FX Impact adjustable buttstock T-Rex style

Snipex T-Rex style precision stock for FX Impact (or Maverick) with monopod and pouch mount. This stock modification aims to evoke the look of the Ukrainian Snipex T-Rex rifle; by using a pouch to secure the FX Impact at the rear, this feature facilitates final adjustments before firing.

The adjuster requires four M10 nuts and 10,5 cm of shank screw. Two of the nuts are placed on the upper block, and the other two secure the height adjustment rollers with locknuts. Two M5 Allen screws and their nuts are used for the shoulder rest and the support shaft.

When placing the nuts in the H-shaped cavities, test different positions of the upper nut to ensure the thread engages smoothly after passing through the lower nut (there are six positions to test), it is a good idea to secure the position of the upper nuts with a little drop of cyanoacrylate to ensure thread continuity. To place the nuts in the upper circular receptacle, position the nuts on the H-shaped piece and insert it at a 90-degree angle, then rotate it into its final position. If it is difficult to turn, you can apply a small amount of oil to facilitate movement and allow the piece to rotate. On the sphere that allows the lower movement, before releasing it, secure the 10 mm stem with a soft adhesive (such as Loctite). Once inserted, use a lateral motion to release the sphere.

PLA - CF, you can add a soft lower protector (optional) printed in TPU95 with the following ORCA parameters: Wall Loop = 1, Top and Bottom Shell Layers = 0, Gyroid Infill 20%, and glue it with cyanoacrylate. This piece won't make the buttstock any smoother, but it will prevent damage to the PLA-CF edges, which tend to chip when the rifle is supported vertically.

Update: upper axle box reinforcement
