Please explain barrels- I see references in ads for 14.5' barrels. doesn't some one like me need a 16'?
16" total, yes.
You can achieve that by using a 16" barrel, or a 14.5" barrel + a permanently attached muzzle device.

It'll work with any standard lower

Dubi - adding an ambi safety to my 15-22 is on my to-do list, why will S&W parts be my only option?
I was incorrect above about M&P being sole source. Mr dubi says 15-22 ambi's are just not common.
"Pricey" because they cost 2 x as much as AR ambi.
He bought me this one.
Dr Boogs, you can try mine when we go shooting!
Works for me!
Because the M&P 15-22 uses a non-standard lower and receiver extension, you have to use the BAD lever. I don't recall where I got it; from BAD, Joe Bob's, Primary Arms or someplace else.
Question about handguard length
I am building a 300 blk that will eventually be a 2 stamp gun.
1st, what are the main differences besides length in a 9" and 10.5" 300 blk out barrel? Does the length affect sound suppression or ability to run subs?
2nd - choice of Handguard length. There are both 9" and 10.5" handguard lengths. If I buy a 10.5" barrel and 10.5 handguard, will the handguard extend past the barrel? I plan on adding just a basic flash hider till I choose a can and wait 9 months for the stamp.
I have not assembled an AR before, but this thread has given me the assurance that I can do it.
I didn't know how with a barrel nut and how the handguard marries up if a 10.5 handguard will stick out further than a 10.5" barrel without a flash hider already attached.
Thanks y'all!

Not past 8" which is generally accepted as the optimum length barrel for 300 blk.

The handguard will extend to the end of the barrel (past the threads). Most people that run cans on weapons with less than 10" barrels get handguards that cover some if not all of teh can as well to extend a rail another few inches.

You can always buy the barrel first, and measure what you have to work with when it's mounted to the upper. Takes more time, but avoids problems.
So should I look more at going with an 8" barrel then for optimal performance?
I had originally thought using 9 or 10.5 so I could still fire and be half decent since it will probably be a year until a can goes on.
I didn't know 8" was considered optimal.
I am looking Kak Mr blondes barrels, any other suggestions that I should consider?
Thanks!

quote:Why would a longer hand guard make it hard to remove the can? It definitely would be harder to remove/replace a muzzle device, but a direct thread or quick attach can doesn't really have issues being installed/removed with a long hand guard.quote:I'd actually prefer to get a hand guard that is about 1 inch shorter than the barrel so you can easily remove the can- unless you don't ever plant to take the can off.quote:

I think he means that you can easily remove the can to shoot it unsuppressed.
I used a 12" hand guard on my 8" 330Blk with a QD YHM can. It's the perfect setup in my opinion if you don't have any intention of shooting unsuppressed.
That's my whole thing about handguard length and barrel length. It will take so long before I have a can, so I would like to have some fun in the mean time.
I think I will just get a 10.5 Midwest hand guard and a value line kak 10.5 barrel.
Then in a year from now I can get the better barrel once the can is purchased.
The handguard price difference doesn't go up much from 9-10.5, so I'd rather only buy that part once. The value line Kak melonite is only 100.
Thanks for the help guys!

You can. You'll just need some extra hardware to safely pull it off.

Is this in the same category as Shockwave Blade? That it is more of a brace than stock?
It's a full stock. Will be going on an SBR

A compensator directs gas out of ports on either side of it. That gas has enough pressure to split a hand guard when it's installed over the muzzle. It also has enough force to burn/remove fingers like a cylinder in a revolver. The device schmelba posted helps contain the gas

Tamukid,
Skip to 2:23 to see what the blast does directly beside the brake, with and without the deflector.
The blast deflector you see in my photos is made by YHM, and connects to the flash hider the same way my suppressor does. Well, the same way my suppressor will. Assuming I ever get it. This wait is killing me.

Very interesting.

Haven't gotten to play with one but that style intrigues me too.
Another option would be a law folder and a LWRC ultra compact.
quote:I went ahead and bought one from Primary Arms. Dealer pricing was a decent discount. I'll send it back if it sucks as bad as an A3. If this one doesn't work out, I'll try the MVB version which is a bit more compact. I'm building up a PDW and want something a little lighter/more compact. A standard buffer/tube is ~10oz. My go to STR stock is around 12.5oz. The Tomahawk is supposedly 10oz total.quote:
