Dippin Dave Posted February 14, 2021 Report Share Posted February 14, 2021 Trying to find out what kind of 308 style lower i got in a parts lot with bunch loose ar parts including a 308 style 80% lower. But after milling it out and spraying it with alumihyde i realized a regular bolt catch pin system wasnt gonna work. There and extra cut out tab on magwell side of the bolt catch slot with a threaded hole through to the magwell. I havent ever seen any other lowers with this design and means of attaching bolt catch. Hopefully the following pics will help someone on here to help me. I dont have any idea of maker and can find nothing anywhere online about this design. Thanks.

Dippin Dave Posted February 15, 2021 Author Report Share Posted February 15, 2021 Ok since the 308 crowd is stumped. What are opinions on having someone that welds aluminum just fill in void solid then drilling for a regular type pin or threaded pin?

Ran into something like that on a Fulton Armory 308 build I did a few years back for a brother-in-law, just took me a while to remember where I saw it.

Dippin Dave Posted February 16, 2021 Author Report Share Posted February 16, 2021 Thank you so much now i got something to work with. Im wanting to build a 243 or 7mm-08 as a deer rifle.

It's just a .308 Win case necked down to 6mm. 6mm projectiles are amazing. What twist rate is the barrel that you have? Quote Link to comment Share on other sites More sharing options...

That's about the limit for a 1:10" twist on a .243. I've got a Rem bolt gun with a 1:9 1/8" twist, that I'm still working on loads for, but I'm hoping that twist let's me shoot the Hornady 108gr ELD-Ms well, and the 103gr ELD-X even better. Hornady makes a 90gr GMX that would probably kick ass in that barrel of yours. Quote Link to comment Share on other sites More sharing options...

If it goes BANG! when you pull the trigger - we love it here... Thought you were gonna "get out some weird shiit" talking about that .243, didn't ya?...

ARTrooper Posted February 16, 2021 Report Share Posted February 16, 2021 Probably almost a fourth of the deer I have taken have been with a .243 win bolt gun. the cartridge can take deer ethically out to 300 yards no problem with the energy, velocity, and flat shooting several good high bc ballistic tip bullets have. Of coarse the smaller and lighter bullets with lower sectional densities compared to .308 and many other hunting rounds means you will have to be more accurate with your shot placement. But I would never fault anyone wanting to use a .243 for whitetails Quote Link to comment Share on other sites More sharing options...
