Hey! My 300-221 AR Upper Arrived!

[Fudmottin]

And it looks good! The whole rifle (sans optic) is lighter with the 300-221 upper on than my 223 varmint upper with 24" x 0.930" barrel. I can see why you guys like SBRs now. They must be right handy. Although compared to what I'm used to in an AR, this package feels like a brush gun.

The only minor hitch is the take down pin fit. The rear pin is very tight. I'm guessing this is due to slop in DPMS' tolerances. Both uppers have the DPMS A3 style upper for the A-15 lower. The 223 one is a breeze to pop on and off. Hopefully the pin holes on the 300-221 upper will wear in so I don't have to ream out the rear one.

Now I just need to load some rounds and take it to the range. I'm going to be mounting the same optic as the 223. I bought it before I noticed some limitations in the range finder. I'm going to have to give the Burris 4-12x42 Laser Scope only a B.

This thread would be worthless without pix:

Since the pictures were taken, I shifted the scope forward to improve eye relief. I also get better access to the charging handle.

The scope seems ridiculously large on the whisper upper. But who cares what it looks like so long as it shoots, right?

Very nice- I am sure you will be having fun :)

[Fudmottin]

I think so to.

Doesn't that barrel just scream out for a reflex can? A can that makes it just back to the hand guard would give me the SRB look. I would be lying if I said that SRBs don't look cool. I just don't like the baggage that comes with them.

Do you like that scope?
Any video off of it?

[Fudmottin]

I mostly like it. I was loving the repeatable range finding ability. Not so hot about the lower portion of the reticle (I opted for the mil-dot as backup to the range finder). I also got a rude surprise at the range when it stopped finding the range for me in sunlight at about 200 meters. I'm hoping it is just due to a low battery and the fact that it was 31F at the time.

If you don't mind the politically incorrect, you can watch a video I put up on YouTube where the camera is looking through the scope:

It does have a yard mode. I just prefer meters. There was no magazine in the rifle at the time of recording. But someone looking at my window would probably have been most annoyed.
