Happy birthday to me, my barrel showed up today. A few more details and the 652 will be completed. Anyone here ever find out what is on the lower of a 652 or 3? If I cant find anything (and I have not thus far) its going to remain on the modern lower (for those that are A.R. about things and wondering)
BTW with a 14.5" barrel it comes out to be exactly 16" from the bolt face to the A1 housing with a standard old style lock washer, 16-1/8" with a thick one. its going to be pinned so I don't have to give the government any more money to have my freedom on a technicality (rolling eyes) 
next to my XM16E2 SBR

Auto selectors are in route with correct lever, trigger guard, mag release and charging handle need coated to match the body for sure. Think i'll re parkerise the pins when I swap the selector out, did this to the other hardware, should have with the firing/trigger lins too . Shinny black is not a good thing. Details details minor however

Nice build though, love the look of these and the light weight doesn't hurt either! |

I use my cleaning rod, and measure out with no less than THREE separate measurement tapes to make sure its 16! Not all measurement tools read the same! Once marked I place the rod down the barrel until it hits the bolt face (same way the ATF does it) Then use a knife edge laying across the end of the flash hider to intersect the rod, this is where they will measure to and from should a question come up. Mine with a Double star 14.5 pencil barrel and a thick split washer came out to be 16-1/8 pined and welded it. DONE!
