M4gery Question

[Rbcrusher15]

Hey guys, brand new to this forum, but have read a lot, and obtained a lot of very useful info from reading the threads here, which is why I chose BCM for my mid-length build, so thanks a lot for that. I'm not Leo/Mil., I'm just a normal guy that enjoys building, shooting, hopefully some time training, and hunting with ar's. I'm not a mall ninja/commando wannabe, I work for an armored car company, and i firmly beleive in the KISS method. But that doesnt mean I want to build low quality firearms, so my question is this. I'm building an M4gery, but I'm stuck on what receivers to use. I know the topic of receivers has been beaten to death, so I sincerely apologize b/c this is a question asked/answered a million times over, so I'll do my best to maybe ask it in a more precise way. My parts list is as follows:

Barrel: Colt 16" w/pinned fsb (G&R Tactical) already have
BCG: Colt (G&R Tactical) already have
LPK: Colt (G&R)
RE/Buffer assy: Colt (G&R)
Stock, Pistol grip: Colt (G&R)
Rail-Maybe: Daniel Defense E-Z CAR 7.0, or Colt Round hand guards
Rear Sight: LMT fixed
Lower: Seekins/Mega/ Armalite?
Upper: Seekins/Mega/Armalite?

The receivers in question are just those that I'm considering at the moment, but my problem is that I cant help but feel like I might be selling the build short. Am i going to be gtg with any of those, or should I just pony up and buy the Colt, or even Noveske receivers when I can find them? Thanks for any advice in advance.

Forgive me if I am missing something, but it would appear to me that with the exception of the receiver components, you have basically pieced together a Colt rifle without the factory assembly/inspection/QC process being part of the equation.
I don't think you would be losing out by using receivers from someone other than Colt, but I must ask.... Why not just snag up an LE6920 and call it a day? Then you would have all Colt parts, Colt quality control, inspection and assembly, as well as a Colt marked receiver that has an M4 Carbine rollmark on it. They have been going for as little as $850 recently.

[Airhasz]

I'd get Colt receivers since you already have Colt parts, but many other will served you well also.

[Iraqgunz]

Out of curiosity. Why didn't you consider getting a Colt 6920 and then just add a rail, etc... What did you pay for the parts thus far?

I guess if it's going to be an M4gery why not consider a real Colt lower? They can be found on Gunbroker which is where I got mine. I only bought it because I already had a Colt 6920 barrel (from another re-build), a Colt upper, BCG and the other components to build it out like I wanted.

[kpinole]

Don't think you'd be saving much mone doing it like that. Just get a Colt rifle like othere said.

That's definitely going to happen at some point. The reasons are, upon hindsight, probably kind of stupid actucally now that I think about it. The much smaller reason is b/c I enjoy building them myself. Mostly b/c that's just kind of my way to quit smoking. Throw the $50/week I would normally spend on cigarettes in an account and 30 days later there's a new part. I have a tangible reward for my efforts ya know. The larger reason is b/c of the political climate being the way it is. After Aurora and Sandy Hook, God rest them, and the AWB talk started, rifles and parts flew off shelves as I'm sure you guys know, and the parts dried up just as fast, and what didn't go quadrupled in price, especially lower receivers. Idk it just seems like a way to get the parts that disappeared fastest now, and have them for down the road, instead of waiting 6 months when anything could happen in that time. That being said, if it does I can just save, and until/if that happens I can just buy the parts I have money for if I dont have enough for a complete rifle yet...

But yes after this rifle is done, either a complete colt, or BCM is going to happen.

[Sticks]

You've come this far, I agree, try to find a Colt receiver set.

Other options would be a Vltor MUR upper and a variety of good stripped lowers out there, like Aero, BCM, PSA, Noveske...

[samuse]

All you have is barrel and BCG so far right? I think you'd be fine with any good receivers, but I am really partial to Armalite's rollmarks. Billet lowers just look weird.

Are you referring to M4gery as a clone of mi issued M4, or are you just calling any carbine an M4gery?

