Can I please ask for some advice, I have an A.I. AT in .308 with an A.I. 26” barrel from factory, the rifle came with an additional 20” A.I. .308 barrel, un used.
- Using the systems quick barrel change feature would I have to:
use head space gauges to check tolerance every time I swapped the barrels as stated in the A.I. manual, I understand the reason for this as it was normally conducted by our small arms armourers (or is this A.I. covering themselves which is understandable).
If I do need head space go/no go gauges, are the A.I. ones any different in size within the SAAMI tolerance to a less expensive .308 gauge set?
If a failed no go check occurs how do you then vary the headspace as the manual states tighten the barrel to its stop, then secure the retaining bolt; there is no mention of how this is ‘tuned’, once again our Tech Team conducted this activity.
Or do I just follow the numerous shop/AI owners and engineering providers who have posted YouTube vids and just screw the barrels in tight and as they are both A.I. they are set for head space once the retaining bolt is torqued correctly.
Of course if you are kind enough to advise none of your advice will be culpable going forward, so no accountability lol.
Thanks for the great forum to date I look forward to your reply and hopefully some clarification on a grey area of my skill set.
