Hello again :o

When I started building my SPR I picked up a spare forged Rainier Arms lower. Then I really wanted to build it ... and it started.

Form 1 is files and the build began.

I really want this SBR to function well all 4 ways possible. Super - Suppressed and Not and Sub - Suppressed and Not.

I think I would like to run 8.5 barrel with adjustable gas.

Feel free to comment and discuss and recommend parts and accessories [:D]

Here is what I got going so far.

RA Forged Lower
Fortis QD back plate
Battle Arms Development Safety Selector
MFT pistol grip
Magpul MOE stock - Upgraded to B5 Systems SOPMOD Enhanced Stock
Magpul Alum Trigger guard
ALG Defence ACT Trigger - measured at 5lb.7oz pull very consistent pull after pull, crisp break <- great for the money!

Upgraded ALG to Giessele SSA-E

Also gearing up for adding 300BLK to my reloading calibers. Ordered Forster Ultra Micrometer Seater with FL Sizer, Sheridan Slotted gauge, 110gr and 208gr AMax bullets. Picked up 1000 ready to load brass and 500 150gr FMJ Hornady bullets. Ordered bunch of powder =)

^^^ I have to agree I I think you'll get along well here. Just watch out the to compu-octopus. He'll steal your soul... He tried to take mine today but I was able to hold on to it just barely...

But seriously, great build and great pics!

Edit: build looks good and parts list looks on par. What barrel are you planning on running and what adj gas block?

I just wish I could have a bench like that. All I know is you've got one heck of a camera Seattledude

thank you!

Camera is my old Nikon D200 nothing too crazy here =)

Bench, yes I love it and you can get your own from Uline, they have warehouse in Auburn for pick up.

I have two of them. One pictured for my progressive press and gunsmithing (Maple Top 72x30) and one for my Presicion Rifle reloading (Maple Top 48x30)

I also added top shelf on both benches. Great bench! Very Very sturdy and legs are adjustable for sitting or standing.

Very nice. And that's pretty good for a bench that nice. My problem is finding room for it... You think I could put all three in one room so I could get me a man cave 😜

I've been eyeing the uline benches for some time. I'll have to wait until our move later next year though, to properly setup my work space. The more pics I see, the more I want that bench!

Turned out very nice. I just love the look of a well finished forged lower. Funny part is I have that exact optic in that exact mount. My Bobro is the Trijicon badged one though.

I'd pin that gas block.

Otherwise, looks great.

Being semi auto and very soft shooting 300BLK I really dont see a need for pinning it. I wll not be doing any mag dumps or high rate of fire for any extended periods of time.

Its dimpled and installed with high temp rocksett.

But thank you for the comment =)

Here's a buddy's gun after a 400 round day of suppressed 300 BLK shooting. He couldn't figure why he had a single shot gun and brought it over.

Generally, I get all my gas blocks pinned. If you're just going to use it as a range toy, then yeah, the worst that'll happen is, your day will be cut short.

SeattleDude
12 February 2015, 21:31
Yup. For now it will be a low volume shooting gun. My range only allows 1 shot at the time 1 bullet at the time and 300BLK is not exactly cheap even though I reload.

I don't plan to shoot 400 rounds a day or 200 or even 100. So I will keep an eye on it and if more shooting will be happening, I will consider pining.

Syrac doesn't have a hole for pinning. Is it ok to use pining jig tool and drill your own hole?

SINNER
13 February 2015, 05:21
Yup. I use a BRD jig but they are gas block specific. I do not taper ream and use a tapered pin, I just use a roll pin. As a test I installed a VLTOR gas block with a roll pin and removed both set screws. I put over 2,000 rounds through that barrel before I re-installed the set screws. Lots of back pressure acting on that gas system with a can. I have seen well tested guns have the gas block shift first time a can was ran on it.

Curious if that barrel was dimpled or just tightened on the barrel?

Looks like we're moving this summer. I think I'm going to get a couple of those uline benches. Where's the best place to order those from? Direct?

It was a dimpled barrel. Sorry I didn't see this before.

Just curious but what benefit would be brought from pinning the gas block? What does it all entail to pin one? Can you elaborate please?

Simply using set screws to hold a gas block in place is not sufficient in my opinion. The gas block can and will move with use. Look at the picture several posts above.

You'll need a gas block like an 87 Industries one to do it yourself, or a drill press and the correct bits to do any gas block.

waiting for RA and BRD to make a pinning jig for the Syrac adj. I was gonna use mine on the 14.5 noveske build but a new friend told me some horror stories compared to a standard pinned bcm/RA/etc GB.

Anyone got a lot of rounds on a Syrac yet?

I have a hundred or so on each of two units with the Syrac adjustable. Zero issues suppressed or un-suppressed; and I have not "adjusted" it. But that's not a lot of rounds IMHO.
