BM to go on the lower. When I get it all together this week I'll tell you how it shoots.

Note: There service is alittle weird (everything is based off email) but so are the other competitors (more or less) based on high volume. Also, I can speak from experience not hear say. :twisted:

Here are the couple of questions I asked and repsonses received

Do you have these in stock? Per website
What chamber do they have? SAAMI or SPCII? SAAMI
If ordered today when would it ship? Within a couple of days

Per the website they are 1:10 twist, so they would be candidates for Paulosantos's reamer If someone is willing to try them. Due to the occurences yesterday with the new MAN in office, I'm tempted to try just the barrel since I can't find one anywhere else & with the extreme coming I'm on a budget saving for that one too. Granted I'd be willing to pay more for a higher quality barrel, I just can't find one that is available. So if you know of one available, you could talk me out of considering one of these very easily.

You missed one question and that is if they are CL or not. If the barrels are CL then you may be screwed no matter what as if the CL is bad you will end up with what Model 1 has or the issue with the last CA barrels. No reamer will fix that. On one of the Model 1 barrels that was blowing primers we tried to put a .268 pilot (.003 smaller then nominal minimum bore spec) down the bore and it woudl only go 2 inch in from the muzzle and hit a solid wall not got tight but more liek hit a shelf. Same thing from the chamber end infact we could not get it to go hardly past the throat if we even maded out of the throat. Same thing a hard stop. I am sure some are OK but you will not catch me shooting let alone owning any of the SAAMI 1:10 1:9.5 6 groove CL barrels sold by the parts warehouses such as these places. If nothing else it will kill any hopes for accuracy.

AR15 / M16 A3 Complete Parts kit LESS lower receiver, with 16" inch M4 contour barrel and A3 Upper receiver. Item # AR-RKM4A368. This 6.8 SPC caliber barrel is 16" long, threaded the standard 1/2 x 28 tpi, and has an A2 flash hider with the correct crush washer. The barrel has a forged A2 front sight base with bayonet lug, not the cheaper cast front sight base which can break. It sports M4 contour and length handguards with full heat shields, and a correctly sized gas port for reliable function. The barrel is machined from chrome-moly, high vanadium steel and hardened to a U.S. government Mil-spec of Rc 26-32. The barrel, and all external steel parts, are manganese phosphate finished IAW 5.3.1.2 of Mil-STD-171, the U. S. government's recommended protective finish for steel. This finish not only looks great, it affords complete corrosion protection. These barrels are of Mil-spec M4 contour (.750 under the front sight base) complete with the M203 groove in the front. This contour is the perfect balance between light weight, heat dissipation, and accuracy. The barrel is button rifled with 6 grooves, right hand, 1 / 10" twist. The 1/10" twist is best for this caliber because it handles the widest variety of ammunition and bullet weights. The barrel is mounted on a FORGED A3 upper receiver with built in Mil-spec M1913 Picatinny accessory rail, with the correct rail numbers engraved, made from certified 7075T6.511 alloy forgings, hardcoat anodized IAW Mil Spec A8625, Type III, Class II, black per No. 37038, Table IX with nickel acetate seal, as per the Mil-spec. The upper features a forward assist and hinged ejection port cover. The buttstock is the current US Mil-Spec M4 buttstock. This buttstock features 6 positions for maximum shooter comfort, reinforced "honeycomb" design for heavy duty use, the correct M4 lock nut, and standard lock plate. All semi auto lower receiver parts are INCLUDED as well as semi auto bolt, carrier, and charging handle. The upper is COMPLETELY ASSEMBLED, and HEADSPACED. Everything you need EXCEPT the stripped lower receiver! (A complete firearm is pictured, the lower receiver and magazine, even though shown in the picture, are NOT included) Add $50 for CHROME LINED barrel and chamber, BlackthorneProducts.com uses FIRST quality parts ONLY , NO "seconds", EVER. Since this parts kit does not include the receiver, no FFL is required. $20 shipping to continental US, +3% for non-certified funds. Manufactured by BlackthorneProducts.com
Thats from their http://www.gunbroker.com auction. Anyone else notice the nice thread size? Tim aparently you have to add more to get the CL version..... Good thing im number 2 on the Titan Xtreme list.... Dont have to even worry about considering this... unless I wanted something to just waste time and crappy ammo with

Notice the 1/2 x 28 tpi threading. How long do you think it wil be before someone blow off there 5.56 muzzle device when they put it on by accident. I wonder if the parts will only go down range or end up in peoepl to the sdie of the line shooting. WOnder hwo big that law suite woudl be epseically when a there is a genral standard of using 5/8 or at the very leas the 9mm threading by STAG whatever that was as I can't rememeber off hand right now. Man if I had write Cand Is offering in that much detail it woudl have been a 10 page document and woudl have required downloading the PDF to read. :lol: :lol:

Some people just have to find out things for themselves. Once you spend time on this site doing research, not just bs'ing around, you realize what combinations to look for and what companies to do business with.

You look for the quality control, and companies who participate in providing a good product, not just buying a pallet of parts and offering them for sale.

Well I took my 223 brake off and tried it on the 6.8...It screwed right on. I did the same to the 6.8. It went on with mo problem . Hell I forgot which is which now. So your telling me I would of shot the 6.8 (atleast I can verify the muzzle hole is bigger then the 223) and all hell would brake loose??

If you can, get a set of digital calipers or something and check the inside dimensions of the 6.8 brake to make sure it is around a .300 whole. I dont know how much over bore they need to be, but I would guess they leave a lil room for error

Most manufacturers use different threads for their 6.8 barrels to avoid trying to shoot a big bullet through a smaller hole in the muzzle device. Something will give in a violent fashion if this event occurs.

Most commonly seen are:

5/8-24 used on 7.62 and 6.8 barrels.
1/2-36 used on 9mm, and Stag 6.8's.
1/2-28 used on 5.56's.
5/8-32 used by RRA on their 458 SOCOM barrels.

I don't have a set of calibers but I was just going to say the 6.8 internal wall is thinner (added space for exit) and the 223 looks to be thick. It seems the inside is bored bigger then the other??

I stuck a 7.62 (M80), 270, 8mm in both brakes and it fit past the neck on all cases. Actually the 223 has a bevel cut inside the wall I was talking about and seated alittle futher down.

Well I would try sticking a .308 or 6.8 bullet in it and see if it fits through good

I have had one for about a year. Their customer service sucks but I have not had any problems with my kit. I have gotten handloads down to an inch at a 100(90 speer and vmax's). My friend bought one 6 months prior to me and his rifle shoots just as well. He also shot a hell of a buck will it a year ago(IdahoJonny's post over on ar15). I was told when I bought mine that it had 5/8x24 threads. Guess I need to go check. Not sure if I would buy from them again based on customer service but I think for the price I did alright. By the way to get those groups I put a JP trigger and freefloat handgaurd. I have also heard the staking on the bolts have been a problem.
