Clean up was a breeze last night...MPro-7
I took my Sport out to the range yesterday and proceeded to put ~450 rounds through it. When I got home I was eager to try out the new bottle of MPro-7 Cleaner I got earlier in the week.
Let me preface this by saying that after my previous range trip (three weeks ago) I cleaned the gun with Hoppes #9 and lubed it with MPC Firepower FP-10 (which was all the rage on the Sig forums back in 2004).
So yesterday when I got home I broke down the rifle and put the disassembled BCG into a small bowl and gave all the parts a thorough spraying with MPro-7. Almost immediately the carbon build up began dissolving into the solution. Good sign.
I let it soak for 20 minutes while I took care of cleaning the lower and upper. When I finally got to the bolt I used a large copper bore brush (one of my .40 cal ones) and gave the bolt tail a light scrub which removed nearly all the carbon build up. I finished with a short buff with a green Scotchbrite pad and just like that the bolt tail was fully cleaned. No muss, no fuss.
Even though the MPro-7 smells like soap rather than the classic gun smell that is Hoppes #9, I'm glad that I didn't purchase that quart bottle of Hoppes and got the MPro-7 instead.
I also used an old tube of Blue Wonder gun cleaner to clean out the bore. But seeing how well the MPro-7 worked I'm planning on buying their Copper solvent to try as well.
