I used to have an AR, but it was a 20" heavy barrel with a rifle length rail. Long story short, it heavy. Too heavy for me, so I got rid of it. Now i'm looking at getting another one to work on my marksmanship, since I plan on enlisting in the marines after I get out of school. My question is, Is there a good A4 style 20" rifle under $800? I'd like the opportunity to use the iron sights, but it would be nice to be able to put a scope/red dot on it later down the road. If there isn't, what kind of difference is there in the ballistics in 18 vs 20 inch? CMMG has the 18" govt. profile rifle in the bargain bin for $600, and I think it would work good enough for my needs. Any help would much appreciated, thanks.

How about a lighter weight M4 profile, 16". Check out the Stag 3H I believe it is.

People keep saying CMMG 18" Bargain Bin, but I'm looking at their site right now and it's a 16" M4, not 18" G-barrel.

And also, in answer to your Q about 18" vs. 20", here's a chart regarding FPS and different barrel lengths. 4th post down.

The CMMG 18" sounds like the best your going to get in your price range, and its a fine gun.

Having a rifle length gas system on an 18" barrel means it won't like weak ammo like Wolf. May short stroke. So keep that in mind if the gun chokes on plinking ammo. Good mil spec or better 5.56 should be fine.....I think.
