wetncold Posted May 2, 2015 Report Share Posted May 2, 2015 A clamshell for our man sized uppers. Seems everone makes them for the boy guns but not for our man guns. What's up with that? Quote Link to comment Share on other sites More sharing options...
survivalshop Posted May 2, 2015 Report Share Posted May 2, 2015 None that I have seen. Probably because there are so many different configurations of the 308 AR , unlike the MilSpec Ar 15/16/M4 Receivers. Quote Link to comment Share on other sites More sharing options...
wetncold Posted May 2, 2015 Author Report Share Posted May 2, 2015 Yeah. I have one for my boy gun, but I don't want to ruin it by using it on the man gun. Thanks for the reply. Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted May 4, 2015 Report Share Posted May 4, 2015 I have one of the internal vise blocks. It seems better to me conceptually Quote Link to comment Share on other sites More sharing options...
AngelDeVille Posted May 4, 2015 Report Share Posted May 4, 2015 I have the one that mounts top and bottom and it works just fine, but it only works for flat tops. If i was building a lot of em, or had a carry handle, I'd but that big metal shillelagh looking SOB. The clamshell is fine for the toy guns.

Rsquared Posted May 5, 2015 Report Share Posted May 5, 2015 I got a set from Armalite years ago. I don't think they still sell them. Quote Link to comment Share on other sites More sharing options...

I think I prefer aluminum for barrel blocks but these are ok, I won't replace them anytime soon. Quote Link to comment Share on other sites More sharing options...
wetncold Posted May 6, 2015 Author Report Share Posted May 6, 2015 I've got a set of those, but I am concerned about the upper slipping out when removing/installing a barrel nut. Or a flash hide. Quote Link to comment Share on other sites More sharing options...

Barrel nut isn't a problem, but I would use barrel blocks for the flash hider. Just take off your gas tube if you don't have space for the blocks. I think I paid $9 shipped off ebay from that company. Quote Link to comment Share on other sites More sharing options...

BIGBREW Posted February 2, 2017 Report Share Posted February 2, 2017 My buddy works on 3D printers. I asked him about making a clam shell for me. His company sort of frowns on working on weapons. Damn it! Quote Link to comment Share on other sites More sharing options...

The thing is , the Barrel Vice Blocks were first used in the TM for Barrel install & removal , then they were tweaking Upper Receivers using them & changed it to the Clam Shell or Receiver Block , so whats the difference between using a Barrel Vice Block set & this "Action Bar "? Answer ---- Nothing , you can still Tweak an Upper Receiver . Don't say it can't be done ! Just think for a moment on what you are tightening & into what .

Robocop1051 Posted February 4, 2017 Report Share Posted February 4, 2017 Lol, I still use a clam shell for forged AR15's and a vice block for everything else. Quote Link to comment Share on other sites More sharing options...
