M4 Comando

[BRAD95]

hello and sorry if i have posted in the wrong category i am new to this

I own a JG M4 Commando With folding stock

i have snapped my front sight and only have the metal bottom half which is keeping my handgaurd sturdy

i was wondering how do i fit a new sight and will i be able to have a bigger RIS/RAS than the size of my hand gaurd at the moment?

thank you and i hope it make sense

ps the photos i have attached are what i have and what i would like my gun to look like E.g. shorter barrel/shorter looking barrel / longer RIS/RAS

retractable stock rather than folding and a red dot sight

Daft question but is the front site fixed I.e welded to the barrel etc?

No experience with JG but most other makes allow you to change Barrels/Handguards to any length from very short (3-4") up to M16/AR15 length and beyond with no problems. I have a couple of G & Gs which I have a set of Barrels ranging from 9" up to the standard 12" (or so) and a 16" Bull Barrel yet to be fettled.

Replacing the front sight should be just a case of removing the flash hider, then punching out the two pins that holds the front sight in place, pulling it off and replacing it with a new or secondhand one. Note, that doesn't apply to G&G Combat Machine barrels, as those have moulded flash hiders and front sights and are not replaceable.

As regards the length of handguard, that is usually determined by where the cutouts in the barrel for the front sight retaining pins are situated. However, you can get replacement front sights that are held in place by screw clamps, rather than pins, which means that provided the outer diameter of the barrel doesn't change from where the pin cutouts are, forward towards the flash hider, that you could fit it farther out and therefore fit longer handguards. Alternatively you could buy a different barrel to suit an 11 inch handguard.

Forgot to mention the crappy G & G OEM Barrels LOL They were the first thing I replaced ;-)

If fitting a longer outer Barrel and moving front Sight/Gas Block you will need a longer Gas Tube (which is what I'm still looking for) or make one from a bit of suitable Wire.
