I have a Wilson Combat TTU single stage in my WC 6.8 SPC Recon.
There is no creep whatsoever, no overtravel, just a clean glass rod break and an instant reset. When I let people check it out they all comment on how nice it is, usually along the lines of “ooh… that’s NICE” with a big grin on their face.
I have used Rock River National Match, JP, Gieselle, Timney, etc.. in ARs.
My LTR 308 has a Jewell and while I have it set lighter, the TTU is every bit as nice.
It has never failed to ignite a primer, including CCI 41 Milspec.
- zero creep
- no overtravel
- instant reset
- None, other than it makes me want one in every lower I use
