I thought I would post this because a few people don't like the JR Carbine's original rail. As well some people, including myself are unsure of which forends will fit without modification.
I purchased a Yankee Hill Machine forearm that included it's own barrel nut and "anti-rotation" screws.
I had no issues putting it on and after bringing out the verniers calipers noted that the measurements between the two were very close.
So no spacers needed as I've heard when going to a new forearm on these guns.
I'm going to experiment with different rail covers. I kinda like just the plain Magpul ladder rails, which I have on
the bottom of this forearm.
Here's some pics.
