Hello everyone! I need some help! Ok, so here's the scoop. I'm assembling a ar15 for my girlfriend. She loves shooting mine, its a 18in intermittent length odin works 3 gun SS .223wylde barrel with a free float barrel, Geissele SSA trigger etc. We usually go to a range that has targets out to 800yds. And she can hit the 800 fairly well, not Navy Seal Delta Force Ranger but she can hit the 12in target 3/5 times using my rifle. Hopefully better when I finish this rifle for her. Our Anniversary was October 28th, which I assembled her a Lower, Anderson Lower w/ basic LPK. Geissele SSA Trigger, Magpul Miad grip, Magpul enhanced trigger guard, Magpul CTR and Noveske QD end plate. Her Birthday is coming up (November 21st) and I am currently working on her upper. Time is running out and I have no decided between 2 barrels. I want her to have the range and accuracy of my 18in Odin Works barrel but I also want her to have a lighter and shorter barrel, which is why I was looking at the Odin Works 223Wylde 16.1in Midlength barrel. Odin Works 18in 223wylde Intermittent Length 3-Gun SS Barrel 1/8twist https://www.odinworks.com/223_Wylde_Barrel_p/b-223-18-3g-int.htm Odin Works 16.1in 223wylde Midlength SS Barrel 1/8twist https://www.odinworks.com/223_Wylde_16_1_Mid_Length_p/b-223-16-ml.htm We will be shooting at up to 800yd a lot of the times. Using 77grain match grade ammo. The reason I was looking into the shorter and slightly lighter barrel is, I do not want the 18in to drag her down when I take her to a rifle class/course. What will the range and accuracy difference be between the 16.1 and the 18in Odin Barrels?
