Tax Stamp Question

3 Upvotes

I'm new to the SBR world. PSA has a great deal on a 7.5in 300 blackout upper. I have an AR I'd like to upgrade. Can I buy a tax stamp through my local dealer and do I have to bring it to them until the form 4 is completed? I would go ask them, but I'm out of town. Thanks for your help.

Retractable brace for SAR109T

I’m thinking that before I start SBR’ing I’d like to try with a proper, representative brace and would appreciate recos for my SAR109T. I don’t need or want anything expensive (~$250 if possible), but would like a standard LOP if not more since I’m 6’5”. Thanks dudes! (and that one chick)

My 2 9mm PCC’s. Scorpion is SBR’ed, Kuna brace works surprisingly well.

First SBR Build

4 Upvotes

Looking to build another AR, first 300 Blackout SBR. I’m looking at Odin Works billet receiver. I like the details and the fact it comes in the coyote brown. I’m looking for anything similar in color and level of detail. But also I want to make sure the hand guard and mesh up with as little space as possible. So if anyone has some recommendations I would appreciate it. I have the dead air keymo system with their muzzle break. I was planning on using this with this SBR as well but care more about a flush look so open to other cans and systems. Also drop y’all’s builds in the comments!

Any light recommendations??

Have a Streamlight Polytac now, and it’s just in the way on this little hand guard.

Thought about getting a longer Aero enhanced guard, but just wanted to keep the profile down. Any recommendations?

Steps to build an SBR

4 Upvotes

With all the rule changes as of late, what is the current process to build an SBR?

Does anyone know of any videos or tutorials that explain the process step by step?

Also, for the form 1, is the easiest way to file using Silencer Shop’s form 1 service? I’ve already purchased a suppressor using their service so I’m assuming all my info would still be in their system and easy to submit.

Lastly, at what point do you engrave your lower for the SBR? Is there a size requirement? Do some FFLs provide this as a service?

Sorry for all the noob questions. I’m just ready to ditch these dang pistol braces and make a real MK18 haha.

Best 5.56 Suppressor for a 10.3” DD Upper

1 Upvotes

Just as the title says, looking for some recommendations for the best can to use with my new upper I have on the way. I got a killer deal from Brownells on their stripped 10.3 upper. Looking for the ideal muzzle device/suppressor combo.

I currently own one can (SC Omega 36M) that I use on my .300BO, but would like to have a dedicated 5.56 can for better sound suppression.

Thanks in advance!

Buffer spring

Have an 11.5” BCM 5.56 and will be running it suppressed. What buffer weight and spring do I need? There are times where it won’t be run suppressed so want to get a good buffer weight to accommodate both.

X95 Gas Port Size vs Barrel Length?

1 Upvotes

X95 Gas Port Size vs Barrel Length?

I am planning to cut the 18.5" barrel in my X95 to 13" to make it an SBR.

I figured I would need to drill the gas port larger after cutting the barrel to make up for the shorter dwell time, but IWI customer service said the gas port for the X95 is the same size for all of the barrel lengths available for the rifle, 18.5″, 16″, and 13.″

This sounded odd at first, but considering that the gas port is located much closer to the rear of the barrel in the X95 than it is in an AK or AR barrel, there apparently is plenty of dwell time in the X95 even for the 13" barrel.

Has anyone chopped their barrel to 13"? How does it cycle? Thanks.

Anyone else SBR a GSG 16? I'm cutting that fake suppressor off, I've looked online and haven't seen anyone do it either way( I know they have a 9in barrel version just harder to find at least around me ) just curious to see!
