M4 Sentry Ris removal

[CaptainPriceSAS]

Probably a stupid question but im wanting to replace the standard ris front with a magpul moe, but cant figure out how to remove the gas block/iron sights. When i try to take them off they get caught on a silver bit at the end of the barrel. Im not very techie with guns and have never messed with them before so i have no real idea on how to go around taking off the rail.

Thanks.

i think that u need to remove the flash hider first and thake that silver ring off the barrel..

Re: M4 Sentry Ris removal

Start at the front, is the flash hider and spacer removed? Once thats done should just be a case of knocking out the 2 pins in the front sight and possibly a grub screw underneith it.

Then the ris is just a case of un-doing the 6 bolts near the body, then once the ris is off there will be a barrel nut and ur either need the correct tool to remove it or a pipe wrench or something that u can get round it to undo it.

Gonna pm u aswell with possibly a solution to an easier way

Re: M4 Sentry Ris removal

once you unscrew the flashhider off, it should just slide over the threaded end of the barrel
