I'm thinking about fire lapping my new Varminter (have not fired it yet) but would appreciate any feedback on this.
I'd plan on buying the kit from Nico and in order to prevent grit from the lapping compound getting into the bolt/carrier and receiver area I think all I'd need to do is remove the gas tube.
I have not taken this part of the Varminter apart before but it looks like I need only push out the pin, push the tube towards the receiver until it pops out, then pull it out of the receiver. Is this right?
Lastly, if this is doable, what precaution if any need I take to protect myself for the blast coming out of the gas tube port?
