@TonyRumore any chance of a 375 raptor? I regret selling my .358 Socom setup, but I am itching for a SFAR

There is a very good chance we will make some SFAR barrels in 375 Raptor.  
We are currently in the process of making some Raptor barrels for the standard AR-10 and it would be no trouble making some with our new SFAR barrel extension.
It fits in well with our current product line, since we already buy bulk 375 caliber barrel blanks for the 375 SOCOM barrels.

Very cool.  What kind of metal are you using and is it special?  I know Ruger advertises a special metal but is it even necessary for the extension?

A 375 Raptor SFAR is appealing .

Honestly- kind of interested in a 14.5  6.5 Creedmoor.  As random as that sounds.

Pin and weld.  I suppose 14.7", if I get to be picky.

I thought about making some short (10-12") barrels for the SFAR, but with Ruger only selling complete rifles, I'm not sure how big the SBR market is going to be.

True enough - but the barrel life of a 6.5 Creedmoor is about 3000 rounds or so.

A tactile light action shooter 6.5 CM, is going to burn through that pretty quick.  I wore out my PSA PA10 one in about 2-3 years, (pulled it, and cut it down to a 14.5 Grendel)

Meaning there is a market for replacements due to consumption - and no route to replace a worn barrel with an alternately configured one.  The guns are so cost effective, I very well may end up with both a range performance unit (i.e. 20")  AND a tactical unit.  And if I'm going tactical unit, and already have a 20 - a 16" isn't short enough to bother.  But a 14.5(7) P&W is.

Donno how much of the market I represent, but that's my interest.

You're already making receiver extensions.  If you can make receiver extensions, you can make bolts.  Make a bolt that fits a standard AR carrier, uppers & lowers from billet, and Bob's yer uncle!

What gas length did you go with on the Grendel barrel, what profile, and did you have to plug the Creedmoor port?  Pretty clever reuse of a barrel, but sounds complex.

I wanted a light weight 14.7 Grendel BBL, and at the time that wasn't commercially available.  

Whack off the ends.  Mill down the HBAR. Tap and plug the gas port.  I went midlength gas, runs great.

It shoots great and I run it on a magnesium lower as my hog gun.  Love it.  A lot.  Imagine having about that same gun at about the same weight, in 6.5 Creedmoor...





(Well- while I'm dreaming - would LOVE 6.5 Grendel bolt and barrel w/ extension for the RDB out of the new alloy.   Imagine that RDB 17" BBL on the right, running 62,000 PSI 6.5 Grendel.)

Wondered how you dealt w/ the gas port.  What thread did you go with?  Did you cover the grub screw with a collar on the barrel, or is it just under the handguards?

I think after you take the bolt and extension out of the equation you're still left with the Grendel brass 58ksi max limitation.  Still would be a significant improvement though .

* 58 is 93% of 62

Also a reason I'm fascinated with a .204 based .257-.264 ; similar case capacity as grendel/spc after necking up , but 60ksi with mere mortal metallurgy...though that pesky magazine thing while loading out to 2.5x" .

Meaning there is a market for replacements due to consumption - and no route to replace a worn barrel with an alternately configured one.  The guns are so cost effective, I very well may end up with both a range performance unit (i.e. 20")  AND a tactical unit.  And if I'm going tactical unit, and already have a 20 - a 16" isn't short enough to bother.  But a 14.5(7) P&W is.

Donno how much of the market I represent, but that's my interest.


What gas length did you go with on the Grendel barrel, what profile, and did you have to plug the Creedmoor port?  Pretty clever reuse of a barrel, but sounds complex.

I wanted a light weight 14.7 Grendel BBL, and at the time that wasn't commercially available.  

Whack off the ends.  Mill down the HBAR. Tap and plug the gas port.  I went midlength gas, runs great.

It shoots great and I run it on a magnesium lower as my hog gun.  Love it.  A lot.  Imagine having about that same gun at about the same weight, in 6.5 Creedmoor...

(Well- while I'm dreaming - would LOVE 6.5 Grendel bolt and barrel w/ extension for the RDB out of the new alloy.   Imagine that RDB 17" BBL on the right, running 62,000 PSI 6.5 Grendel.)

I think after you take the bolt and extension out of the equation you're still left with the Grendel brass 58ksi max limitation.  Still would be a significant improvement though .


Yea that's the big one.  If not careful, brass could be intersting- I don't know if I'd really go to 62,000 psi


Steel case head, aluminum washer, & brass case gets you to 80k.

Really thinking about one of the 16" SFAR's to go with an InfiRay RICO GL35 Thermal I bought from Arms Unlimited on sale. Really like the concept of it being light so by the time I add my Sandman S and the thermal it won't weight all that much, plus having .308 for dispatching anything that might show up at night.

