    Looks very nice.

    I went to push it into my Aero Precision upper and it didn't want to go in all the way - the "alignment post" was a good 1/4" from the notch in the upper. I tried putting some Weapon shield on with not much more luck. I then tried Weapon Shield grease - and it went on a smidge further, but still won't "slip" in.

    I checked the fit on my Combat Armory stripped upper and it's a tight fit on that one, but goes in closer to the notch.
    The Combat Armory barrel slips right into the Combat Armory stripped upper.
    I tried the Combat Armory barrel on the Aero Precision stripped upper and it wouldn't go in.

    I started Googling the issue and I see that I'm not the only one to have this happen and with various brands.
    It's suggested to heat the upper and that usually allows the barrel to be inserted.
    I'm half afraid to try for fear it goes MOST of the way and gets stuck there.

    I suppose a mallet may do the trick. I've always had someone else install the barrel onto the upper for my builds because I don't have a vice/block to hold the upper, but I've always test fit the barrels in the uppers, and while some have taken a few twists and wiggles to get the barrel into place, this is the first time I just can't get the barrel slipped into the upper.
    I’ve had a few like this as well as gas blocks. While I do have receiver vice blocks, I’ve used pieces of wood and a mallet to encourage the gas blocks and barrels to seat properly. Pre-alignment is key in order to avoid using a thick wood dowel to punch it back out. Wood between the mallet and barrel will protect it. Direct heat on the front upper will help. Tight fitting of these two parts is a good thing.

    UPDATE:

    Barrel is now fully seated in the Aero Precision upper. Heated the upper and gave it a whack with some scrap lumber.

    Hand guard is ordered. Aero Precision ATLAS S-One 7" blem direct from Aero Precision.

    I was looking for some sort of flash can or linear comp for this 7.62x39 pistol build.
    I'm going to try going without the expensive PWS CQB comp first to see how it goes.
    Wanted something different than the run of the mill KAK flash can.
    Found this.

    It's machined from a chunk of steel, so it's got some heft to it. Not sure the actual weight.
    The inside is a smooth, continuous cone shape.
    It's nicely machined and finished - pics don't do it justice.

    This is what I initially had in mind. Not sure something workable exists.
    I'm not well versed in the various thread sizes - whether adapters exist - etc...

    Here's a 1/2x28 to 14.1lh thread adapter. I'm not familiar with the above Chinese brake or its thread pattern.

    This is awesome, but not long enough to reach out of the hand guard. Wrong threads too.

    5/8″-24 TPI Right hand thread - I guess. That's the size muzzle device I ordered and it threads on properly.

    Yeah, I know. That's why I was looking for that "look".

    Every bastard and his mother with an AR15 has a KAK flash can - I wanted something... different.
