I am looking at an AR15 for varmints at longer ranges.
I want the flat-top and long, free-floating handguards.

The hard decision......20 or 24 inch barrel length ??????

This gun won't be carried very far, it will be shot from a bench or prone on the ground.
Will the 24" barrel give me any extra range ?? It "should" have a bit higher velocity.

I am not sure how the balance will change, as I do not have any near me to try out.

Thanks
Good Shootin!!

I just bought my first two-footer. I figger the extra four inches will translate into extra velocity; crosswind is the bane of the 5.56.

I had a Bushmaster Varmiter with a 24 inch barrel and I did not like it. It was to long and akward. I got rid of it for somthing with a 20 inch and I like it much better. On the other hand if you are just going to put it in one spot and keep it there then the akwardness may not bother you. You will enjoy about 100 to 150 fps more with the 4 inches.

I love my 24" Bushmaster H-bar... It's just the plain fact no one else likes it.

It was only $10 more than the Bushmaster 20" H-Bar. So I figure why not? It's worth an extra 100-200 fps, but nothing to write home about.

Other than the fact I have the right to call it a BFAR15

Count me in as a fan of the 24" AR. For what you described, the 24" is the way to go IMO.

Here's the exact 20" varmint upper I purchased from White Oak Armament (including spiral fluting):



20" bull barrel
1-7 twist rate
Wylde chamber
Complete bolt carrier group included

I've added a LaRue SPR scope mount, Leupold VXIII 4.5x14x50 scope and a Harris "L" bipod to the upper.

I'm very pleased. The varmints will not be...

i like the spiral fluting... it just looks cool. i would go for the 20' barrel with the bullets your going to be using for varminting, i dont think the extra 150 fps is really that much of an advantage.

A good quality 20" barrel is all you need.

The barrel's got spiral fluting under the handguard too.

The upper is heavy enough just being 20". 24" would really be too much, I think...

24" barrel.

I've heard positive comments about using 45gr HP Varmint rounds from Winchester in 1 in 9 twist barrels yielding sub-MOA accuracy... I bought a few boxes to try but the weather has not been permissive.

I have a Bushy 20" and the 24" fluted, I only notice the difference at long distances where the 24" is a more consistant shot.

Why not get the 24"? If you decide you don't like it you can always have it shortned, but I've yet to see anyone advertise a (legitimate) service that lengthens a 20 to a 24 incher.

I would be sure to get it in the Wylde chamber and to look into fluting if you're serious about varminting: you want the accuracy of the tighter chamber and the fluting can help with barrel cooling since it gets plenty hot out there as you're blasting pups.

Depending on the fluting, you might not be able to lop four inches off the barrel. Then again, people do pretty creative things with lathes (just ask Mongo).

I'm sure the boys at ADCO can shorten barrels without any problems. Just costs money!!

Will 77gr or 75 gr ammo perform well thru a 24" 1/9 stainless barrel ?

I use a Colt HBAR Elite (6724) w/24" barrel for shooting prairie dogs
