Well, as long as you asked...
Iirr, the poppet failure on all variants of the avenger series is still a problem, and poppets at least in the past, were not in stock. other than from custom shops making custom poppets, if you can even source one of those easily.
To me thats the determining factor. As having a cheap good rifle that no longer works, without parts to fix it, isn't really a savings. Maybe others that know more about these rifles will chime in on the poppet problem and tell us if it is fixed yet...?
Mrod 5 year warranty from NY. Warranty is very easy to use. With most all parts readily available, if out of the 5 year warranty. Made in America, warranty in America, made by Americans... Regulators on Mrod are not needed unless you are a competition shooter, and even then maybe not. Search forum for,, reg creep, reg problems, reg leaks, etc. Sometimes less is more...
But the Avenger has a side lever, a regulator, 1 year warranty(maybe..?), lightweight cheesy stock, and shoots very well, until it doesn't...
Lots of happy owners of both.
Your choice
