Check out the Stag LPK or Grant's. Either one should be GTG.

Thanks, Col Crocs. I checked both manufacturer's out. It appears they both come with a standard grip and trigger.

Has anybody had any experience with White Oak Armament LPK's? I read somewhere that you can order triggerless LPK's from them.

Hmmmm Did you select the options in the drop down for the LPK on GRTactical? You can order JUST the lower parts without a trigger/hammer etc... Order exactly what you want:

That seems like the best way to go since you have the trigger.

[jatienza]

Thanks for the heads up. Fortunately, I have not ordered the LPK yet. Your suggestion should save me a few dollars.

with as much as you are spending on the rest, what's a few bucks?

i kid, i kid. nice build. post pics when it's done.

Should be a great rifle. Have you run Ergo grips in the past? Reason I ask is that I have seen more than a few break. Consider the Magpul MIAD? It gives you the most options and should allow you to put the trigger exactly where you want it.

I have an Ergo grip on my ArmaLite and have never had a problem with it. I like the feel of the grip.

I hear ya on the cost. I am in for $4,600 so far.

Should be a great build. I have a Stealth 18"/13.2 that will be here Wed/Thur, I am doing a similar build on a new 6920 lower. I am torn over the UBR and will probably go 32mm on the NF, KAC on the BUIS and with the MIAD. I am looking hard at the ACS... I am also going to go BoBro on the bi pod instead of the Harris...

What are your thoughts behind the your choice of sling on a SPR?

Sounds like you have the LPK handled, I will be looking forward to some pics and a range report....
