    Would a sheared barrel index pin bugger up the hole in the barrel extension?

    Long story short on my ar15, somehow after torquing my barrel nut to 80ft-lbs (at 90* to the crowfoot wrench) to get the screw holes lined up the index pin on my barrel began to shear/distort enough that the barrel rotated in the upper receiver and prevented the bolt from closing (bolt lugs hit...

    Cabine buffer & Spacer vs Rifle buffer...

    So I've been planning on switching to a PRS stock, and thus need a rifle buffer/tube. I already have a Spikes ST-T2 buffer that I really like, and found out RRA makes a spacer to use a carbine buffer/spring in a rifle buffer tube so my question is would it be better to use a ST-T2 & that spacer...

    Clamp on vs Set screw gas blocks...

    So I planned on using a 15" PXT FFSSR handguard but it doesn't appear my YHM clamp on gas block is going to fit underneath it using my awesome picture measurement skills. So, my real question is there really a measurable accuracy difference between a clamp on and a set screw style gas block? My...

    NM/RRA Free Float Barrel Sleeve?

    Anyone have any experience with the various FF barrel sleeves out there for AR15s? I really like the look of my FDE MOE handguard but I recently switched out my cheap skinny FN barrel for the 18" SPR Match Rainier Arms barrel and would like to get the most out of it that I can with a FF hand...

    Gunsmithing Cleaning a old barrel with SS Rod, Vinger, and electricity...

    Just wondering if anyone has any experience with cleaning an old C&R barrel using this method? Making the Surplus: Homade Electronic Bore Cleaner Basically stick a SS rod through the bore, use rubber washers to create a water tight seal while not letting the rod ground out with the bore, fill...

    Gunsmithing Is Silver Solder good enough for a Mosin bolt handle?

    I've never silver soldered anything before, and since boltman has like a 3 month wait I was wondering would it be possible to silver solder the bolt handle from Rock Solid Industries onto a mosin nagant bolt body? I was thinking maybe I'd drill & tap a spot on the bolt body and drill the bolt...

    Gunsmithing How hard is it to modify a rimmed bolt to accept a rimless cartridge?

    Just wondering if anyone has ever done it or theoretically how hard would it be to modify a bolt (91/30 for this example) for a rimmed cartridge to use a rimless cartridge? Would the bolt be the least of your worries, or the hardest part?

    Any decent barrels in stock?

    Not really happy with what I'm getting now out of my light profile run of the mill barrel, anyone know of any decent 1:8 or 1:7 .223 ar15 barrels in stock anywhere? So far the best luck I've seen is with fulton armory, looking for a ~20" HBAR or other heavy contour in .223 wylde in the $300...

    Gunsmithing PTG/M5 Iinlet in a B&C A5

    Just wondering if anyone has done the inletting for the PTG bottom metal (M5 inlet) on a B&C A5 stock, and if so did you have to remove material for the back portion to fit under the trigger finger? Reason I ask is because due to the depth of that back spot it seems like it would suck doing that...

    Gunsmithing Clear "lacquer" over adjustment screw on X-Mark pro?

    Went to adjust my x-mark pro trigger (the internally adjusted ones) and noticed it seems like theres this clear stuff covering the screw for what I thought was the weight adjustment. Anyone ever had this before? Wasn't sure if it was just a drip of hot glue or what, and if I should stick some...

    Gunsmithing Chambering a barrel through the headstock?

    Never have even touched a lathe before so forgive me if I sound stupid. How far can a barrel stick out of the headstock/spider/dohicky unsupported when chambering? Reason I ask is if say your spindle bore is only 1" but your chambering a barrel with say a Rem #3 contour where the barrel...

    Gunsmithing VFD on a lathe?

    I've been contemplating on buying a small cheap lathe to both learn how to operate one and to do some barrel work just as a small hobby. Anyways, I've noticed some of the cheap new lathes from like grizzly use single phase motors and don't really go lower then like 150 rpm so I was wondering...

    Wet Tumbler RPM range?

    Just wondering if anyone had any suggestions for the RPM range for a wet tumbler? Was thinking about using a blower motor I have laying around, 1/4 hp @ 1725RPM single phase, and mounting the PVC tube directly to the shaft and supporting it on the other end with some casters or something. Had no...

    Rifle Scopes EGW or TPS Rings?

    I already have a EGW base (non-hd version) and was trying to decide between the TPS TSR steel rings or the EGW HD rings. The EGW rings are still aluminum and cost nearly $30-$40 more than the steel TPS so my question is basically would it be better to match up manufacturers even though the rings...

    Gunsmithing Miles Gilbert Release Agent for JB Weld?

    I was going to "bed" a scope base, got some JBKwik and planned on using some Kiwi Black shoe polish I have on hand for the release agent but I found a Miles Gilbert Bedrock kit my buddy used a while back that still has a good bit of release agent in it, was wondering if anyone knew for sure if I...

    Why isn't the most accurate load the max load?

    Okay so I know you should test a variety of charges between min and max to find the most accurate for your rifle, use the ladder test, etc. My question is why is that? Like, what does varying charges affect holding all other components constant other than velocity? Thanks. The cartridges in...
