  1. Red locktight?… why??? What if you wanted to switch to a piston or something happened that required you to get it off? Drilling out the bolt holes 1/16 into the barrel would give you a mechanical advantage rather than a chemical.

    To each his own, just never heard of that before.

  2. so how do the bolts hold up to being cut so thin to fit the 45 cartage. I know the 7.62×39 bolts has some issues with breaking from being weakened by using a AR bolt thinned out to fit the bigger case.

  3. Please excuse me for keeping on bugging you..I'm looking for a 6pos.rear. I've got the stiff springs. For the buffer.do I need to change my tube.? For a good. Quality 1' or can I keep the. Buffer that came on my bush var.lower. yes it is a solid..looking for for a good quality 6pos. Do I need to change my tube?' 4 that.?' Im just asking for your opinion…I've got a few in mind..I'm looking for something with a 6pos.with a good cheek weld…please give me your opinion be4 I spend.$$$''yes thank you if you reply.to this.

  4. Wow thanks for quick response. Did you buy it at bullseye in north branch? I read somewhere that they're the exclusive dealer. I just live down in faribault about 100 miles south of where they're made.

  5. I think they are really nice. When I was in the shop doing the transfer on it, The owner used it as an example of excellent fit and finish to another customer. As good as a Mega imo.

  6. @clayton758 Use blue if you want to be able to get it back apart easier someday. I'm not planning on stripping it down any time soon and the red loctite is higher temp resistant. Just the choice I made….to each their own 🙂

    The only draw back is the price of ammo. I can see you using the bolt with the larger face and a smaller caliber barrel and come up with something unique. something in the 6-6.5mm range would be cool.
