I doubt it would make it any heavier than my NM AR. I have an extra 6lbs added to itI bet it makes the rifle heavy.
Bingo-- I think their stuff "looks" great-- but would not put it on a gun I intended to shoot-- heard the same thing you did. No proof from me actually seeng it, but think that at least the hanguards would be fragile...ironwood desgns has been around a while. they garnered a lot of bad rep by screwing a couple guys on arfcom after their original wood stocks split after less than one full magazine of use. yes it looks neat for a wall hanger but in real world use it wouldnt last.
It's funny... there are 2 types of people. Plastic gun guys, and wood gun guys. I have a few AR's, and hate them. They shoot where I point them, but I would pick up my Garand, or a K31 first. The plastic is too "impersonal" to me. I think the walnut makes it look, and feel like a FAL, and what the original M16 should have been if molded plastic wasn't to damn cheap.thats just wrong.
