I don't think it is. I've got plenty of RS parts on my guns. Some out of necessity to replace broken or worn airsoft parts, some are to make further mods possible. Some of the parts I've put on I had kicking around, some I bought and traded for. None of the RS I bought were more expensive than airsoft counterparts, but all were better quality, and have held up tons better than the stuff they've replaced.

Again, your mileage may vary. I bought a simple 4x Colt RS scope from Lupo years ago that I still use at pretty much every game. Cand I zero in a shot with it? Nope, airsoft doesn't have the range. But it has saved many a player from friendly fire incidents, and it's shown me once or twice that an opposing team was about to complete an objective we needed to prevent. Very handy. Certain scopes do retain zeroing, like the issued Elcan. As long as you don't rezero it on your airsoft, it'll still be at the same zero when you put it back on your RS.
It's very easy to prevent breakage on them too. Just cut out a circle of lexan, install behind the flip up cover and you're done.

I've got one I put on my ICS/TOP guns, but I'd never put it on a plastic body. Mine's kind of big and would tear a resin body apart in no time. Something smaller like a TIM-14 you might be able to get away with on plastic though, but since the sight is almost always worth more than the gun, I'd never do it.

LaRue are pure hot. I know Ronan has one on his PTW. Their is no airsoft copy of those or of Daniel Defense rails. You need a PTW to put them on since the threading is the same (hence why PTW's accept real steel accessories).

Take in consideration that LaRue and DD rails are hard and expensive to find inside Canada. Do you really want to 'jam/force' a ~$500 rail on a pot metal body?

Good luck with your project.

Often putting RS parts on an airsoft gun is the only way to get a desired look/function.

Before airsoft ambi-catches were released, I had modded a RS Badger Ordnance ambi-catch onto an ICS cocking handle;

Before airsoft AKSU's were released, I modded a RS AK74SU folding stock onto a AK47 (and then AK74) metal body.... etc and so forth..

Honestly, its been done. Steel always wins against pot metal/aluminum.

That Madbull re-threading die is steel, too.

My only point of emphasis was using a proper tool (armorer's wrench) to get enough torque to do it right without damaging anything, lubing it, and not over forcing it to prevent cracking anything.

The latter points would also apply to using the die.

And the steel barrel nut won't get much more damage to it from pot metal than a knife gets damaged by a carrot.

hrmmm...i live in hawaii (usa) so getting the rails themself would be no big deal. ive even seen them at some of the gun shops over here. i dont really wanna jack up my gun...even though it is still in the early phase. i dont have any tools for real steel guns so i probably wouldnt be able to do drakes mod on my own.

perhaps i will have to switch over to a PTW. ive read some pretty good things about them but im pretty partial to having the systema logo on the lower receiver. i saw a colt lower for the ptw on redwolf but it seems it was a limited run item. do you guys know where and how much it would cost to get a vltor mur modded to fit the ptw?

Go see the Team Killer Studio guys in Honolulu if you want a PTW and related stuff, but I'm sure you knew that already;)

actually i DIDNT know that...do you know how i could get a hold of them?

usually real stuff is cheaper then airsoft shit...plus its been to iraq! if you know where to get it.

An AR15 Armorer's Wrench is like $30 and available online.

their site sucks! hopefully they respond to my email...thanks for the help though!

dude, you are in the US, what are you doing with a TM while you can get a PTW fairly easy?... Also, there is no restrictions on purchasing any brand you like in regards to rails, including LaRue and DD's .... you want to look at some sweet setup take a look at this tread that are PTW's photos...most of the people there is from the US which for them having real steal parts on their PTW is easy to have access off... and if you want you can always ship me some LaRue rails ;)
