moxdmguy: Yes I pinned the trigger group and action to the stock. Some people use the aluminum binder pins that are for putting paper together in a binder, but I could not find the correct length for my customized Fajen stock, so I bought some I think 3/16 round stock and took my drill press, bored each end and tapped them for some allen head pan screws from the hardware store too. It was a bit tricky getting the holes centered to drill and tap, but I had 3' of stock left to get it right. Then I put the action back into the stock and held it very tight, while taking a allen wrench that was just the same size and using a mini torch, heated up the small end of the wrench, and from the bottom of the stock, without the trigger group just the action in I burned a small hole thru the stock in the holes that the trigger group pins the action/stock together. I had cut the pin to be just 1/16" shorter than the stock, so that I could tighten them up secure enough to stay put. Some people do the front and back, I just did the back one. I may have read about how someone else did it on "Rimfire Cental.com". I have not bedded the barrel or action, just did this for now. Hear is a pick of mine done.
When you mount a RDS at a proper height so that you can still see your BUIS (Back Up Iron Sights) then if the battery ever goes dead on you, you can still see your Iron Sights thru the scope, but the Irons should be in the bottom 1/2 to 1/3 of your RDS. You use a RDS with both eyes open and can acquisition your target faster that way. These work best if you have at least the rear sight as a fold down one so you don't have to have it up all the time, just when you need it, and it's OK to have both front and rear fold down sights. http://www.vortexoptics.com/product/vortex-strikefire-red-dot-scope-for-ar15 This will give you an idea of what co-witnessing is if you look at the option pics at the right under the pics. Hope this helps answer your question.
http://www.bhphotovideo.com/c/product/563215-REG/Vortex_SFRD_1x30_StrikeFire_Red_Dot.html I just got one of these delivered to my door for $136. got the AR15 mount one for co-wittnessing. get a $25 gift cert too so the second would only be $105 + frt. Havent had time to site/test yet. They do actually have one of the best tried and tested warranties around too.
Do a search on "m4carbine.net" there are a few "Opinions" on Spikes stuff from users that have them. I personally will go for a dedicated upper when the $s allows it, just to have a better twist rate for the lighter bullets.
I put the complete Volq trigger pack in mine and it sure runs smoooooth now. Verry easy parts to put in. IIRC, I used a small punch to line it up to put the pins back in. Just changed scopes on it so need to get out and sight it in again. I also pinned my trigger group/action to my stock and have not shot it yet. Gotta "Gitterdone"!
Hello, new guy here. Just read about this site from another member here, who is on another site I'm on. It's late now, but will be getting back here soon. Thanks for the referral Steel. ;)
