Eisenach1 Posted July 10, 2015 Share Posted July 10, 2015 We do Right -Side only Currently. I'd call Crosshill with any issues. Once a Bolt Carrier is Heat Treated, it's a Bear to machine etc. unless you have proper equipment. Crosshill could put it back on the lathe either way Link to comment Share on other sites More sharing options...
wgj3 Posted July 10, 2015 Share Posted July 10, 2015 I asked them about it when I go it and they advised against lightening it which I think is just them being cautious. I feel fairly certain that it could be done safely by someone with the right tools and knowledge. Link to comment Share on other sites More sharing options...
Eisenach1 Posted July 11, 2015 Share Posted July 11, 2015 Gotcha. Yes, it can be done. It perhaps won't be cheap and it might be better to find a new low mass BC and drill and tap it for your side-charge handle instead? Link to comment Share on other sites More sharing options...
Steve RA Posted July 11, 2015 Share Posted July 11, 2015 Out of curiosity, do your side charge handles fit the LAR upper/bolt carrier ??? Might not be a bad idea to have an extra if mine ever should fail. Link to comment Share on other sites More sharing options...
Graham Smith Posted July 11, 2015 Share Posted July 11, 2015 Is anyone using an ambi-side charge upper? What's the advantage / disadvantage? Link to comment Share on other sites More sharing options...
wgj3 Posted July 11, 2015 Share Posted July 11, 2015 I think that most of the ambis allow you to have a handle on either side, but don't necessarily have a handle on both sides. Link to comment Share on other sites More sharing options...
Eisenach1 Posted July 11, 2015 Share Posted July 11, 2015 Our Handles do not fit a Crosshill/LAR. Our Handles screw Straight into the Carrier. Link to comment Share on other sites More sharing options...
Steve RA Posted July 11, 2015 Share Posted July 11, 2015 My LAR handle screws into the carrier also. Link to comment Share on other sites More sharing options...

BitchinCamaro Posted July 12, 2015 Share Posted July 12, 2015 I think the easier question would be "What is the thread pitch on your charging handles?" Link to comment Share on other sites More sharing options...
Steve RA Posted July 12, 2015 Share Posted July 12, 2015 True, I'll take my handle down to the hardware store and check the thread pitch and I'll also check the dia of the shank portion to see if that matches. I like the way the holes are thru the handle on the Eisenach Arms handle, if it'll fit. Link to comment Share on other sites More sharing options...
BitchinCamaro Posted July 12, 2015 Share Posted July 12, 2015 I'll save you the trip to the hardware store, Steve! The LAR/Crosshill is a 10-32 with about .187" of exposed thread . I'm heading out to the range in a bit so I'll get the shank diameter for you. Link to comment Share on other sites More sharing options...
Steve RA Posted July 12, 2015 Share Posted July 12, 2015 OK, thanks. Link to comment Share on other sites More sharing options...
Eisenach1 Posted July 12, 2015 Share Posted July 12, 2015 Our Handles are 1/4 X 28 pitch Class 3, with .24 Dia Link to comment Share on other sites More sharing options...
Steve RA Posted July 12, 2015 Share Posted July 12, 2015 Ok. Won't fit. Still like yours with the hole thru the handle to tighten/loosen. Link to comment Share on other sites More sharing options...
Eisenach1 Posted July 12, 2015 Share Posted July 12, 2015 We have had Zero issues with our handles since having a larger diameter. If a customer ever has an issue with our handles, we will replace it, at no charge every time! Hope to make a video next week showing the strength of our handles vs. other mfg. Stay tuned...

BitchinCamaro Posted July 12, 2015 Share Posted July 12, 2015 (edited) Just for future reference, the original knurled LAR charging handles have the 10-32 thread, ~.25" width at the shank, and weigh .15oz. The Eisenach does look like a nice piece though. Edited July 12, 2015 by BitchinCamaro Link to comment Share on other sites More sharing options...
Steve RA Posted July 12, 2015 Share Posted July 12, 2015 Ok, the unthreaded shank on mine measures right at .250 although it doesn't seem to be perfectly round. Length of the unthreaded shank is .277 and the diameter of the threaded portion is .186 and I don't know the thread pitch. The length of the threaded part is .202 BC, is it 10-32 or 3-32 ???

BitchinCamaro Posted July 12, 2015 Share Posted July 12, 2015 Corrected. 10-32 thread. I've been shooting in the desert all day and my brain is a little sunburnt! Link to comment Share on other sites More sharing options...
fastshooter03 Posted July 12, 2015 Share Posted July 12, 2015 All the thread bolt carriers I have done have been the same as what Young does with 1/4-28 threads. Location of hole in carrier is .250 from end .050 off centerline. Nick Link to comment Share on other sites More sharing options...
jh3g Posted August 14, 2015 Share Posted August 14, 2015 I think that during the off season I'm going to swap in a Gibbz side charging upper onto my 3gun AR. Link to comment Share on other sites More sharing options...
Brian04rs Posted August 14, 2015 Share Posted August 14, 2015 I just completed a build with a joe bobs Spartan non reciprocating side charger (I think same as gibbz) rhino low mass bcg taccom lw buffer and has been working great! way better then a standard upper charging handle in my opinion, and it's nice not having the charging handle coming at your face??
