300 Whisper SBR AR

[gotgraham]

Hello all. My name is Jacob. I'm new to the forums, but have been playing around with 300 whisper for the last year or so.

Just about done with my SBR 300 whisper AR-15. It’s turning out nicely I think.

- 8.5" Krieger heavy barrel
- Pistol length gas system
- CMMG SBR registered lower
- Rock River upper
- DMPS hard chromed bolt
- Magpul MIAD grip
- Magpul CTR collapsible stock
- Troy Industries front and rear iron sights
- JP Mid-length handguard
- Gemtech HVT Quick Detach flash hider.

Waiting on Form 4 approval:
- Gemtech HVT .30 cal suppressor, quick detach

Looks great! I'm thinking about building similar upper after first of the year. Where did you get your barrel? Also, did you use a adjustable gas block?

Thanks! I got the barrel from a friend of mine - don't know where he got it. It was originally 16" with a pistol length gas system. I had it cut down to 8.5". No adjustable gas block yet. I had pretty good luck with this gas system on the longer barrel; hopefully it still cycles well :).

That is an excellent setup you have there.

Let us know how the Gemtech works -

That looks great. Almost exactly how I want mine to be set up.

What twist is the barrel and what do you plan on shooting through it ?

It's a 1-8" twist barrel. I am current shooting 190gr prvi projectiles through it. It seems to be a pretty decent package.

Is that a pistol gas setup?

I got my Gemtech HVT! It was approved on the 10th and I picked it up form the dealer today. Can't wait to try it out...

Nice looking set up! Let us know how it shoots and how it sounds.

Very nice. Please let us know how that HVT works out. I'm waiting on one myself.
