Just submitted a SBR this morning, and now just trying to figure out how to build it up.
Submitted this as a SBR .300 Black-Out with a 10.5 Barrel (have one on the way)
Now to build it up for a 30 cal Suppressor.
Starting with a Spikes Honey Badger lower.
Going to build this slowly over time (if I don't get impatient lol).
This is my First E-File Form 1 and my first SBR.
Questions I have are:
1. What Rail works with most Suppressors
2. What Suppressor to get (Probably a Dobbs Defense)
3. What Trigger group
4. What Stock

And I do know I can not assemble it till stamp is approved.

Stock:
Any by Daniel defense or mission first tactical if you want a minimalist look.

But since you are going to suppress it, maybe a magpul ubrt, or just a crt.

1. Seekins
2. Dobbs
3. BCM gunfighter
4. LWRC


You can build it now, just wrap the buffer tube in papracord, tape, whatever and keep the stock body in the back of the safe until you get your stamp.

Can I get a .45 cal Suppressor and use it on the 300 or would it be wiser to use a 7.62 Suppressor so I can use it for both 308 and 300 BO?
Not sure on Suppressors about what works with what, As I also want one for .45 Cal and to use on my 1911 as well.

1. seekins (nws said), odin works, yhm diamond or light weight quad (they're not light weight)
2. dobbs, specwar, or saker
3. how much do you wanna spend?
4. mft minimalist or whatever floats your boat

You and I must think alike. I have a lower I picked up and the LPK. Now I need to get it engraved and figure out what upper to start putting together and get the stamp started for that while I wait for my Dobbs can to come back.

Honesty as long as it isn't a slim designed rail it will probably work. primary arms has the inter diameter of most of their cans posted.

If your doing rail recess, then I suggest a direct thread can or something like the Dead Air Armament can which doesn't require you to reach a lever or collar that will be under the tail.

Looks like I might get a RRA 2 stage trigger I am not going after 500 Yard shots with this build, but Hey you never know.
I have shot an AR with this in it and it performed OK.
Still Looking at Rails and you guys have given some Great Suggestions and I like Troy, YHM, Seekins, and Odin so far will be hard to decide which one.
As far as Money to spend (I don't want to break the bank but a little is OK).
And the Suppressor suggestions are awesome I like reading about each one.

I'll third the Seeking rails...particularly the MCSR. As to suppressor, as has been said, true, only subsonic through a .45 can....but you can't shoot .45 through a .30 cal can. Just a thought when it comes to modularity and getting the most out your purchase.

As to stocks, check out the Ergo F93. It counter balances suppressor weight nicely and I like it much better than the UBR (lack of) consistent cheek weld.

As to FCG, I alway prefer a single stage trigger in AR's. Just my preference.

Every trigger I have ever seen fail on an AR has been a RRA 2 stage. I wouldn't put one in my rifle, but that is just me. Honestly I really like the ALG ACT trigger.

That Ergo F93 is SWEET will have to really think about that.
Might even get one for my Daniel Defense DDM4

Just Checked that out will give it a Shot I have never had the RRA in mine and will try out the ALG ACT trigger (just Ordered 2).
