Hi, I'm new to the forum and have been a Grendel fan for years.
I have an AA arms 6.5 Hunter with a Shilen 19.5 in barrel. I want to free float the barrel with the goal of decreasing the group size or at least gain some group consistency. Currently I'm getting about 1.5 moa with 123 SMK and 30.3 gr 748. The groups will string or I'll get an flier in a 5 shot group. I've got a decent trigger and a 3-10 Leopold mil dot. I have t take off the FGB to install the float tube so I would like to upgrade with a clamp on.
As most of you know, the barrel bulge in this barrel for the FGB is .906 diameter. The only low profile gas block in .906 comes from Triton and is held in place by a set screw and probably blue Loctite. If I'm going to change the current FGB which is taper pinned along with blue Loctite, I would like to install a clamp on FGB. I'm unaware of any manufacturer that makes a .906 diameter low profile clamp on FGB so here's the choices:
Take off the barrel and reduce the barrel bulge to .750. and then use a .750 FGB. I'm hesitant to do this but would consider it.
Buy a .936 clamp on FGB and then make a .015 thick cylindrical sleeve(.030 total) with properly located port hole and place it in between the .906 barrel bulge and the .936 clamp on FGB. probably use blue Loctite between the FGB and sleeve. Also place a cut along the sleeve length to allow for the clamping action of the FGB to act on the sleeve.
I'm planning on using 1020/1026 steel for the sleeve.
Do you think this sleeve would or would not work? Any other ideas?
I have a 28" lathe with a 3 jaw chuck and also a knee mill.
Thanks!
