Posted: 5/2/2012 10:09:54 AM THE IMAGE ABOVE IS A PAID ADVERTISEMENT I picked up an used 6.8 SPC short barrel and just realized it is threaded for 1/2x28. I had hoped for a Troy Claymore but I don't think the 5.56 that it is threaded for would work with the closed end. I could drill the end out a little but I don't know if that will affect function. Any suggestions for something that will work with pushing the blast downrange a little?

Even for the 5.56 there is plenty of room for clearing the 6.8 but double check to be sure they have not changed since I measured. I have a .338 Spectre barrel and the 5.56 KX3 cleared it but just barely, so I went with the .308 version which gave more than enough room to clear the .338 bullet. Still works like a champ.

If it's 5/8ths - 24, a 308 muzzle devise should work. But, I'd still check with the manufacture to verify.

I don't think I have ever seen 1/2-28 threads on a 6.8 barrel, I'd much rather have 5/8-24.

The claymore looks like if it was bored out enough for a 6.8 it would have little skin between the bore hole and vent holes around it. .

I used a YHM Phantom 5C2 and drilled it out 5/16, or .3125, which is .035 over bullet diameter and that is more than enough.

Besides options listed above - Vortex 1009V PWS FSC Custom PWS Step Down Adapter. Then you can use any 5/8x24. This is what I did. ETA - D-D beat me to the Vortex.
