m16 full lenght ris rail sleeve

[Jonmarshall]

Hi

I need to know if I could find an RIS sleeve rail that could do the entire lenght of my spr mod 1 + m4 body. Im going to receive my spr mod 1 front end within the next few days and im looking forward to this kind of sleeve to make my spr mod 1 an alternative aluminum baseball bat. No really I just want it to be more solid as I own a plastic body (i know its bad)!

This kind of sleeve would make my spr mod 1 look more like the mod 0. Maybe Nitro, PM or Actron make it but im tired to search it over the internet as I know some of you guys own it for sure and could give me some advice on wich one to choose!

Thanks
Jon
