Upgrading to steel from aluminum is a worthwhile investment considering this part essentially holds the whole gun together, solid construction and honestly the added weight of this compared to the aluminum is not noticeable at all
Don't know if it was necessary weight is not an issue just building a deer hunting rig 22 cal not leagal where I hunt I'm thinking the wolverine will work out fine
1018 Steel Barrel Nut - AR15/M4
I ordered the steel barrel nut because i felt it would be more secure than the aluminum one that comes with the rail. Although a bit heavier than the aluminum nut, it felt more substantial and gave me a greater sense of security that my rig was solid. My only complaint is I wish the rails just came with the steel barrel net from the get go.
