See the link for parts breakdown:<br /><br />http://www.gunpartscorp.com/Manufacturers/USMilitary-33541/Rifles-42386/M1Garand-40101/PartsList-37106.htm<br /><br />Ideas to fix: a. replace complete upper handguard.<br /><br /> b. build up the wood tang using plastic wood and sand down to just barely fit in the ferrule groove.<br /><br /> c.If it's loose on the front end of the foregrip, the front ferrule or the handguard spacer, front. Needs to be worked on, there are 4 tabs (2 front and 2 rear) that bend around to hold the 3 parts together. The handguard spacer, front should be tight on the wood handguard (on the rear tabs), and just a little bit of play on the front 2 tabs (that bend around the front ferrule. (this allows for heat expansion, so the forestock doesn't get damaged when the barrel is hot. If the forestock is nice and tight in both ferrules, but still wiggles. try replacing the Gas Cylinder Lock (numrich pt no44), the lock threads that screw into the threads on the barrel were not all cut the same, the starting point of the threads differ, and you can get a tighter fit between the gas cylinder assy, and the forestock (but still leaving a litte wiggle room for barrel expansion).<br /><br />Barrel Crown Ding. Either live with it, till the barrel wears out, recrown, or replace the barrel. NOTE: I've seen some comments on .308 Garands, where a new .308 full length barrel can be put on that is the same length as the .30-06 barrel, but the stock, rear handguard, and oprod would have to be replaced with full lenth parts. <br /><br /> Point of history, I've seen comments where the rechambering of the barrel was done by trimming 1/2in off the threads, recutting the threads and putting the barrel on and chambering for .308 NATO. which is why the oprod, stock, are rear handguard had to be modified.<br /><br />Just some ideas on your problem, I'm not a gunsmith, but I've had a full size M-1 since 1989.<br /><br />RHBc-90https://www.blogger.com/profile/07248346499641654640noreply@blogger.comtag:blogger.com,1999:blog-3274583756441452923.post-47235170566504477972016-09-29T17:00:13.973-04:002016-09-29T17:00:13.973-04:00When in doubt, I'd go to Fulton.When in doubt, I'd go to Fulton.Old NFOhttps://www.blogger.com/profile/16404197287935017147noreply@blogger.comtag:blogger.com,1999:blog-3274583756441452923.post-11500272838939181202016-09-29T08:06:26.734-04:002016-09-29T08:06:26.734-04:00Also get a final call about a chamber insert, if p...Also get a final call about a chamber insert, if present...
