I recently purchased a SKU#811310 - Model M&P10 Compliant without the flash hider, Threading a barrel for a compensator or in this case a flash hider is likely a relatively simple operation that can be accomplished by any competent machinist( I say with high hopes) any recommendations from someone that found another way or that has had or seen this dealt with? Are the complications I haven't foreseen with the M&P 10? Cost even? I don't live in a overbearing Compliant area, so no concerns there.
