I just recieved my new LMT upper, a 16" upper (NOT SBR). But it is definitely a shorter barrel, how can I tell if the flash suppressor is permantently attached? Does LMT do that?

Thanks. I just hope I have the right part, as the invoice has the part listed for the 16" upper.

There should be a small weld or silver solder meaning instead of a right angle where the FH meets the barrel, it is slight smoothed. If you have a small dowel or cleaning rod put it in the barrel with the bolt closed, mark where the FH is remove, and measure. If the FH is not apparently permanently attatched measure to where the end of the barrel is.

Good luck.

LMT's website says they blind pin the flash hider, then weld over the pin entrance hole, then grind flush and finish. The bottom line is that it will be very difficult to detect where it was pinned. Your best chance is to look carefully at the flash hider to see if you can detect faint grind marks or finish discoloration where the weld is.

Good info, didn't know that.

I have a BM upper that has a 14.5 inch barrel and had a pinned and welded comp. I removed it with a Dremel. It was very difficult to find the pins, even after grinding into the material.

For others who attempt to do this themselves, grind around where you think the pin is, and then take a wrench to the compensator and torque it back and forth a couple of times. If you did it right, you will now be able to see the pin. Now it's as simple as cutting a slot on either side of the pin, so you can get some needle nose pliers in there and pull it out.

ETA: (For all the JBT out there) It now sports a pinned and welded Phantom, courtesy of Eagle Firearms, bringing the barrel length to >16 inches, so BACK OFF.

Where on their website? I can't find it.
