Details:

If you’re a fan of the personal defense or close quarters CQB stock and you need an AR-15 Fixed Stock, Strike Industries has heard your cries. The Modular Fixed Stock brings options for versatility and adjustability to the table along with the solid fitment, ergonomics, and hardiness of a fixed stock.

Fixed Stock, Custom Pull Length

The Strike Industries Fixed Stock accepts standard carbine length receiver extensions. When you need an AR fixed stock for an existing weapon, it’s no problem to fit an SI MFS. All you need to do is choose your desired length, install the correct spacing shims and you will have a custom length of pull and an AR-15 Fixed Stock that holds rock solid even under extreme operating conditions. As packaged the MFS is easy to customize in ¾-inch increments from 12 inches to 14.25 inches length of pull.

Polymer Construction with the Security of Steel

The Strike Industries Modular Fixed Stock features the light weight of a polymer AR Fixed stock with the security or quality steel mounting hardware. Strike delivers exactly what you need. Fit, feel, and reliability without compromise.

Field Ready Design

The field ready design of the Strike Industries Modular Fixed Stock requires no additional sling mounting hardware. It features an integrated HK hook Attachment and sling loop. Since you’re working with a solid stock you won’t have to quiet odd rattles when you’re on the move and there’s no worry about catching a latch and pulling up at the wrong length. Simply mount the SI MFS up at your desired length, clip on your favorite sling and you’re mobile, ready for whatever the next maneuver brings.

Installation:

  1. Slide the front piece onto the carbine-length buffer tube until it touches the castle nut
  2. Install the buffer tube adapter on the first slot of the buffer tube
  3. Add adjustment shims if needed
  4. Install the Modular Fixed Stock onto the buffer tube
  5. Remove the rubber butt pad
  6. Use the adapter screw to secure the stock

  • Strike Industries Modular AR Fixed Stock and Extended Butt Pad

    Posted by Donald Howard on 28th Dec 2020

    First time ordering from Wing Tactical and I'm very pleased with the entire experience. I love my new Strike Industries Modular AR Fixed Stock. It was easy to install on my mil-spec carbine buffer tube. Fit of the spacers is very snug which is good. Stock is now set to my LOP and almost perfect. The stock also looks great! My only complaint is that the base of the optional extended butt pad is warped and leaves a gap at the top when you install the bottom screw. The screw is not over tightened. Tightening the screw to where it should be pulls on the bottom of the base and puts too much pressure on the small clip that secures the base to the top of the stock. I'm afraid the clip might snap at some time. I tried loosening the screw to relieve pressure on the clip but that leaves a gap in the bottom and the entire butt bad wiggles. This is no fault of Wing Tactical. May have been just a bad run by Strike Industries. I will leave the extended butt pad off and probably order another one. With the extended butt pad installed, my LOP would have beed perfect. The stock gets 5 stars though, and so does Wing Tactical! They shipped everything well packaged and delivery was right on time. Will definitely shop here again!
