  1. Straights Nuts
    No issues during install. Alignment holes all checked out straight prior to assembly and were oversized enough to compensate for the off center hole in the barrel.

  2. Good Gas Block
    I purchased this smaller gas block to to hide under a free-float hand guard. It works just fine. It was little tricky to get the roll pin started due to it being round and all. Next time I'll be looking for (or making) something to hold the gas block in place.

    To install I marked a line from the middle of the holes on the barrel and the gas block with a pencil and lined them up.

  3. Cost effective gas block!
    Purchased this little guy for an 11.5" lightweight build. Gas block has performed perfectly over in over 1400 rounds of use. Great block for the price.
