SBR side project

[Big_Tom]

Ok well I've decided to as a side project to start a SBR. I've been following Pyzik's SBR thread and have been on the fence about either building a 300blk or 5.56.

I've have been wanting a 300blk for a good while and but as stated before I don't currently have cans and don't reload. So I decided to just go the 5.56 route till I get can and start reloading then just build a 300blk upper.

So now I need to figure out which of my lowers gets the special treatment. And if a 10.5" BA barrel for $98 is a good deal or not. [BD]

No cans, no reloads. 5.56 was the obvious choice.

Here's the chosen one

I should have some parts drop sometime this week.

Ill be installing a pistol tube till I get a chance to get the form 1 sent and approval back.

One thing that I am looking to do is to install a blast shield or flash can type muzzle device. I would like to have one where I can remove the shield from the flash hider/break so I can install a suppressor once I decide to get one. I hope to be putting in the paper work for one by the end of 2018. I've been looking at different suppressor companies and their blast shields. And seeing I have no experience with them I would like some input on which to get. I know its not a good idea to get parts that their design may change and have to find a discontinued suppressor.

The thinking behind this is that I know with most suppressors a muzzle device is included. So I plan on going with a .30 cal suppressor and swap it between my 5.56s and .308. If I go ahead and install a muzzle device and blast shield on this SBR then I can install the included MD onto my .308. If it works out then great. But if a design change makes the 5.56 MD non-compatible then I'll have cut my loses and get a new one. I do plan on getting a 5.56 suppressor but figured .30 cal would get me by till then.

Here's a few companies I am looking at:

Griffin Armament
SilencerCO
Surefire
AAC
DeadAir
Gemtech

I can only talk about the Griffin Armament (the rest I know nothing)... I am more than pleased with their products by far. I have two more rifle cans in jail right now as I type. Their taper mounts are awesome and provide a lot of benefits. I also have their blast shield but I never use it. All are cross compatible.

It's unlikely that the taper mount will be going anywhere.

The mount is a big part of the reason I went Griffin. It has all the benefits of a thread on can without technically being a thread on. You can get the exact same suppressor orientation every time with that mount. You can shoot a shot. Take the can off the gun. Shoot another shot and your baffle alignment is spot on every time. For precision shooting it's fantastic. I've even heard of a test being run with Griffin cans where they had 5 cans, shot a single shot, removed the can and replaced it with another can... and did a round robin....and wound up with a sub MOA group using one rifle and 5 different cans on it. I definitely believe it. After seeing what mine can do that is not a stretch at all.

Also the GA one won't wear out. There are no buttons or teeth or anything like that to wear out. It is also compatible across multiple suppressors. If you say start with a 7.62 can and later buy a 5.56 can the outer dimensions of the taper mount is the exact same. Swapping between guns is no big deal and you can do it a million times and it will never wear out. It's also cross compatible with multiple other Griffin cans.

I have nothing but good things to say about Griffin suppressors. That blast shield though, what would be your point of using that? I bought one because I had a gift certificate and it ended up costing me like $5 but honestly the blast shield fad is just that. A fad. It might have some limited use in some situations but overall my opinion is the blast shield thing is not really worth it.

[Former11B]

Griffin Recce 7.

I have a Recce 5 and it's fantastic. Both are well built, offer great suppression and are on the lighter side of the .30 cal can scale.

I like the variety of mounts Griffin makes from brakes, flash hiders, comps, etc

[alamo5000]

Griffin actually has two lines that fit your bill. The SD line which is a quick detach. The other is the taper mount. Both have benefits I imagine. I only have the taper mount and have never tried the SD system. I don't have any interest in the SD (QD system). The taper mount is perfect for me. The above mentioned precision shooting aspect is way more valuable to me and my style of doing things.

As for the blast shield itself.... watch their video on it...

Yes. LOTS of choices from comps to brakes to flash hiders... taper mount is where it's at. Lots of variety and options that all are still taper mount.

Between me and Former11B you will be talked into Griffin eventually [:D]

Well I'm leaning towards them as of now. The taper mount brake and blast shield are about $180 together where others are about the same for just the BS. I don't know if saving me a few dollars now will cost me in the end. But I do like the idea of no moving parts when dealing with the taper mount.

