Thread: JW15 piece of shit

The JW15's are generally a solid bit of kit, sturdily made and shoot quite well, but the difference in individual rifles is in the quality of hand fitting and finishing which can vary from good to bad. The eccentrity of the bore is a fairly common thing in rifles and is of no real consequence in a field grade .22. Eccentricity of the muzzle and crown is a different thing altogether and needs to be corrected by shortening and recrowning correctly, recutting the suppressor thread accurately at the same time. Any competent gunsmith should be able to tune one up to give good performance. In my experience they are capable of 1-2 MOA which is pretty good in .22's.
