How much do you think a gunsmith would charge? $25? $30?

$65 drill press will get the job done, and you will use it for lots of other jobs.

The front trunion is only about .125 thick. I used a 50 year old bridgeport mill I have in my shop on my last .223 ramp, but you could easily do it with a hand drill as long as you use a center punch to get started.

If you are installing an extended feed ramp for a .223 - I'd also recommend modifying the feed lips on a mag first and installing the mag before your line up the center punch and the guide to make sure you're on the bottom of the round trunion.

its for the x39

[223addict]

The x39 bullt guide doesn't extend into the mag well like the .223, so you don't have to worry about that. You could still get away with the hand drill if you don't have access to a drill press or mill. I assume your using the dinzag guide. If so, he probably supplied the drill bit and tap. There's really no way you could F it up.

I'm in Carlsbad, San Diego. If you want to make that long trek down here I can do it on my mill. Or you can post on the saiga 12 forum in the tech section and see if there's anybody closer to you.

Ditto 223Addict's info.

I was surprised at how thin the trunion was right there. Ironically, I also used an old Bridgeport to do the work. Definitely overkill for this application. Because of the thickness (or lack thereof with the trunion), you're only going to get a couple of threads worth of engagement. Use the supplied bit and tap and you should be fine.

As stated, centerpunch your hole, and then take your time making sure you're drilling perpendicular to the plane of the receiver. The drill will go through quickly. As for the tap, take care to ensure that you're starting it straight because there isn't really enough material to stabilize the tap in the hole if you're canted a little bit. Test fit/fire, then lock it down with locktite. There are some good illustrated instructions on Dinzag's site under "downloads".

FWIW, I went a looked at the drill press from Harbor Freight that Vandal linked to. Not too shabby for the $$. Ya gotta swap the drive belt between pulleys to change speeds, but otherwise it looks like it will handle small jobs nicely.

A bridgeport is never overkill.
The rigid spindle allows you to center-drill.
Hand tapping in the bridgeport (disengage back gear without lifting the pulley) allows for perfect alignment of the tap everytime with a sensetive feel so you don't break taps.

Randall, I guess what I meant by overkill, is that the average DIYer shouldn't worry about not having a mill for this operation. I have access to one (it's my Dad's) so I use it when I can. 9 times out of 10, having access to it allows me to end up making super simple stuff really complicated If you ever see a good deal on a set of DROs for one, shoot me a PM. And by the way, do you have any midlength gas AR15 JP VTACs in stock?

I picked up my 80's bridgeport clone for $610 with the Sony DRO on it.

I have a JP 9.0 Vtac in-stock.
