it looks that way in some pics but the barrel is very slender. the muzzle is 14mm (0.550") diameter

and thanks guys I'm pretty excited how it turned out.

ive been working on this rifle a little over 5 years now. (i made a thread on CGN Nov 22 2020 but at that point i already had the receiver CCH, the barrel and barrel nut finished)

i cant wait to get a range report for this rifle. i have some 129's, 140's and 160gr bullets to try in it
