The whole front end?
I'm thinking either of these three:
XM110 front end: http://www.landwarriorairsoft.com/cgi-bin/...23aGP841#aGP841
SAM-R front end: http://www.landwarriorairsoft.com/cgi-bin/...23aGP841#aGP841
M4 FF RAS (long): http://www.fire-support.co.uk/product/gp-m4a1-ras-long-kit
I prefer the XM110 one, but it depends on the markings on the side of the rail, and it is £180..
Probably not gonna get the SAM-R one, it's £170 and the only difference to what I already have is the handguard and front sight - the barrels the same.
The M4 FF RAS has the same rail as the SAM-R, but a different barrel, and I'm undecided on whether I like it. It seems the most sensible option as it's cheapest..
Anyone know what's written on the side of any of these rails? It's important to me
Also, Ed, are/have you changing/changed the pistol grip?
