    Bolt action cam surface wear?

    So .005" of wear would be too much? How long/howa many rounds does that amount of wear normally take to develop?

    Bolt action cam surface wear?

    I have a Howa 1500 HCR in .308, which currently has about 600 rounds through it. Being as this is my first "precision rifle" i have never shot this many rounds through a bolt action before. Earlier, i had the rifle disassembled to adjust the trigger, and noticed some "strange" wear on the bolt...

    Gunsmithing Muzzle brake torque/crushing a rifles crown?

    I know you 'should' use a torque wrench, but i dont have one and im already over budget for this build. The system that PA uses (if done with the right washer) should get you aligned within the torque spec. If you do the calculations for the effective area and clamping force, you would have to...

    Gunsmithing Muzzle brake torque/crushing a rifles crown?

    I am working on installing a muzzle brake (Precision armament m4-72) on my heavy barrel 308. I chose to get the PA accu-washer shim set to time the brake. I chose the one I thought was correct, but when tightening down the brake, I could not get it to index properly. Didn't use a torque wrench...

    Gunsmithing Securing buffer tube to Howa HCR chassis

    I dont really want to add any more weight (already going to be probably 15lbs with optics and accessories) by putting lead in the buffer tube. Did/do you have the Howa HCR with the Accurate-Mag chassis? Because they come with a Luth-AR stock, which has a set screw to tighten down so it doesnt...

    Gunsmithing Securing buffer tube to Howa HCR chassis

    Thanks. I already own a different Howa rifle and love it. I hope to use this one for some medium range deer hunting and casual range time.

    Gunsmithing Securing buffer tube to Howa HCR chassis

    Well i guess i missed that during disassembly. I cant look now because the chassis is out for cerakoting. Thanks for the heads up. The set screw on mine must not have been tight from the factory because the buffer tube screwed out easily after i loosened the castle nut. If it had been tight, i...

    Gunsmithing Securing buffer tube to Howa HCR chassis

    There is no set screw for the buffer tube. I wondered that too, as AR backplates have that lug to match the keyway on the buffer tube. But this chassis does not have one.

    Gunsmithing Securing buffer tube to Howa HCR chassis

    Okay, so do you put it on the buffer tube, the castle nut, or both? I doubt i would ever take it off again (unless it somehow got damaged) but i do want to be able to remove it if i have to.

    Gunsmithing Securing buffer tube to Howa HCR chassis

    Hello all, Im new here, and this is my first post. I have a quick question about buffer tube/stock mounting on aluminum chassis rifles. I recently acquired my first precision rifle, a Howa HCR (got a killer deal btw) and i decided to have the chassis cerakoted. Not wanting to shell out the...
