The 13.5 left hand to ½x28 is the ½x28 right hand? or is it left hand? Expert Answer

The Kaw Valley Precision Thread Adapter 13.5x1 LH to 1/2x28 converts a 13.5 (LH) threaded barrel to a 1/2x28 (RH) barrel.

Looking for torque specs on this item and is threadlocker advised?

Not sure your application, but as a guide the AR-15 family says 24 ft-lb for muzzle devices, I would start around there. Crush washers are used for things that need to be timed, like a muzzle break, but not needed for things that don't have a specific orientation. Thread locker on a muzzle device is almost a holy war. If you use a suppressor, then yes definitely use thread locker, with no crush washer (they make timing shims for this application instead) and Rocksett is the recommended one there. If not, then the standard on an AR-15 is to use lubrication (believe it or not), Areoshell 64/33MS grease is the TDP recommendation.

Kaw Valley Thread Adapter by Boomhaur, Verified Owner, April 13, 2024
This is just what I needed to adapt a suppressor to my AR9, barrel thread 1/2x36 to 5/8x24. Worked great for my QD muzzle device. Highly recommend!

AK-47 muzzle device thread adapter 14:1mm to 5/8” by Arsaregood, Verified Owner, February 14, 2026
I ordered just one of these because the picture advertising it shows it to be a big unsightly looking adapter, but after I received it I verified that picture is not the actual reducer. The one you will get is a lot more streamline like the other pho...

Great adapter by Will, Verified Owner, September 25, 2025
Kaw Valley continues to impress me with their high quality, low cost products. I bought a 7.5 inch 9mm upper without realizing that it was threaded in 1/2x36 instead of the more common 1/2x24 which I needed to mount my suppressor (Yankee Hill R9) tha...

Great adapter! by Danny482, Verified Owner, July 24, 2025
Needed this little jewel to attach my new can to my .45PCC. It came with some oddball threads. Thanks to Kaw Valley it works now.

Fit and finish okay sort of smooth by DaveTXK, Verified Owner, July 23, 2025
Threading on is a very fine thing - initial thread probably not perfect, but did go on easily after I got it started - no burrs noted completely tightening it down. Have shot with it on once and it did not back out (no crush washer used - no timing ...

Product Info for Kaw Valley Precision Thread Adapter

Bring new life to a firearm that may not sport a common muzzle thread. KVP thread adapters are the best choice for converting your current barrel thread to a standard thread. Allow yourself the flexibility to attach your favorite muzzle device/suppressor, to multiple weapon platforms! Our adapters covert BARREL thread pitches"to" desired MUZZLE device thread pitchs. For example, 1/2x28 (barrel thread) to 1/2x36 (muzzle device/suppressor thread), converts a barrel threaded 1/2x28 to 1/2x36 for installation of corresponding muzzle devices or suppressors.NOTE: ADPT-1311 (.578x28 to 5/8x24) can be used in .45 ACP applications!image
