Boot_Scraper Posted October 30, 2018 Report Share Posted October 30, 2018 (edited) I've combed over the "other" sights, too much static. What's y'all's opinion on "bedding" the barrel extension into the reciever with Loctite compound and it's varieties? Am I "using quotation mark"s correctly?

edgecrusher Posted October 30, 2018 Report Share Posted October 30, 2018 “Eh”, not needed normally. Maybe more trouble than it’s worth and cause headaches down the road. I can’t remember do you have a barrel already? How does it fit in the extension now? Quote Link to comment Share on other sites More sharing options...
Boot_Scraper Posted October 30, 2018 Author Report Share Posted October 30, 2018 The Faxon I have fits like a glove into the Xanthos upper. I had put some Locite on it when i had it in the PA10 upper and it was a little bit of a pain to remove. It did shoot well though. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted October 30, 2018 Report Share Posted October 30, 2018 Loc-Tite 609 is what you're after, for this task. That's the one. It's description makes perfect sense, too. On the Grendel Forum, they advocate it on every barrel installation, as well as truing the upper receiver face. I've never done it, on any of them. Don't know if my accuracy would increase or not, but it's never been an issue, so I just haven't invested in the 609 or the receiver lapping tools.

Matt.Cross Posted October 30, 2018 Report Share Posted October 30, 2018 If it's a good fit at present, don't fix what isn't broken. Quote Link to comment Share on other sites More sharing options...
HotRod308 Posted October 30, 2018 Report Share Posted October 30, 2018 I used low grade loctight. a light coating on the inside of the upper mating surface and light coating on the barrel extension. Insert, wipe of any that oozes out and apply torque, remember to wipe out inside of the upper as well. The reasoning I did it, is the same reason is why we glass bed bolt action rifles. We want zero zero tolerance fit, but not a press fit. Although the barrel nut tightens shoulder to the face of the upper, it doesn't remove the slip fit into the upper. The loctight fills the void and makes it solid fit. No chance of any movement at all. Yeah taken it apart later on can be a pain but a little heat does the trick DO NOT USE HIGH STRENGTH LOCTIGHT that requires near blow torch temps like red HOT glow to melt that high stength loctight. You only use that RED stuff on someones rifle that you don't like and will never see again. JUST KIDDING> Quote Link to comment Share on other sites More sharing options...

jtallen83 Posted October 30, 2018 Report Share Posted October 30, 2018 @Boot_Scraper 609 is the schit to use for sure, never had any issue pulling the barrel back off, cleaned up fairly easy. http://www.loctite.com.au/3320_AUE_HTML.htm?nodeid=8802648195073 Quote Link to comment Share on other sites More sharing options...

308kiwi Posted October 31, 2018 Report Share Posted October 31, 2018 Handy hint, Acetone dissolves loctite, takes a bit longer than heat but if you can't heat the parts up without compromising them then it works a treat. Quote Link to comment Share on other sites More sharing options...
HotRod308 Posted October 31, 2018 Report Share Posted October 31, 2018 You must use full strength Acetone then. I always grabbed my wife's finger nail polish remover as it had acetone 10% by volume and it wasn't hard on gunstock finish unless it was paint. Got a test before you go hog wild. Never thought of locthight 609, another good tip. Quote Link to comment Share on other sites More sharing options...

Most nail polish removers nowadays don't contain any acetone or very little. like you say, 10%. It also takes time to wick into the threads and soften up the loctite and it evaporates very quickly so you have to keep applying it. but it is the best alternative to heat that I have found.

survivalshop Posted November 1, 2018 Report Share Posted November 1, 2018 I use a Retaining compound on any new Build or Barrel install . My 25-45 Sharps has the Retaining compound & its a great grouping Rifle . Here is a Video of Criterion explaining what & why its used .

98Z5V Posted November 2, 2018 Report Share Posted November 2, 2018 ^^^ Loc-Tite 609... I need to buy some 5.56 and .308 lapping tools, and run before and after tests on some guns. I've never been unhappy with my accuracy, without doing any of this. But I need to try one (really accurate gun) and see what it does for it. I'm thinking the Mk12 Mod 1 5.56 gun.

I have had some that showed a very even face from the start, doubt they got anything from it. Others, like two DPMS uppers, were way out of whack, took forever to even get shine all the way around the extension face. Quote Link to comment Share on other sites More sharing options...
HotRod308 Posted November 3, 2018 Report Share Posted November 3, 2018 Its just one item to do out of a list of things to do to get all the accuracy possible out either platform regardless of caliber being fired. Quality of barrel, match grade bullets and components, A BCG that unlocks cleanly and consistently each time and well lubricated. Tight fitting upper to lower fit., nice crisp trigger, excellent scope. But just adding loctight without half of the other stuff or none of it, might not see any difference at all. I would be curious if others would rate what items would give bigger improvement over others. Adding loctight is like following a procedure, it just makes sense to me, is it measurable, good question. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted November 3, 2018 Report Share Posted November 3, 2018 The Barrel & Upper Receiver are really the Heart of the Rifles potential accuracy , they have to be as one for consistency & yes there are a list of things or components /parts that have to come together for superior accuracy , but it really boils down to the nut behind the Trigger, if all else is up to the task .

guruofhotrod Posted November 7, 2018 Report Share Posted November 7, 2018 On the subject of Loctite 609 - they also have #620, same strength but, it's made to fill larger gaps in the event you have a loose fit you need to tighten up Quote Link to comment Share on other sites More sharing options...

Alan Waters Posted November 13, 2018 Report Share Posted November 13, 2018 I have used both 620 and 680 to secure compensators to 38 Supers and .45's You have to bake the barrel at about 500f to break it down. Even then its a job for a wrench and barrel vise to unscrew. Quote Link to comment Share on other sites More sharing options...

It started in the firearms industry, through AAC, for securing supressor-host muzzle devices. AAC would include a very small applicator tube of it with every muzzle device they sold. Once they started doing that, the rest of the firearms industry started paying attention. Kevin Brittingham is a genius. Still is, always will be.
