Had a few .223's over the years , one that sticks in my memory was a very nice Tkka M595 - far more accurate than i was , current .223 is a remington lvsf - thats "light varmint stainless fluted" (bit of a mouthfull i know ) had it about 6 years now , B&C plastic stock and a medium contour / weight fluted barrel , the only thing i dont like about it is its blind box mag (prefer drop mags), the only work its had done is the sear / hammer stoned / honed , as ever shoots far better than i can , light as a very light thing - i dont even notice i am carrying it (i am not kidding) and it shrugs off water like a duck , i think the twist is 1 in 9 - but as i only use it with 55g heads i would check that ,long since deleted from their line up you might be able to find the odd new one lurking at the back of a dealers shelf or good secondhand pop up now and then , mines a keeper - which for me is unusual .
