Military Rail Hanguard System |
| The F8Max® is our version of a military style rail-mounting handguard system suitable for the M4 Carbine.
For a nmber of reasons the military M4 rail-mounting handguard system needed some tweaking. It worked, sure, but it left a great deal to be desired. The current system does not free-float the barrel, and when mounted with the sometimes heavy loads of periferal equipment (lasers, night vision, flashlights, etc.) put quite a bit of strain on the barrel. Additionally, even with the double heat shield handguards, the barrel assembly was becoming so hot under full auto fire condistions, that the shooter could barely stand to hold on to the weapon. The heat was becoming so high, that cook-offs were not all that uncommon. The F8Max® eliminates all those problems. [NOTE: The following photos are of the original prototype F8Max®. All picutres show the product in the white before either the Maxhard® treatment or hard anodized finish have been applied. Additionally, these photos show that the picatinny rails are attached via hex-head set screws. This was done simply as a matter of expediance for military testing purposes. The final production models of the F8Max® will have an outer/primary tube made from solid extruded Aluminum, thereby making the picatinny rails an integral part of the primary tube.] |

This picture illustrates the 3 parts that make up the F8Max® handguard.
From left to right:

The inner tube of the F8Max® and it's relationship to the outer/primary tube is the secret to the patent pending heat resistant capabilities of this handguard system. This inner tube not only allows for the free-floating of the barrel assembly (thereby allowing for the attachment of all the external periferals you like regardless of weight without the added stress to the barrel), but also creates a "dead air" space between the liner and the primary tube reducing the transfer of heat the the shooters hands significantly. You can see the center portion of the tube liner is a smaller diameter than both of the ends of the tube. For military and full auto configurations, this "dead air" space will be filled with a high tech heat resistant material similar in nature to heat sheilds found on the space shuttle. |
| This view shows the looks of the primary tube by itself. From the emd you can see the hard points for mounting your picatinny based periferals. Agsain, this shows the tube with the rails attched as separate pieces. In the finished product, this outer tube will be made from an extrusion, making the out tube all one piece. |

So there you have it. The F8Max; strong, heat resistant and ready for action. At the time of publishing this text, a projected suggested retail price has not been established. Projected release date is April 1, 2001.
