I’ll admit I am new to the whole AR15 thing and don’t have that many rounds downrange, but one thing I thought was a strange characteristic my new Stag Model 3 was the BOING from the recoil spring. I don’t have any problem with the sound but it does remind me a bit of the spring loaded Daisy rifle I once owned.
So as I am assembling rifle #2 and following The AR15 Complete Assembly Guide (great book) they suggested greasing the recoil spring and tube. I did and not too surprisingly the boing is completely gone. The $750 A2 feels like a well-engineered machine next to my $1500 Stag. Lubed up the Stag and it is now boing free as well. Night and day difference. Mind you I am not filling the tube with grease. Probably using less than a teaspoon. Apply liberally around the buffer then a film along the length of the sping. Book suggests Tetra grease but I am big into Slide-Glide from BrianEnos.com. I use Slide-Glide on all my M&P pistols and it not only makes the slide feel like it is on Teflon runners it absolutely does not migrate. The non-migration characteristic is what gave me the confidence to use it on the AR’s. If it does not run from the slide rails to the plastic frame after a 400 round session it should stay in the AR buffer tube. So is this common knowledge? Why does Stag not grease the spring? I can understand it being an issue in the desert but for where I travel it seems to be a no-brainer. |

I've seen a greased buffer assembly ran with dirty Russian ammo gum up to near uselessness.
Light coat of oil ok, much more then that is just excessive. Mine is damn near dry. Learn to love the sprong sound. Old gunshop rumors persist of greasing the buffer too much it hydro locks during cycling and blows the back of the buffer tube off. |
