Ideal AR Pistol Barrel Length?

DaemonAssassin said:

This is a build list I put together for a friend of mine, because he couldn't decide on rifle or pistol, so I gave him the choice of both. Just be sure to follow all state and federal laws.

Upper Receiver

Charging handle - pick one, depending on what you want to do

G.I.

Ambi - same one I have on my 300BLK

BCG

Barrel - Keep track of what you are using, because the handguard will be affected also

16" Barrel

https://www.kakindustry.com/ar-15-p...h/contract-300-16-inch-pistol-melonite-barrel

10.5" Barrel

https://www.kakindustry.com/ar-15-p...contract-300-10-5-inch-pistol-melonite-barrel


Handguard

If you are using the 16" rifle barrel, get the 13" handguard. IF you are using the 10.5" pistol barrel, get the 9" handguard.

You should look at a few others I've done. You might change your mind.

Looks more different now with a Seekins AFG, Inforce WMLx Gen 2, Magpul BUIS, SB Tactical SBA3 brace, and a Vortex Sparc.

What do you think of the Radical complete uppers (300 Black 10" barrel) that Joe Bobs sells?

DaemonAssassin said:

Serious pass. Build it yourself from quality parts.

I guess you get what you pay for.

DaemonAssassin said:

That is correct. Cheap uppers have more issues than Somali pirates trying to hijack a US Navy warship.

If I did my math correctly; just the upper parts in your list (I have all the pistol lower parts) adds up to $360.92 About the same as a PSA upper (except they don't have a 10.5" in stock). Price is right.

Anderson Manufacturing AR-15 Upper Receiver Assembly | $69.99
Anderson Manufacturing 6061 Aluminum Charging Handle, 10.99
KAK VALUE-LINE 300 BLACKOUT 10.5 INCH PISTOL MELONITE BARREL | 100.00
Strike indutries AR Mega Fins / Key-Mod Handguard Rail | 119.00
Yankee Hill Machine Flash Hider Phantom 5C2 | $36.00
Radical Firearms Low Profile Gas Block - .750" - Set Screw Style | 15.99
Expo Arms Pistol Length Gas Tube - Stainless Steel | 8.95

Total = $360.92

NOTE: I have a BCG and bolt already

Difference is crappy components and shoddy workmanship versus good components and good workmanship. Build, don't buy cheap uppers.

Makes sense. So all I would need is a reaction rod or some other device to hold the upper in a vice. Do you use a scope to get the gas block lined up with the port?

[EDIT] One thing about Odin Works barrels; I see they have a mark to line up the gas block, which they include.
