The MBA-1 Buttstock is a Rifle Buttstock and requires the use of an A2 style buffer tube. This is a “fixed” buttstock. The A2 Rifle buffer tube can be distinguished from carbine buffer tubes by it’s shape, the A2 Rifle buffer tube is completely round in shape while the carbine buffer tubes have a rectangular appendage to the tube that encloses six adjustment position holes. An A2 Rifle buffer tube has no length-of-pull adjustability and is substantially longer than a carbine buffer tube.
