Maverick 88 Top Rail Drill and Tap

Drilling and Tapping a Maverick 88.

[@rpm2dayg648]

"I'm not a machinist." Well, you're doing a better impression of a machinist than many other so called machinists that I've met in my 30 year career as a tool and die maker. Thanks for the vid, I just picked up an 88. Great little shotgun.

[@ericmanseau2382]

Great tutorial. Thanks.

[@JonathanBaileyn2u]

Good prep and approach, imo! Ty for the video.

[@teknofiliak]

Thanks!

[@jbhickok7796]

Right on man. Now that was helpful, Going to do that to mine.

[@teknofiliak]

Post a video!

[@rico300zx]

Dude you are brave! Good job

[@teknofiliak]

Eh, it's a pretty cheap shotgun. Worst case scenario, I had a shotgun with misaligned holes on the top! :D

[@Balaclavaballistics]

Good work😊

[@davidmcgahan5328]

I am going to do this to my 88 good idea. Thanks for the video. Did you try it yet ?

[@sleazykilla360]

yeeaaa I'm just gonna send mine to a gun smith to do this. I don't trust myself and my OCD will not allow a slightly skewed rail lol.

[@williambotts635]

Wished mine were drilled, but no gunsmiths here and I don't have the tools. Keep up the videos on the 88, waiting for more.

[@baitball4665]

harbor freight. 10" drill press and cheap tapping kit for less than $150

[@lanapolishchuk9805]

How was your tapp bit marked and what size drill bit did you use? I'm hoping to tapp my Maverick 88, so I really need those specs! Thanks for a great video. God bless

[@teknofiliak]

Just saw this. 8-40 tap and #28 drill bit.

[@rokinrandy]

He mentions it in the video but still Best check the screws that you have. incase they may be different. And for anyone that hasn’t in a while. please practice using a tap and die set on some scrap before you start hacking away on anything that you plan on keeping.

[@user-ko5fh8wn3g]

I lost something here.. Great video and you did a hell of a good job. My question is, you measured and drilled and tapped for the Pic Rail and didn't use it at the end.. Did I miss something?

[@teknofiliak]

I literally just used the pic rail as a template for the holes. I initially bought it to use, but then found the direct mount for my Vortex dot, so I went that direction. The pic rail was like $7, so I figured I'd just use it as somewhat of a sacrificial template.

[@barrymatthews6358]

Hey question… where did you get your drill and tap bits from? And also the machinist tap handle?

[@teknofiliak]

There's a reply to another comment with that info.

[@barrymatthews6358]

I think you did a great job! You definitely helped me out? I’m gonna be pretty much doing the same thing! Thanks for the info!

[@teknofiliak]

You got it!

[@metralf]

​​@@teknofiliakThank you for this tutorial. Will do the same to mine. Did you use locktite to screws? Is it safe to drill closer to the barrel? I want to use 12cm long picatinny.

[@teknofiliak]

I used blue loctite. I wouldn't see why it wouldn't be safe, but do it at your own risk. I had the barrel pulled out when I did all this stuff.@@metralf

[@Ed1988_]

Great instructions. How is the $20 red dot holding up to the 12 gauge recoil?

[@teknofiliak]

Vortex isn't a $20 red dot.

[@Ed1988_]

@@teknofiliak , oh, $20 mount. My bad. Which model red dot are you using? How is it holding up?

[@CarlPapa88]

Hadn't even ordered my Maverick yet, but good tutorial. 👍 Thread the barrel for to accept a choke next. Idk how much it'd cost to have done, but I'd like to have the feature on the 20" Security model.

[@Barikade]

You can rent the items needed to thread the barrel yourself from Brownells

[@Barikade]

Lucky gunner has a video up on how to do it. And drill and tap for a mount👍🏽

[@rokinrandy]

Just one more question. I heard you say an 8-40 tap. Or was that a 1/8 40 tap. I’m about to tackle it finally. I think

[@teknofiliak]

8-40

[@ernestoo8309]

Your video would have been perfect if you had mentioned the size of the drill and tap that you used and where you got the tap adapter for the drill press...

[@teknofiliak]

8-40 Tap and Number 28 Drill bit. Got both on Amazon. I don't think brand matters.

[@GM-cr4yk]

He did: 0:48

[@tylercunningham405]

What speed did you run your drill press at?

[@teknofiliak]

Not entirely sure. Just a medium speed. It's just a WEN press. Nothing exciting.

[@angling343]

I took mine to a local gunsmith and they told me the maverick doesn't have enough beef in it to be drilled and tapped. They said after about 500 rounds the threads will start to loosen up. Just wondering how yours held up and if I should do it to mine?

[@burnyburnoutze2nd]

That "gunsmith" is full of shit LMAO mossberg drills and taps all their current production model 500s, 835s and 590s to this drill pattern. The Maverick 88 uses the same basic receiver template as the 500 and 590 minus the machining needed for the tang safety. As long as you torque down the rail screws to the required torque and use blue loctite, whatever rail you have mounted should never budge.

[@Barikade]

Recievers are the same as the 500 +. Just not milled for tang safety as stated above. I was told not to worry about threading barrel cause I wouldn't need it for HD so I'm looking to thread that myself as well.

[@rokinrandy]

Nice. But could one get away from removing everything out of the reciever ? I guess there is no escape cleaning the shavings either way

[@teknofiliak]

Yeah, I wouldn't do it without removing the bolt. Would be awful if you drilled into the bolt. :D

[@rokinrandy]

@@teknofiliak yea true. I also noticed mine those little ridges aren’t true square with the barrel. Seems like it’s all plastic in that area. Guess I’m going to run a laser. Or pop a string. Idk.

[@jasonlopez4855]

Your 4way vice is not clap down or bolt 🔩🧐 on my small drill press i had to drill holes to put on my 4way 🗜️ vice. My big 5foot drill press came with one on it. They work great for milling small parts flat.

[@teknofiliak]

Nope. Really just used the vise as a second set of hands. Not doing milling with it.

[@bills6946]

Should have drilled the second hole at the other end. Then you do the remaining two holes in the middle.

[@teknofiliak]

Noted, I guess. It works out completely fine the way I did it. I was worried the flimsy pic rail could have some bend in it. If I did it your way, it's possible that I would have had misaligned holes.

[@ronalexander4955]

Omg. No 😭

[@SniperUSMC3152]

Why Omg no?

[@CarlPapa88]

If it works, it works.

[@rfdsrd]

Here's the non-invasive and reversible way to add a pic rail to the M88 - kzbin.info/www/bejne/kJrJp2h_qbZkn5o

[@teknofiliak]

Yeah, definitely an option. I think that looks awful, especially that Amazon junk optic. Not really what I wanted, as I wanted a low heigh over bore pistol optic on my shotgun.

[@rfdsrd]

@@teknofiliak It's reasonably easy to find a Romeo5 for close to $100 - that's what's on my 1301 Comp and will be adding one to the M88 I just ordered.

[@teknofiliak]

@@rfdsrd Yeah, I have a few Romeos. I preferred the more open pistol dot on this shotgun.

[@baitball4665]

THose rails are absolute junk. You sight picture is wayyyy above the barrel. Youll end up shooting something right in front of you thinking you have a clear shot. His red dot is much more practical for a shotgun. Any hunter will tell you the drilled and tapped install with a lo profile reflex sight is better for killing stuff. same thing would apply for self defense so in no condition is that big honkin rail better. i had one on my 88 and it was AWFUL

[@sluttybutt]

The thing I'm most concerned about is the orientation of the pic rail/screw holes. It didn't sound like you were sure which end was the "front" or muzzle end.
