The ICD AR/MoFo (MOdular FOre-end) Chassis is suitable for use with any Ruger American® Rifle equipped from the factory with AR15/STANAG magazine (fits any and all RA’s feeding from AR mags as original equipment) and can be used with 7.62 x 39 and others that use staggered feed magazines by swapping to AR/STANAG format mags designed for use with X39 cartridges. It can also be used with 450BM Ruger American® Rifles regardless of factory mag style.

Our original Indian Creek Design Ruger American® MoFo (MOdular FOre-end) Chassis was designed from the ground up by Ruger American® (RA) shooters for use in hunting and competition. In this newest incarnation it remains the only 100% American made billet chassis made specifically for the RA versus some rehashed Remington 700® inlet that isn’t ergonomically suitable for use with the tang safety design of the RA line. The MoFo Chassis is the solution to the most common issues facing RA owners who enjoy the phenomenal accuracy and relatively low entry price of the rifle but would like something to address the flexible economy grade factory polymer stock. Whether used for hunting or for ringing steel, punching paper or keeping your area's varmint population under control, ICD has you covered.

Customizing your RA has never been easier! You can outfit your chassis as you see fit, making it mild or wild as it utilizes common AR hardware for the pistol grip and butt-stock. The possibilities are virtually endless, and because we’re blue collar folks like most RA owners are you know we packed it full of value with features others charge premiums for.

The MoFo Chassis comes with the buyer's choice of 4 different Fore-ends:·

Our fore-ends are as follows (you can match these up in the picture-)

Tommy (8.5” long, same exact length as your OEM stock when mounted to the action body of your choice)

Lil John (8” long, or 1/2” shorter than your OEM stock) the lightest of them all. 4 M-Lok slots on sides/bottom and full length RRS Standard ARCA Swiss rail.

Johnny (11 1/2” long, or 3 1/2” longer than your OEM stock) this is our most popular fore-end as it fits on ALL Ruger Americans. 6 M-Lok slots on sides/bottom and full length RRS Standard ARCA Swiss rail.

Big John (15 1/2” long, or 7 1/2” longer than your OEM stock) This is the longest, and will NOT fit on a Ranch model with 16” barrel but will fit on anything over that. With 8 M-Lok slots on sides/bottom and a 13 1/2” RRS Standard ARCA Swiss rail.

All MoFo Chassis are finished in Black Type III Hard Coat anodizing. Hard Coat Ano is an enduring finish that will stand up to the rigors of field use and it protects the billet aluminum more than any other treatment. And even though they look as good as they shoot, you can always paint or Cerakote right over the anodizing if you want a different look than basic black.

Chassis Details

The ICD AR/MoFo Chassis comes with new 1/4 - 28 x 1" action screws with bushings, a 1/4-20 x 3/4" grip screw, action saddles, 1/4-20 x 3/8" fore-arm mount bolt, and a front sling swivel post on the Tommy fore-end. On the AR/MoFo you will re-use your factory AR15 mag latch or use any milspec or other aftermarket latch that is NOT EXTENDED (no one has fingers long enough to reach even an extended latch).

We suggest only using Carbine style buttstocks on your MoFo. The MoFo accepts AR collapsible commercial and MilSpec buffer tubes, our STFU side folder, and many other items. We do not recommend any fixed/Rifle pattern stocks due to the tang safety design of the RA and how that interferes with the shooters grip hand. You CAN run a Rifle stock, but we caution you to look at the application more closely first. The MoFo accepts all flat top AR pistol grips (without beavertail) and while some soft beavertail models may fit depending on the style/manufacturer, we do not recommend their use as safety access may be hampered. Every good grip with a beavertail has a flat top version of it too- Seek out the right stuff! Max Barrel profile is a straight taper 1.4" O.D. (yes, larger than any RA action can accept, so it can fit any barrel you can fit to the RA action.
