Gunsmithing Recoil lug?

Re: Recoil lug?
I had one installed on my 6.5x47 Lapua and ended up regretting it. Not only does it add unnecessary weight, it did not allow my barreled action to fit into the new AICS stock I purchased.
I say don't do it.

Re: Recoil lug?
Hi you dont need an oversize recoil lug but if you have the action trued and accurised you should at leasy have the rem lug surface ground or replace the lug with an aftermarket lug that is ground to make sure it is square. If conventionaly bedding the rifle not using a drop in stock their is not much of a downside using a thicker lug, we use Lawton lugs on nearly all of our rifle builds as some rem lugs will crack with a heavy recoiling rifle but this is not the case here, so have the factory lug surface ground or fit a replacement the similar size or get the larger lug dont use the factory lug as is if putting all of the effort and money into a precision build.

Re: Recoil lug?
you can get precision ground recoil lugs from Midway in different thicknesses. McMillan stocks seem to have recoil lug recesses that will take .250" lugs, the old AICS stocks would take .196"
the main thing is to get a flat/true lug. your factory lug can be surface ground.

Re: Recoil lug?
Looking purely at physics, there is no real advantage to going thicker than .250". In addition, the thicker lugs are typically bedded in a material weaker than the lug anyway, so the sacrificial component becomes the bedding material. I've surface ground and re-used numerous factory lugs on the SPS Tacticals and it's a huge improvement. Do I recommend a lug thicker than the factory Remington? Yes. Do you benefit from a mondo thick lug greater than .250"? No.

Re: Recoil lug?
The factory lug allows a bit more flex than harder lugs and it's usually not flat.

I have a hard time getting my mind wrapped around the idea that my shoulder can produce a solid enough backstop to flex a factory recoil lug on any caliber.
I have no doubt they are not flat.

Re: Recoil lug?
I've wondered the same, good questions.
So if someday I change my barrel out and change the lug, that would obviously mean re-bedding the action, correct?

Then you should probably use the factory lug.

If I'm wrong then please explain it to me. Have you seen examples of lugs breaking from recoil when everything else was tight?
How would you determine if a lug is flexing?

Re: Recoil lug?
if you have the rem lug surface ground it will be a lot better than the factory lug, the rem lugs are stamped where the aftermarket lugs are machined. this makes a huge difgerence. yes the rem lugs flex how would i have some that have cracked at the junction of the ring and lug? that is on large magnums though and you wont have that issue. Have a look around you can get a replacement lug that is machined and the same profile as the rem lubg but because they are machined from stronger material they are a better option.
I think we have given you an answer you were not looking for but now it has been explained trust the people you have asked and replace it or at least have it surface ground the 6.5X47 does not have a huge recoil force but any rifle benifites from a square recoil lug.

Re: Recoil lug?
I don't see a downside to either one, aftermarket lug or a surface ground factory lug. That said, I'd probably just go with the thicker lug for any possible advantage it may give just so I don't wonder later on if it was a good decision. In my mind, the subtle difference in thickness wouldn't make a quantifiable difference as long as it is flat and true.

I agree 100%. If your not going to grind the factory lug get an after market lug from PTG. I'd get one of their .250" thick lugs, either the Remington style or the Tapered style. The CM lugs are heat treated and surface ground. They are extremely flat and of high quality.

Re: Recoil lug?
The after market lugs have a little more surface area to contact with the bedding also.
