308 Barrel Nut Shim

OK so you're playing with your new build and son-of-a-bee-itch. The hand guard don't fit, the barrel nut, she ain't in the right position. That's OK, these little guys will help more things forward a bit properly without the need to Macgyver a solution. Similarly, if you can't get your gas tube through the barrel nut without uncomfortably exceeding the torque specs, try inserting one or more of these until the alignment gets closer to perfect.

If you're trying to time a barrel nut, we did the math based on a standard 18 tooth per inch barrel nut. These are estimates only, real world results may vary depending on planetary alignment:

• 0.3mm shim makes approx a 1/5th of a rotation
• 0.5mm shim makes approx 1/3 a rotation
• 0.9mm shim makes approx 1/2 a rotation
• 1.95mm shim makes approx 1 and a 1/3 rotation
