Linemount M1 Carbine Bolt Disassembly Tool/Reassembly Tool

This tool works great. Make sure you watch a few Youtube videos before using. I took apart a bolt, manufactured in 1945 and assembled into a Universal rifle made in 1966. I found that my extractor spring plunger was broken. I quickly order from Numrich Parts and it is all fixed. What a very useful tool.

Had a carbine bolt that needed reassembly. If you have ever worked on one the little extractor plunger is a huge PIA to install without it flying into the nether regions of your work space. This tool made quick work of holding it all together, allowing you to fit parts if need be. You literally can't assemble a carbine bolt without one. Solid buy!!

Updated review: Seller sent me an immediate replacement without me even asking for it. That alone gets points for customer service. Was able to get it to work properly the second time around. I do however, recommend that you find some detailed videos on YouTube to show you how to use it. The video link provided by the seller is garbage. No good closeup and the guy in the video is holding a black tool against a dark background, so you can't see anything! There are MUCH better videos out there and I highly recommend that you look for them. I'm going to take off 1 star for the video quality but I do thank you for the replacement tool.

Works better than I was expecting and is well made. Must have tool if you own an M1 Carbine!

There are ways to disassemble you M1 carbine bolt without this tool, but you are risking your bolt and your sanity if you do. This makes it sooo much faster and easier. Comes with instruction, or you can check out some YouTube videos.

I Could Not Have Disassembled/Assembled The Bolt Without This Tool.

Honestly, I wasn't too impressed when first using this, BUT, my opinion has changed. I snapped the lower finger off for the extractor installation side (looks like 2 prongs sticking out) I thought it was a cheap tool, but actual GI ones go for over twice what this cost, So I ordered another, meanwhile comparing prices on another E commerce site, I stumbled across actual GI replacement heads for the extractor removal part, I ordered 2 since I was buying a second tool. My replacement arrived broken already, Amazon immediately replaced it. My New tool arrived and got the job done. Meanwhile in the middle of working on 5 carbines, my replacement head arrived, I installed and first use, it broke. So my thinking was Original GI has to be better, it is, but by a very small margin. So my opinion of what I thought was a cheap replacement for a GI tool, went up to believing it's 99% as good as the GI if you do your part. What do I mean by do your part?, I imagine seasoned users already know, But when screwing the bolt forward it's critical to watch the extractor pin and make sure it's moving inward and seating, if you keep applying pressure and the pin gets hung up like I did without realizing, SNAP!!!, You need a New tool or replacement head. - For those unsure how to use this tool, YouTube is your friend. - I knew going in the flat side of the extractor pin must face towards the bottom of the bolt, that pin is tiny, so check it and recheck then make sure the split prong actually grabs the pin, then make sure as you turn, that pin is seating into it's hole, if not, back off, wiggle the pin a little and keep trying, a little grease or even oil on that extractor spring helps hold that pin in place instead of falling out and getting lost easily. I hope that description helps somebody going forward.

The price is very fair especially when you look at the time savings and not screwing things up. Great purchase!