Well, I pulled the trigger and got a 16" SFAR in .308 to put my new thermal on. I also got one of the HBI rails I saw in this thread and it actually seems like a nice option for a drop-in rail. The rifle has had some teething issues but nothing serious or major; just one FTF and one stuck case in the 120 rounds I've put through it, but it seems to be breaking in as it's running more smooth as I put more rounds through it.

Mass production guns tend to be like that.
The money you save on the gun gets spent on ammo for break-in.

Anyone have experience swapping buffers/gas blocks/etc? I put a Riflespeed on my 16” with midlength gas, but the one time I went out and shot it the gas block slid free. I put it back on and rockset the screws but haven’t had time to get back out to the range. Anyone using a rifle speed, did you need to swap plungers?

As for buffers, I’ve read multiple people just swapping the buffer tube for an A5 length, throwing in a tubbs AR10 flat wire and either an H1/H2 or even hydraulic buffer. But I’m also reading people are having failures with H2’s and some H1’s after a shooting session due to the weight.

So for those of you who’ve done mods to the gas block/buffer what did you do to make yours run fine?

Has a single person successfully swapped buffers or anything like that and had a result better than the setup the rifle came with? I can't find anyone who has. Mine is coming back from Ruger now, hopefully it will be here this week yet. They say it is working now.

I've made a few minor changes on mine, put on an Aero AGB, and played with standard buffer weights. Mine is pretty much always suppressed, I've had the H buffer in since before swapping the GB, and preferred the recoil impulse over the H2, also had some lazy cycling with the H2. The AGB has helped a little to limit brass damage, but hasn't stopped it all together, I think ta mid-length .308 is just going to be a bit rough on brass no matter what you do, at least that's been my experience in the past. Shoots fine though.

Gonna be tricky w/ a single gas key screw.  For any short stroke piston to be reliable you'll probably need to machine a monolithic carrier.  Could be done, but what do you gain?

You should be able to use the Adams Arms carrier.  Might require slight modification, but it should be doable.

I believe so . I hadn't gotten too deep into it myself as I'm not looking to mod to .473 ... more so .378 . So I'm aware that a std carrier will need relieved for the ar10 mag and the cut out for the fcg . The ruger FP has a specific journal and pinning point ... different than std ar15 . I linked the video because he has all the dimensions and what not involved .

I got mine back today. The notes say the chamber was honed, and it was test fired 20 rounds with no malfunctions. Looking with the bore scope, the chamber definitely looks smoother. The shoulder is still a little rough, better than it was, but the rest looks really well polished. Fingers crossed it does better now. The weather looks good this weekend, hopefully I'll get to do some shooting sunday.

But we're talking about the carriers, not the bolt or barrel extension.  The location of the ramp might be a nuance that can't be overcome.  Everything else is within modification range.

I sent a rude email to Ruger regarding their gas block. Mine is in full contact with the rail and there's less than a mm on the other side.

I told them I'm not going to send it back until they have a better option. There's a pretty good chance this one would contact the rail during recoil, even if it wasn't already touching. I'm sure their engineers have already brought this up.

Bean counters can suck it:

Yep. Mine was like that too. I sent it in, for that and another issue with the handguard. They replaced the handguard and did nothing for the block. I bought a suppressor ready rail from Midwest Industries because I didn't like the chincy rail anyways. I could not straighten the block because it would slip right back into the "divit" when I was tightening the screws. The new rail just barely cleared the factory block. I deliberated between my options of riflespeed, a standard gas block with a 50/50 BRT gas tube, or fixing it. l finally opted for option 3 and took it to a smith and had him straighten it and dimple the barrel. I had him shim the barrel while he was there. That cost me 60 bucks.

I ordered the superlative arms clamp on block, should avoid the dimple issue.

Absolutely.  If you track back on the gentleman doing the mods in the video , he has a thread where he documents all the differences between  ar10 , sfar , ar15 ...and pictorally with a micrometer. I just used the vid as a reference point for anyone interested in doing their own mods . Also nice that he got into the differences between POF and SFAR for anyone interested. If there is anyone else doing such breakdowns or mix and matches , I'd be interested  .

A friend of mine invited me out to Big Piney Sportsmans Club here in MO, Friday. He just joined. They have berms with a steel gong at 100yds, 200yds, 300yds. They also have 600yd targets but no gongs at that distance. I didn't try shooting at 600.  

Attachment Attached File


I rang the 300yd gongs with the flip up iron sights on my SFAR. My irons were on but my Aimpoint red dot was off. Back to the 25yd sight in bench.  

My friend gave me an old can of South African 7.62x51. The Ruger liked it. However, it doesn't like my 2015 Lake City or German DAG.
My hope with this rifle is it would replace my M1A Scout.

So far that is not the case. My M1A eats everything. The SFAR is temperamental, preferring soft point hunting ammo.

Also rang the same gongs at the same distances with my 5.56 AR pistol with both irons and matching Aimpoint.

Both were shot sitting at a concrete bench off a sandbag rest.