I will sell you my blast shield if you want. I don't use it.

As far as the 'saving a few bucks' comment... it won't 'cost you in the end' at all... not in this case. You're not going to lose out anything in this case. Griffin came up with a simple yet very effective design. No do-dads, thing-a-mabobs, ratchets, or wigits to get lost or screwed up (or wear out). It's just simple and very effective (the taper mount). In fact it's MORE effective than many if not most other mounts on the market (given I am talking about specific uses).

The mount was probably 75% of the reason I chose Griffin to start with. Don't get me wrong... it has superior suppression to most other 5.56 cans out there (I am talking the Recce 5) but the mount is one of the major reasons it's great.

If you want to be able to QD your suppressor there are other options. If you want repeatability and precision as a premium over QD I challenge you to find anything that comes close.

It has all the benefits (and more) of a direct thread (for that use) without being direct thread. Griffin's QD on the other hand is not nearly as 'precision oriented' so you will have more POI shift ongoing because the can can be oriented different ways every time you put it on the gun.

I may take you up on your offer, and then you really would have me talked in to GA.

Very clean looking lower - I like it.

[Big_Tom]

Very clean looking lower - I like it.Thanks that's why I like the smooth side lower. It's just so clean.

The next step is to get all the paperwork filled out to register it as a SBR. And when I do I will have to engrave it as well. I really want to keep it clean as I can. So I was thinking about getting it done on the feed lips of the mag well.

I believe it will still fall under the correct terms of engraving a NFA lower. Does anyone not recommend getting the engraving done there?

You can get the inside of the trigger guard engraved by most places, which will keep it external, yet unobtrusive and avoid nicks and dings the magwell might get over time.

[GOST]

Joelski who are using to engrave inside of the trigger guard on lowers with integrated trigger guards? I've got mine engraved there but it's a regular forged lower.

[alamo5000]

I have a CMT SBR and I engraved mine on the bottom of the trigger guard. It worked perfectly. You have to turn the gun upside down to e even notice the engraving.

[GOST]

Where Alamo said would look good. If Joelski has the someone that'll engrave the inside next to the fire control opening that would look good also.

[Joelski]

These guys say they can do it with the trigger and hammer removed.

[GOST]

Joelski they can engrave on the inside of regular forged lowers, and outside of the trigger guard if it's fixed.

Dude that place is legit. That's the place that did this engraving for me.

[Big_Tom]

Yeah bottom of trigger guard will work if I can keep it from messing up the CMT ammo grade logo. Lol.

Ok I've think till I get into 300blk. And to have something different than 5.56. I also want to do a 7.62x39 upper. I don't know if I will do it or not yet. But what would be good barrel length to go with? I would like 10.5"

I had Ident do a few of mine. Maybe they changed but they wouldn’t do magwell lips. I won’t use them again because I didn’t like their placement nor their turnaround time. Veritas has been my go to and will send you a pic of what it will look like for final approval before they start.

I’ve seen engravers advertised as doing inside the trigger area with a billet solid trigger guard in place. Can’t remember who. It’s out there.

[titanse05]

I'm just dropping in to say that you are on the right track with this build and that Veritas Machining is good to go. Their communication is excellent and as fledge said, they send you a picture of the engraving placement on your lower to make sure your happy. Plus the turnaround time is great.

[Big_Tom]

I got home from work and was surfing the interwebs and decided to start the NFA process using the Silencer Shop Form1 process and single shot trust.

Everything has been submitted for review and all I have to do is get finger prints scanned at a kiosk. Which I won't be able to do till Wednesday.

If you ever wan to sell an NFA item, put buyer on trust, remove yourself, done.

Ok guys well I ended up with Farva's upper. And so the upper I was going to do for this build is on hold. Also since I still needed trigger and safety I went ahead and bought them.

I still need some sights or a cheap inexpensive red dot. I want to go with ScalarWorks Peak sights later but right now just want something to throw up top. I may take a look at something from Primary Arms or Holosun.

Would like to stay under $200. This isn't a permanent sight just one I can use for new builds till I get what I really want for them.

I built the original planned upper. It will be the future home to a suppressor sooner of later.
