I just put together my first A1 upper with triangular handguards. The triangular handguard front piece is loose and can slide forward 1/4" and allows looseness in the handguards at the front. The rear of the guards are in position around the barrel nut and are secure. What did I do wrong? is there some kind of spacer that is supposed to go between the front sight and the triangular handguard retainer? It is a Colt M16 barrel and barrel nut and mil-surplus handguards so I thought everything would fit......... Any/all help is appreciated! Jeff |
Yes, that is a problem. Its normal for the front retainer to rotate in place, but sliding up and down the barrel is not. There is a slight step in the barrel that keeps it in place. Unfortunately you'll have to remove the front sight base to install a new one.

It slides fore and aft about 1/4" without the handguards installed. Is that not OK? Thanks, Jeff |

OK, here is the back end by the delta ring and the front end at the front sight. The front sight came pre-assembled on the barrel from Sarco but that doesn't mean anything. I have never had really good luck with them and it wouldn't surprise me if it was installed in the wrong place...... http://i150.photobucket.com/albums/s97/Abendshien/IMG_9263.jpg http://i150.photobucket.com/albums/s97/Abendshien/IMG_9260.jpg Thanks again for everyone's help, this thing is driving me nuts!

Dang! And I thought this was going to be easy! Is there any way to see if the gas hole lines up from the barrel to the sight? Thanks gain, Jeff |
Oh yeah.........that ain't right. The front sight base should be ALL the way back to the step. But even then, looking at the pic, that retainer looks funny. The retainer should NOT move back beyond the step. It should get "pinched" between the front sight tower and the step. See if Sarco will fix it. cause it is not right.
