I cut my mossy 500 down to 19 inches. I was going to do it long just in case. But it came out so nice I just left it. Why not give it a try since it is a cheap gun? Just leave yourself a little extra in case you booger it up. I used a dremel with a cut off wheel. I then used some really fine wet sand paper on the end. I needed to reblue the whole thing anyway.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
