I am currently doing a project for my M11/9.

I am converting it to a TASK style slow-fire which utilizes a AR stock ( either the A1, A2 or CAR stocks ).

I am going with the CAR stock for now.

I picked me up one at Tapco that works just fine.  

Only problem is I need two more of those threaded rings that move up and down the threaded part of the stock "tube".

What is this part called?  Where could I get more ?

I am not talking about the CAR spacer which looks like a inverted teardrop.  The part I am interested in is the threaded ring.

I saw one website refer to it as a indexing spacer.  I am not sure if that is the correct name or not....

Any help would be greatly appreciated =)

Thanks, USMC_LB

I believe the part you're looking for is the Telestock Locking Nut. Bushmaster sells it for $6.95 (part#5310-917-1153).

Thats it, exactly !

Thanks so much, BlueMonkey[8D]
