Purchased this from sportingservices with intention to get it fluted and use it.
Never got around to it. Only ever had 23 RNDS through it as per barrel break-in procedure in the AI manual
Has standard AI thread - 18x1.5
twist is 1:12
This is an AW barrel and not cheaper AE style that currently retails for over £800. Very Good condition, as new, looking for £500
could consider RFD to RFD at extra charge, I dont live to far from Bisley if that helps and can meet up there.
