Try the ones sold by Black Rifle Arms in Florida, they are the only ones I would use in the bolts we machined. They are thicker on each side of the stiffener instead of dished like most extractors.
I'm pretty sure he means BOLTS not BCGs. Actually bolts and barrel extensions since those are the 2 parts that take the most shock.
He's heard my opinion before so I wont get into it.
Carriers can be Nitride/Melonite QPQ treated with no issues because there is very little shock load...only at...
Seems the OP chose a 224 Valkyrie-
"
Pulled the trigger on the RA ultramatch 20" .224 valk...I think it will fit my needs better than the .223 and current supply for supporting components is night and day better for the valk than the arc.
I appreciate everyone's input on this and I look...
I Think all of the 6mms beat it and some of the .224 calibers as far as less drop and drift. 6mmAR/243LBC/6mm Predator/6mm Grendel, 6mmARC, 6PDQ, TAC6, 6mm Hagar, 6 WOA, 224 Valkyrie, 5.56x42, 22 PDQ, 224LBC, 22 Grendel.
That has nothing to do with the argument we had over a several year period on arfcom. Remember posting a photo of a chip on a melonite treated barrel extension you purchased from me about the size of a pin head as proof melonite was not good for an extension? I'll see if I can find it in the...
"SixFive-0" above is John Hanka, owner of Six-five Outfitters and the Grendel forum, producer of the Ultrabolt.
What I can't figure out is LRRPF52 is his buddy who spent years, like 6-8 telling me how Bill Alexander told him hydrogen embrittlement due to Nitride /Melonite was a bad thing. Now...
You are right, I have retired and probably have less than 100 barrels left. The only 18s I have are stainless and are a lighter profile after the 3 gun guys said they wanted a faster swinging barrel.
Opinions LOL. The Maxim bolts made from 9310 are probably better than most, at least they are not Nitride/Melonite QPQ treated. I would go that route before buying a nitride treated Ultrabolt.
ETA- Bolt lugs are .100" thick but the web between the lugs is only around .040". That web if too...
I'm not saying Wilson is the worst because I have tried almost every manufacturer in the country over a 14 year span, some with BIG names. It is hard for me to believe companies selling complete rifles for $2000+ have barrels that are absolute crap. A crown is a simple thing to cut if you know...
Wilson blanks with WOA finishing the chamber and crown are good, but I wouldn't buy a barrel completed by Wilson Arms. I had 200 of those made and not going back there. Cutting the chamber concentric on the bore and a good 11 degree crown are 2 important parts of an accurate barrel.
What kind of barrels are you paying $1000 for? A short chambered Krieger DCM runs $295 or did last time I purchased one.
ETA- nevermind, I wouldn't pay a K for a proof when a Krieger can be had completely finished for half that.
Nitride treating a bolt or barrel extension after it has been gas carburized(proper heat treat) will soften the lugs allowing them to compress over time which will increase headspace. Bolts and extensions should be gas carburized(case hardened) to around 60 rockwell c but the core in the thin...
I don't know, sold my Harleys 4-5 years ago. I know the Harley shop in town does not stock anything but the harley brand of oil so If they take it in for an oil change that is what they get. I always used Amsoil. When in stop and go traffic air cooled Harleys can heat up, when they do they pop...
I don't know where this came from but it's pretty funny.-
"The AR scene is such a gimmick, and to me, they're the ultimate bling gun, every tom dick and harry has a 16" essentially useless weapon other than to suck money out of the pockets of the clueless. My neighbor ran out and bought the...
Buy a better barrel and shoot factory 140s out of it...or try 120gr SMKs. Yeah the BC isn't great but if you can't get good accuracy with that bullet there is a problem somewhere.
