[QUOTE="Of001, post: 2438850, member: 116075"] I've got the same rifle, MTR and I was just using a snake and just put the rifle vertical and no mess but I dropped it once. :( I couldn't find a bore guide so I made one. I took a thin peice of PVC, semi rigid stuff for hydroponics. The stuff about twice as thick as a straw and just bigger than 17. I put 2 cold sleeves (2 pieces of airline I got from a hose shop, free scrap) to about 0.5in from each other, heated with a heat gun and made a bulge. Then I took a peice of heat shrink and used hot water to size it over a spent case and over the peice of PVC with a heat gun. The water kept it from rippling and sticking to the case. I've got the bulge just a few mm from the heat shrink, helps to center end of the thing and stopped flex at the end, and I punched a wine corke and that holds where the bolt handle goes, the heat shrink step up acts as a plug and the jag fits, just, through the heat shrink, which goes into the bore by about 2cm. And I use a qtip to get the first 0.25in when using solvent Looks like **** but works. I've used it 15 times, I had to redo the heat shrink once but I just jammed it in there like I didn't care. Oops. I dry snake it every 50. Solvent on a snake every 100, and 10min solvent soak every 200 with a rod/loop jag. The MTR chamber is uber tight so I feel like a surgeon some times, I had to buff the solid jag down a half hair. My friend heat shinked the PVC to a drilled spent case but the heat shrink didn't work the first time and it got stuck because he didn't downsize the jag enough. [/QUOTE]
