RRA A4 Varmint with a Nikon Buckmaster scope

After reloading a few 50gr VMax bullets with a middle of the road load out of the first reloading manual I picked off the shelf, using some some 1X fired range pickup brass.

After I sighted it in, I shot this 5 shot group.

.520" at 100 yds.

I have a feeling this one is gonna be a fun rifle.

Thats great accuracy for any rifle but help me out. Isn't the A4 a non free float upper.

With my RRA M4 I only get 2 to 2&1/2 @ 100 but my 24" free float bushmaster upper shoots like yours.

The A4 Varmint is the flat top free float.

They most commonly have a 20" SS bullish barrel. but you can get a 24" IIRC.

I was very pleased to say the least with the results of my load without really trying.

Thanks I realized after I made my post that you said A4 varmint and not just A4.

I'm looking for a shorter varmit type upper that shoots like yours. My 24" is just to long and muzzel heavy. I'll have to check out the A4 varmint. Thanks.
