Hey....my bolt isn't shiny like yours, I'm jealous! Congrats, very nice accessories! When you get a chance can you tell me what that 223 barrel weighs? Thanks!
I’ve got a Gen 1 rifle and the first set of bolts were one-piece with the tear drop handle. I got some new bolts around 2012 that had the rounded handle and removable bolt face, both otherwise identical finish. Now that I have an M2 on the way, I ordered a new bolt and it not only has those new flutes on the body, but also that slick new finish. It feels a lot like NP3 but as far as I know Robar is no longer around to make it.
Side note, I ordered a barrel for the M2 well in advance last summer and last I heard from SAC the blank is still on order. If only Gen1 extensions fit…

Would that be a different finish than an A2? I have no experience with other Gen’s but I’d say mine feels NP3 slick. But like I said, I have nothing else to compare it to.
Will do! Just got to work, I’ll weigh this evening when I get home.
Yeah I don’t know what finish it is, I emailed SAC to see. It’s more of a chrome/shiny cerakote almost it seems compared to the other standard A2 assemblies. It’s definitely a standard A2 bolt with the fluting and all that. Just a different finish.
By the way, my slick shiny bolt came directly from DTA, so it’s not a finish that SAC is adding.
My 24" .223 SAC made barrel weighs as much or more than the 26" DT barrels I have so far... probably a scoshe more rather than just as much. It's really quite a heavy profile. Gotta be 7-8lbs.
Identical. So far I've got 2 of the silver bolts and 1 black bolt from an A1 kit.
It seems like NP3 - has the look and feel, but the surface is a bit more diffuse than the smooth NP3 parts I've had done in the past. Who knows what it is exactly?

On the new bolt coating, word is that it’s a nickel-boron finish that’s been added to all new bolts starting in 2022.
Thanks for the barrel weight HenryTheAce. Wanted to compare it to my SAC 16.5" (sans flutes). It does make a bit of difference in weight reduction
Lol meant, almost 4lbs not 14! but yeah, shaves some weight off. My 16.5” 450 bushmaster with same spiral flutes is 3lb 4oz (so another 10oz lighter than the 223rem barrel)…. Must be because of that big ol 45cal hole vs 223
Just think, for an extra four pounds you could have a straight contour 36” barrel.
I actually don't know... My m2 hasn't arrived yet. I just saw a thread about adjustable butt pads and was curious. My other bolt gun is in a mpa chassis with a lot of adjustments... Thought it might be nice. Honestly, with how slow it has been to get parts lately, I figured I'd start looking sooner rather than later.
Shooting without handguard ? Have new A2 with 23in barrel and not enough barrel sticking out to hang my Magneto Speed on. I know there are ways to attach an extension to the picatinny rail and mount it that way. Would like to avoid the expense and hassle. I am solely a hunter and after load development I don't use a crono. Can I remove the handrail, mount the Magneto speed and shoot for FPS? I am not concerned with resting on the barrel and influencing POI. I am solely gathering speed data, looking for that lovely flat spot in the curve. Doable ?
I don't know a ton about the MagnetoSpeed but I imagine that a possible solution would be to put an Arca plate right by the trigger guard and then just put it on a tripod to chrono so nothing is messing with your barrel
The barrel is firmly clamped into the action. No handguard needed. Just fire it from the shoulder instead of bench resting it while getting velocities.
I have an Arco plate and tripod. I am too afraid I would spazz out and shoot the MagnetoSpeed. Not sure the warranty will cover that !
Thats kinda what I was thinking. After all, the handguard does not touch or support the barrel (as intended). Thanks !
I'm not sure if you've misunderstood what I said or I'm misunderstanding what you've said. Let me try to be more clear. I'm suggesting you mount the rifle into the tripod via arca rail while the Magneto Speed is mounted typically (on the barrel). Or am I misunderstanding you?
Edit: I see you've found your solution. I mostly wanted to see if my message was incomprehensible haha

Can't mount the Magneto to the barrel, not enough sticking out past the hand guard. Sorry - if I misunderstood where you where going. I have seen some brave souls mount their Magneto on a table, apart from the gun. They line things up and shoot. I definitely would bugger up that process resulting in a high speed collision with the MagnetoSpeed. Would not end well.
I will try without the handguard. Not ideal, but workable.
Thanks all
Shot the 223 conversion the other day. Man that is fun! Liked it so much I ordered a 300blk one 
Yea just hit them with a small file or a cratex bit or similar on a dremel.
Interesting. I ordered mine in early Jan, at the time he said all he had in stock was some proof CF stuff and 16.5” 7.5tw Bartlein 223. I went for that. Did you order a different spec barrel?
I think I ordered in mid August. I'm not complaining. SAC always responds to my emails and really they are THE folks to get conversions from so I'll get it when I get it. I can't find the spec sheet, only the receipt, but I think I ordered their light contour, spiral fluted, 24 inch, black, 5/8x24, twist rate ? (whatever they recommended). Maybe they are just waiting to surprise me with all my barrels at once haha
Lol hopefully! Makes sense though. I know they get their stuff from Bartlein in batches. So Bartlein must’ve sent them a bunch of shorter DT contour 223 barrels in Dec/Jan so they had them on hand. What other conversions you got coming!?
Hell yeah, solid conversions!! That 450bm slams! I smacked a few whitetail this year out to 270yds with it shooting some bear creek ballistics ammo pushing a 240gr at 2520fps average in 16.5” barrel suppressed.
Would you say there's any less friction running the bolt ? Have you noticed anything vs the original bolts
Bit of back laying shooting with the SRS in 223 at 400yards. Certainly helps with fuck all recoil.
Haven’t spent enough time with it to notice anything. The difference is negligible so far imo
