What you guys think about J&T?

Grunt, given the choice between a Templar Customs or a LotharWalther, I would go Templar. Templars are cut barrels, while the LW's are button rifled.

Given the lapping tool that most use is only $35, it may be worth giving it a try. And many smiths only charge about the same to lap. But be careful, as if the lapping compound get's off the face and into the receiver to barrel extension area you will be increasing slop, not decreasing. IE: Don't lap the inside, just the face)

That said, the receivers you hear about that are noticeably off (several degrees) I'd worry about for other reasons. IE: If the forging and subsequent cleanup was that out of spec, then what else is wrong?

Likewise, some of the smith measuring tricks are only measuring variance of the face to the rail or other external parts of the receiver. When what matters is how perpendicular the inside of the receiver is.

And some smiths have reached a point that they use the lap tool as a gauge with feeler gauges. If the gap is over a certain amount, then it's the receiver that's out of spec. You can decide whether to lap or just get a different receiver.

Sometimes you hear about free float hand guards with barrel off center. Which many presume to be a barrel/receiver misalignment. But depending on how the handguard attaches, it's far more likely that the handguard is mounted incorrectly.

Remember how the receiver to barrel extension/barrel works. My observation is that in a good, in spec receiver more alignment comes from that "fit" than the flange & face. There may be something to be said about equalizing force between the barrel flange, etc. Potential impact on harmonics. But I've not seen any verifiable information on this pro or con.

You are using high end components. Which should be in spec. I would not accept a VLTOR or MEGA billet receiver that had to be lapped to get a perpendicular face. But if you want to be sure, the tool is cheap. I'd just get a read from your receiver mfg if that would in any way invalidate warranty.

But all of this is just my opinion based on what I've been able to research. And I'm not a smith or high end mfg. There are others on the forum who may have a better or at least different opinion on it's real world impact on accuracy.

Templar trued the face of Yut's Grendel, and re-coated it. Bob said it was some type of anodizing touch-up, which could be Duracoat for all I know. I also prefer the precision guns where I have to tap the barrel into the upper. I know at least one gunsmith who has beaded barrel extensions into uppers, and even unitized them on guys AR10's that wanted a certain accuracy guarantee. Not sure I would do that, but there is significant barrel whip in the AR15, and more in the Grendel.

I have only shot my Grendel through my MGI Quick Barrel Change upper, and achieved slightly less than MOA with a button-rifled barrel and Scenars. Maybe I will drop it in a dedicated upper some day and see if there is a difference.

Well its been a while and I have both my uppers at about the 1500 round count. I forgot to do a little report untill I got a PM the other day from a guy wanting to know how the precision firearms upper was shooting. At 100 I cant tell them apart. Both will shoot sub moa all day long. 1/2 moa if I'm on. To tell the truth they both might out shoot me. I have proven to be right about a 1/2 moa shooter with my bolt guns over the past 25 years. Now as you start to get out a ways you can start to see what the extra money bought. Now I dont really shot groups all that much and I dont really ever measure them but the precision upper is holding sub moa or right at it @300 while the JT is closer to 1.5 or 2 moa. I shoot steel most of the time and have had no problem's taking each gun out to 650 (650 is as far as I have went with them. My GAP 10 in 6.5 creedmoor handles anything longer =). But you can tell by the splater marks the precision is shooting tighter. So far I have had no problems with them at all just load up some mag's and shoot all day so all in all I happy with both uppers and my wife loves the JT she shot her first deer ever with it this year at a whooping 40 yards =) I know its a crappy report but oh well. =)

My only Grendel is a 20" J&T. So far it hasn't won any matches but it has killed several varmints and an Elk. I sure ain't complaining. However, I am looking at getting a barrel sometime soon and starting a new build.

Are you running FF or standard HG's? Pics.
