Is it reasonable for a mechanically inclined person to install these sights at home? I have an 18.5" 870 Frankenstein that needs a useful set of sights and I would like to try installing them myself unless it is very hard to do.

Thanks,
Mark
 
You do realize you have to drill and tap the upper receiver of the shotgun for the rear sight, correct?
Casey, at www.tacord.com did mine for a great price and supplied the sights. I took the hour drive up to him but I suppose you being from AB might not wanna be without your gun for those 1-3 weeks. Also, I am sure there are some local smiths that could deal with it.

"Regarding installation, if in doubt, take it to a gunsmith, but it is not unreasonable for someone with mechanical ability to install it, as I did. You will need a #33 drill bit and 6-40 tap to drill and tap the receiver to install the rear sight. Screws are included. To do this, the holes have to be as precisely aligned as possible. The instructions give the measurements of the holes relative to the front of the receiver, in order to align the sight correctly, but they have to be centered left to right, and the flat stripe on the top of the receiver is a poor guide, being it can be off to one side or another. You definitely want to use a drill press and a vise, or better yet a milling fixture in order to line the holes up and drill them correctly. For the front sight, I elected to drill from the side through the sight, and the original base, and installed a 1/16"x1/2" roll pin instead of the included epoxy. This way the sight can be easily removed if needed, and is more secure than with epoxy, and is the same method Wilson combat uses to install this sight on their factory guns. The only other thing to mention is that the front sight bead has to be cut off and filed down flush with the front base."
 
Get it done - I tried on a gun once - it was not pretty.

Unless you have a milling machine or an extremely accurate drill press/jig setup, it's NOT worth it!!!!

Casey is a wizard. Excellent service, quick turnaround and great guy!!!

IIRC casey charges $149 for the Wilson Combat ghost rings, with the tritium inserts (front+back).
you wont find a better price that that even at Brownells in US dollars.

Well, that was quick and unanimous. I guess I will give Casey a call to see about his services.

Scotty, I did realize that I would have to add D&T holes to the receiver. Drilling and tapping a couple of holes is not really the most intimidating thing I have ever done unless there is something unusually difficult about this job. 6-40 is a fussy size, but I have done 4-40 in both steel and aluminum before without too many broken taps.:D

If Brownell's won't send those sights north it is all moot. Friggin US government deciding we're all terrorists up here.

Thanks for the help, gentlemen.

You are wrong. (And your spelling is wrong too.)

If you have a drill press, go ahead, it ain't exactly rocket science.

Call Brownells. They will ship these sights to you.

(Or send it out to TacOrd, whatever.)
 
It's not rocket science but it does take some machinist back ground to install and align the holes dead center. If you have a drill press with a vice that has graduations in the thousands of an inch sure go for it. Other wise you will be so un-precise you will not have aligned sites.
 
Buy the ones from Trijicon mentioned in your quote, they are identical to the Scattergun Tech model but cost less.
 
I put two sets of Trijicon ghost ring sights on both my remingtons,i bought 3 sets from brownells.They are Trijicons but they have scattergun tech embossed in the side of the rear sight,and are cheeper than the wilson sight even thought they are the same sight.If you have experience drilling and tapping,and have a decent drill press i don't see a problem.Take your time, measure 10 times and drill once.Use lots of oil and make sure to clean the cuttings from tapping OFTEN,they are a very nice addition to the shotgun.
