I have a LH T3x in 223 with 1:8 twist.
Had the barrel trimmed to 19.5 inches, fluted and threaded for suppressor. Also spiral fluted the bolt.
Will add carbon fibre stock at some point.
It's my first LH bolt in well over 30 years of shooting and I am loving it.
So far have shot 50, 55 and 60 bullets in it, all factory fodder but am looking forward to reloading for it.
Very happy with purchase.
