The Grey Birch Solutions LDR Fusion Barreled Receiver System has the same footprint as the legendary 10/22™, but that is where the similarities end.

The Fusion Receiver System (FRS) is a 10/22® compatible threaded barrel system that offers increased stability for consistent and accurate shooting. Threading the barrel and receiver into a single unit overcomes a significant flaw found in most semi auto rimfire rifles. The barrel is typically levered in place with either a v-block or grub screw. The disadvantage of using a v-block to attach the barrel to the receiver is a loss of elevation or windage due to tolerance differences between the barrel and receiver, allowing the barrel to shift. This is what is known as barrel droop. The result of barrel droop is a loss of accuracy and consistency of accuracy. The Grey Birch Fusion Receiver System (FRS) solves this problem, ensures perfect alignment between the receiver and barrel, allowing the shooter to achieve bolt action like accuracy consistently.

The LDR, or Long Distance Ready, has an integrated 20 MOA Picatinny rail machined into the top of the receiver ready to mount the optic of your choosing.

The 16.1” or 12.5" barrel has a carbon fiber wrap over a 416 stainless steel liner. The muzzle is threaded ½-28.

The receiver itself comes stripped with only the barreled attached and is made from 6061 aluminum with a hard clear anodized finish.

The Fusion System is assembled with job specific tools to ensure proper fitment and to ensure the correct headspace. Trying to remove the barrel will likely result in damage to the components and will void warranty on your Fusion.

The Fusion Receiver System is compatible with most 10/22® accessories. Some minimal modification to the stock may be required in some cases.
