Lightweight Build for Stalk hunts

[BjornF16]

Finished the build today. Here are the first pics. She weighs in at just under 7 lbs (without scope, no rounds in magazine). Hope to test fire tomorrow. Will post a range report then. Thanks for all y'alls help!

If you want to cut more weight, get a PRI adjustable, low-pro gas block, versus the one you have. If that's a steel JP, they are quite heavy. If that's an Aluminum JP, you need to take it off anyway-they will leak on carbine or mid-length gas systems. Trust me...

[BjornF16]

Steel...I had originally planned on the aluminum but I heeded your advice and went with steel. It weighs 6 oz.

I cut down one of those JP adjustables because it was just too heavy, so I made lightening cuts in both sides, cut the front down, removing one clamping screw area, and angled the front of it. I melted it down with an Aluminum oxide-impregnated buffer pad, blasted it, and Cerakoted it. It's still heavy, but about as light as it will get. I don't think I have a use for it really. It weighs 3.2 ounces now. My low-pro gas blocks weigh 1.3 ounces. I doubt the PRI weighs much more than that.

I had a false start this am (LaRue mount wasn't tight enough...my fault) but I got a start on breaking in.

This afternoon was really hot; 102F with a slight crossing breeze...but I really wanted to shoot after resolving the mount issue.

I took two new sighting shots, then loaded 5 for paper. I ended up shooting 6 since I had a flyer (#4, most likely a flinch). I've never shot in this kind of heat, so not sure what the effects of rapidly warming barrel will have.

I adjusted the gas block at 1.5 turns from fully closed. This resulted in brass landing at 4 o'clock between 6-10 feet away. Examining the necks I saw no "denting" like I get with my factory Grendel Entry upper (non-adjustable gas block).

As I shot more (didn't really wait long between shots; cleaned after every 5 or 6 for break in), the accuracy became worse. The wind started kicking up more as well. I'll go early next Saturday and see if cooler weather makes a difference.

Nice stick! It looks good. Don't worry about the accuracy, just keep tinkering, you'll get it.

BTW, the WCI brake was awesome! A real pleasure to shoot...looking forward to cooler weekends and CO in November.

Hey, also make sure you are hydrated and lay off the coffee, get enough rest as well.

I am sure you know this but make really sure your gas block is not contacting the bag

Steel...I had originally planned on the aluminum but I heeded your advice and went with steel. It weighs 6 oz.

If you want one in Ti, let me know, I may be running a batch once I get time to run mine.

[BjornF16]

Adjustable?

[warped]

Yep, it will be about 30 days until I can get mine done, test and be ready to run a batch.

[BjornF16]

What sort of design?...low profile? railed?

Unfortunately, I'd have to add 8.25% sales tax...
