Yep, it fits perfectly. (I took a gamble and ordered one). Replaced the Surefire forend light and the pistol grip stock with the M2 and a factory straight stock. Now my "tactical" M1 is NY friendly. sigh. Anyway, two more questions. The surefire forend had a aluminum sleeve on the receiver end, that seems act as a spacer between the forend and the magazine tube. Its about 2.5" long and is split on the barrel side. It seems to have no place to go with the M2 forend. Just wanted to confirm that it's not needed. Also, there were three rings on the tube nut side, that when I install on the new forend, seems to prevent the nut from locking down (that ratcheting effect) at the bottom of its travel. Seems like they aren't necessary, but again, just wanted to check. All is tight and pretty as-is, so....
Thanks all
