Thread: Switch barrel : any experience ?

Yeap ,

And the new AIs use a smaller allen key than that , to do their barrel swaps , and its held inside the stock cheek piece .

Good to see they're learning. Hopefully they avoid the plastic washers

Not quite , most AIs ( exception was the AE , no longer made ) , donot have a seprate recoil lug , so like some custom actions , there is not way a seperate recoil lug , pinned or otherwise to move or fall out , during barrel change .
Also like a lot of target rifle actions , the AIs have a very long barrel thread in ( tunion ) , its 38mm long , most sporters are only 13mm , the Rem is abit longer at 0.75 or approx 18mm , so that and the fact that the action is solidly ( 4x bolts ) , and permately bonded/glued into the alot chassis/frame .
In short the action & chassis are bonded together for ever , all other stuff is removable & replaceable , from the locking ring insert inside the action & bolt ( either just the head or complete body ) .

IF the locking ring gets too worn , simple , pull barrel out & then just push the ring out , new ring & bolt and the rifles back to like new , a shooting range in the USA , had over 100,000 rds thru a AI AW , they had done the nromal barrel changes every 10k , so 10x barrels , and towards the end of that 100k , it broke a small pin that holds the bolt stop catch in place , BUT that did not stop the rifle from firing and being able to use .

The new AIs , have the same long thread in , but you just thread them in hand tight and then snug up a small allen head bolt & its done .

RE the blasers , the Aussie Army use the 338LM model , and was out into service with out the usuall trialls , ie emergency issue , word is they have had some trouble ie blow ups ?
