I'm trying to finalize a new-to-me upper that I bought to complete a lower that I built recently. I currently have a KAC M4 RAS on there, but the truth is I like to grip the forend a fair amount further out than that platform allows. Problem is, I got the upper from Spikes pre-configured to be compliant in the ban state that I am unfortunate enough to live in, meaning I can't (at least in any way that I know) remove the compliant break to get everything else off. I'd love to add a FF rail to the rifle, but it seems that in order to do so I will have to lop off the FSP. From a technical standpoint, I don't have a problem with this, and I would already have to cut off the current D ring assembly et al, so I'm not averse to that kind of work. On the other hand, I'm interested as to whether there exists a rail platform with a relief for a FSP that is around 12" that I could mount to this rifle without removing everything (or anything). I feel like I have looked everywhere, but perhaps someone on here knows something that I have overlooked.
Thanks for all your help! |

The Centurion C-4 Carbine Cutout will get you to around 9" while keeping the FSP...
Or you can cut the FSP down along with the D-ring and handguard cap and use the Centurion C-4 12" that uses your stock barrel nut. I use the Mid-Cutout on one of my rifles and these things lock up very solid. |

Just cut off the delta pack (or if you have the tools/know-how, take off the barrel and remove the delta pack) and install a Centurion Arms handguard on the standard barrel nut. C-4 carbine cut-out rail C-4 12" rail I would also consider Weapon Outfitters for the CA stuff (free shipping on orders over $100 and an Arfcom discount code). |

Here is a video from Samson that shows how to add a ff tube to a rifle with a perm attached muzzle device. It is the last 5 minutes of the video, and he leaves out a couple things, but you can get the gist of how it is done.
http://youtu.be/XwIBJQo4qeA I imagine this will work for just about any ff tube. |

Only applies to FF tubes that use the standard barrel nut. Many designs use different barrel nuts. ~Augee |
