  1. Nice fit and finish
    Very nice finish and tight fit to my NEA barrel. I recieved mine with an exrra set of adjustment screw and a roll pin that was a very tight fit (it required a little squeeze with a pair or pliers on the very end to get started). I have not fired the rifle with the new gas block yet but its a simple piece and doubt it will give any issues. Thanks for super fast shipping too

  2. Careful!
    Make sure you release the locking screw before adjusting the set screw. I stripped my set screw making the entire gas block useless. The screws are very soft metal and super easy to strip. Nothing wrong with the product just be careful. Only thing I could suggest is that they use a better steel screw.

TNA Elite Series Adjustable Gas Block

In stock
SKU
TNA Elite Series Adjustable Gas Block
From CA$70.31

True North Arms is pleased to offer these finely manufactured adjustable gas blocks.

The adjustment is done from the side -- a set screw obstructs the flow of gas. Most handguards will let you do this through a slot (or if not, a drill fixes that). Another set screw accessible from the front (muzzle end) will lock the adjustment in place.

You get:

  • (1) Gas block
  • (1) Gas tube roll pin
  • (1) 1.5mm hex key

Installation Difficulty: 

Tools required: A 5/64" pin punch to get the gas tube roll pin installed.

Installation tips: You need to watch that you don't cover the gas port and thus have the block rotated correctly. Just take your time.
