    I have a new Satern cut rifled barrel

    I couldn't resist, Satern has barrels available to buy, in stock. I have a standard type profile one so I thought I would try an 18" heavy, .873 at the muzzle. I've never built a rifle with such a large profile barrel so I have some questions.
    The gb diameter is .875, with a lopro version can I still use a normal gas tube? Any recommendations on uppers, I've had good success with Mega both forged and billet, but thought I might try something different. I've never glued a barrel in but because of the barrel weight I may do so on this one. Any thoughts?

    Before anyone brings it up, let's avoid the whole debate about barrel chambers and your feelings on Satern in general please. 😎

    Sadlak makes a nice lo-pro .875" gas block. http://www.brownells.com/rifle-parts...265-80917.aspx

    Can you measure your gas port diameter please and post it?

    I have an 18" Satern fluted MLGS with .750" journal, 9/16x24 muzzle.

        I went with an adjustable, for function as well as having read the gas port is oversized.

        Rather than gluing or blue Loctite consider using something specific to the application:

        Loctite 609 Retaining Compound, General Purpose, Green Color (made to fill cylindrical spaces)
        or
        Loctite Green 620 High Temperature Retaining Compound

        These are for loose tolerance press fit bearings and such.

          Green Loctite is what I had in mind. I use it on gas blocks and tubes since I have terrible luck getting ones that fit snugly. I had not read about the gas port being oversize, I'll make sure to measure and share the results. What should it be on an 18" midlength?

            From a post back in November 2015:
            "The biggest consideration is the MLGS gas port, which is too larger at .094" on an 18" pipe. That's simply way too big, should be .076"."

              I pulled out the Mitutoyo to check and the battery is dead, but you guys are right a 3/32 punch fits the hole. Never thought to ask. Looks like I'll be buying an adjustable gas block, or sending the barrel back. I seem to have read somewhere a .875 adjustable gas block does not fit under most free float rails unless it was designed for a 308 size rifle, they're too tall.

              It.

                Call SLR Rifle works to see if it work. They should be able to tell you since they sell both.

                    Seekins Precision rails are 1.8" they will probably work for a rail.

                        I have to say that I love my Satern barrel and have had a very good experience with Satern customer service...

                          Are the Brownells barrels that are made by Satern of the same quality?

                            There are essentially 2 different barrel types made by Satern. Their cut barrels are sold as Satern brand. They also have their Liberty barrels, which are button rifled. The cut rifled barrels tend to be more accurate, and are correspondingly more expensive. The Brownells barrels are the Liberty barrels, afaik, as are the AR Stoners, sold by MidwayUSA.
                            If it's true that we are here to help others, then what exactly are the others here for?

                              I have this barrel as well and actually returned my SLR gas block because it wouldn't even fit my SLR rail...so, make sure you pay attention to the schematic they have posted. It looks like it will fit but after I talked to them they said it wouldn't. I'm stuck now trying to find an adjustable .875 gas block that will fit a rail. Other than that my build will be complete. Any suggestions for the OP and myself?
