I decided to sell my baby. Her are the specs:

Upper Receiver:
JP CTR-02 Upper Assembly Machined from 7075 T6 billet
Barrel: JP Supermatch™ air-gauged, button-rifled, cryogenically treated...

I have one on a 16" midlength with a regular carbine spring. Works fine. No noticeable difference from a regular buffer.

I've used my Matech sight on my Grendel out to 550 yards. Although it is calibrated for 5.56, it works reasonably well with the Grendel.

The Burris mounts are made in China, but are rock solid and well made. I own a P.E.P.R. and a set of their 30mm rings. I saw the Burris QD P.E.P.R. at the SHOT show. Cosmetically, they are not up...

Out of curiosity, I did some searches on this. There is a great info page at http://bobshellsblog.blogspot.com/2008/07/blank-ammo.html

Apparently CH Tool and Die Company sells the dies to make...

I've had a Horus scope fall apart on me - literally. An internal lens in front of the reticle literally fell out of position and was rattling inside the scope. Luckily this happened at the range,...

I'm going to agree with glane5910 that it appears a gas issue. Check the gas block alignment to the gas port. If you remove the gas block, you should see a carbon stain on the barrel (at least on...

$50 plus shipping.

For what it's worth, I tried the Badger Ordnance Tac Latch on my charging handle. It's great on the range, but if you have to carry your rifle for any period of time, anything protruding towards your...

I spoke to the rep at the Shot Show in January. It has a burn rate similar to Varget. That makes it a little slow for the Grendel.

I would guess that it's a simple 7.62x39 necked down to 6.5. If they use the Grendel case, they probably wouldn't be able to feed out of an AK mag due to the difference in case taper. It looks like...

+1 for the Wilson case gauge. Great for setting headspace of your dies, doing QA on loaded rounds and checking trim length. I have one for every auto-loader. With bolt rifles, you have a lot more...

I shot a similar size hog about 3 weeks ago with a Barnes 120gr TTSX. Similar results - it didn't move at all. It just rolled over.

I used to preload but found it didn't make any noticeable difference. Having one less thing to think about helps me concentrate on other elements of my technique.

The other thing you may want to look into is the extractor thickness. I had an AA extractor that was too thick. When the bolt was pushing a round forward and the extractor was over the rim, there...

500m (550 yards) on steel silhouettes has been the longest so far. Accuracy is not a problem, but the Grendel fails to have enough kinetic energy to knock over the heavy steel ram silhouettes at...

Awesome. Glad to hear that worked for you. I went through months of pain and suffering trying to figure this one out. I event sent it back to the manufacturer who returned it unfixed. After I...

Visually, this looks exactly the same as the problem I had with my first Grendel. After a lot of experimentation, I found out that the ejector pin was too long. As the round was being put in the...

Well, we got back from the hunt. I shot a 120lb boar. Just like last time, it was "bang, flop, dead". The 120gr Barnes TTSX penetrated behind the right shoulder, expanded, and passed clear out of...

I have a 16" AA Tactical Upper. Accuracy is about 2-3MOA which is acceptable for hunting. I chronographed some loads out of it this Wednesday using an Oehler chronograph.

My hunting load is...
