After cleaning all the cosmoline off my "new" USGI Bolt Tool, I put it to work on my NPM Bavarian carbine. I followed along with the Bolt Disassembly video listed on this forum. It was a great help. One observation, the disassembly and assembly of the carbine bolt without that tool has got to be darn near impossible. I'm sure folks have done it, but it would be very frustrating for me. The disassembly was very straight forward. I placed all the parts in a pan of Hoppe's Bore Cleaner and let them soak overnight. When I put the parts into the Hoppe's last evening, the liquid was an light amber color. This morning it was black! I guess it needed cleaning. I then scrubbed all the parts with a toothbrush. Next, I cleaned all the orafice's in the bolt with Q-Tips and pipe cleaners. Lots of black residue came out of the openings; I got them all clean. Following the video closely, I reassembled the bolt as shown. Everything went back into place just as described.  While everything was apart, I closely examined the NPM bolt (N14) for burrs and cracks. Using a small magnifying glass, I saw nothing unusual. My Rock-Ola's bolt is next. ------------- Semper Fi, Bruce |

| For the datasheet, I like to use the bolt tool, but leave the bolt in the tool just to pull out the firing pin to look at the marking. Then, just slip it back in and no fiddling about trying to get it back together. With a loupe or magnifying glass, collector's can make out all of the other parts. |

It could be done, Though I would advise against it http://www.uscarbinecal30.com/forum/bolt-disassembly-assembly-without-bolt-tool_topic1280.html" rel="nofollow - http://www.uscarbinecal30.com/forum/bolt-disassembly-assembly-without-bolt-tool_topic1280.html +1 on what M1a1 said if just looking for marks. If taking all the way down to clean pay careful attention to orientating the plunger correctly. I sometimes use a small flat blade screwdriver to help correct orientation if it rotates while assembling. After back together manipulate the extractor to make sure it is locked on the plunger or it may come out in use. Another tip would be to use the tool inside a 1 gallon zip lock bag or other suitable plastic bag in case parts want to learn to fly.

Thanks for the tips gentlemen. I like using the bolt tool inside a ziploc bag to avoid losing any parts. My tear down of the NPM bolt was for cleaning purposes; that's why I did a complete disassembly. I did use a steel pick to rotate the extractor plunger into the proper orientation. ------------- Semper Fi, Bruce |

| Anybody know if it might be easier to "manually" take apart a bolt if it has a type 1 plunger? |

| The obvious reason they changed the design was that the extractor was prone to popping-out on it’s own. The M14 uses the button-nose plunger and the extractor can be pushed out over the plunger. There is a lot more room to work with in the larger extractors like the M14. I would think the T1 extractor could be punched-out much like an M14. |

Before disassembling the bolt, I like to submerge it in an olive jar filed with Hoppe's # 9 and adjatate with an electric tooth brush for a few minutes. ------------- Charles Co B 1st Batl.115 Inf. Reg. 29th. Divi. 4.2 Heavy Mortar Co Retired Life member NRA |

| For bolt disassembly, there's nothing like the bolt tool. Occasionally find them listed on the web for around $30, but those days might be over. GI ones are probably best but the non GI ones work just as well. One suggestion if going the bolt tool route...get an extra pawl or two. I'm on my second one, but I think I've got the hang of it now. |
