870 mag tube extension, drill or grind?
« on: December 31, 2016, 02:19:07 AM »
So I picked up a couple of LEO 870 exp magnum trade-ins a while back and going to add a +2 extension.   The tubes have the indents/dimples, so what are all the cool kids doing, drilling or grinding?

    Drill it. It will leave burrs that will need to be removed so it will end up as a combination of drill, grind, and buff...but in the end you'll have perfect function.

    Thanks doc, was hoping you'd weigh in.  That's the way I was leaning.  Drilling and deburring seemed a bit cleaner just wasn't sure if there was anything to consider due to putting holes in the tube.  The barrel covers them up so wouldn't think there'd be a problem

    Thanks!

    It will take a little longer than you'd expect to dremil the inside. You have to remove all of the dent. Don't short cut it and make the drilled holes any bigger than absolutely necessary. It's just your guide. Do the rest from the inside and then polish it.

    so here is one of them, going to be the truck gun.  took like 20min last night and no issues, thanks for the advice.

    I put a XS bead sight on it (not shown) and a NcStar 6x side saddle.  Had to put in new trigger group pins because the side saddle it came with was attached with the trigger group bolts.  went with the MesaTactical anti-walk pins only because they were cheaper than the stock pins.  No real opinion on them except now i have to have a couple allen wrenches to break it down. Probably won't go that route with the other one.  I was really torn dumping the wood furniture, but the stock had a cheek riser on it that made it difficult to get down on the bead sight.  I also wanted to shorten it a bit and couldn't bring myself to cut up the wood stock.  So i went with the magpul stock because i had one on my turkey shootin' gun and really liked the ergo.  Went with the stealth gray because my therapist said it would have a calming effect.  She was right, i feel better already.

    Looked almost identical to this one, except for the rifle barrel.  This is going to get a +3 and the NcStar 6x saddle, going to leave those nice old beat up stocks alone.

    you can get cheap OEM furniture from Numrich. I got a stock from them for $14 once. bits an bobs, recoil plates, Ect. for $3-8. shipping is long. but with prices like that? I can wait.

    Yeah, you'd think so anyway. I checked them and I think Midway was actually cheaper (not by much though).  I think the Mesa pins were like $10 for both and OEM pins were like $5-8 ea.  Not a big deal, just thought I'd save a few $.