If you're wanting to clone, you need a KAC RAS, a MaTech buis, and an Aimpoint M2 or M4 and you'll be there.

I would also reconsider the Colt receiver extension, an LMT or BCM has six holes, vs Colt's four.

A Daniel Defense rear sight is a lot slicker than the LMT. If you're gonna have all the knobs, might as well get a whole carry handle and have the benefit of stiffening the upper (tiny benefit).

A BCM stock and grip are a lot cheaper than Colt and seem just as good.

You have a solid barrel and BCG. Attach barrel and BCG to this:

Then attach upper receiver group to this:

And now you're off and running. This BCM/Colt M4gery will do everything a Colt M4gery can do. Really, no bullshit! :cool:

[Iraqgunz]

I just saw what parts you have. I would simply look for a factory Colt and then modify it from there.

[Rbcrusher15]

Hey fellas work has been calling my name all day, so this is the first chance I've had to post. I appreciate all of the advice and info that you've given

[Rbcrusher15]

Samuse, Ya I apologize for that. I use the term m4gery a little too liberally sometimes. I'm pretty much just going for a basic m4 style, maybe with a rail at some point, but it will definitely start life with basic furniture. And thank you for mentioning the other parts. All I looked at was the material the colt RE was made of, didn't even notice it only had 4 holes. I've used LMT RE's before, and they have worked out well, and I will be going with bcm furniture after all. All I've looked at until just now was their upper receivers. And you're definitely right about the DD rear sight.

[Rbcrusher15]

Iraqgunz, The factory Colt 6920 is going to happen in time. Honestly the only reason I'm building this one from scratch, as dumb of a reason as it might be to most people (it's working for me for now), is to help with the process of quitting smoking. I've tried before, but I've never really seen any kind of reward (other than not dying as fast :p). This way gives me something to save for and work towards one piece at a time.

[Rbcrusher15]

3 AE, I'm glad you said that. I've only built 3 so far, and I'm not going to lie, I actually advised against it when I spoke to a friend at work friday. Not because I dont think he can do it, he can, but because he gets frustrated easily, and I recommended that he take a serious look at buying a BCM upper, and lower of his choice, and putting them together. It started as a question about buying a bushmaster from Bass Pro for $999. Ya, $999.... Pretty sure you can slap a BCM upper and lower together for what, $100 less, and get a much better rifle. Actually the more I look at it, the more I regret not doing it myself...

[Rbcrusher15]

Sticks, Definitely going to try. Is PSA really good? I think I may have let myself become a victim of if it doesn't cost $200 per receiver its no good disease... I'm wrong. Right?

PSA is a company that cropped up on the net big time a few years back. They have had their growing pains, but the quality of the components (PSA not PTAC) is on par with the higher end companies. and other than customer service issues, I have not really heard anything bad about the PSA branded items, no more than BCM, Colt, Noveske, or Daniel Defense.

Are they top notch - no, but at $59 for a blem stirpped lower - that I have 2 of, and have no blemishes and no problems with after 8k rounds on one, and 2k rounds on another, why question it?

The Vltor MUR upper I think is probably the best upper out there. A little beefier around the critical points, and is still the same dimensions as the Mil Spec measures out to where it matters.

[Rbcrusher15]

Well definitely can't argue with 10k rds thru 2. I played with a Vltor MUR upper before, and it was awesome.

[levik97]

May I suggest that you get an ALG trigger (if you want a mil-spec trigger), a six position RE (from BCM or other quality company) or possibly even a VLTOR A5 RE, a BCM/Magpul/Umbrella Corp/etc grip (the A2 grip sucks IMO), a Daniel Defense rear sight, a BCM blem lower, and either a BCM blem upper or the VLTOR MUR if that's what you want. Obviously these things aren't necessary for a good AR but these things are all high in quality and some even save you money.

Also, I commend you on trying to quit smoking. I myself chew a hell of a lot of Copenhagen and I should probably quit that too. Shit gets expensive.

[exkc135driver]

First let me say that you have chosen what, IMO, is an excellent way to stop smoking … use the money you save to pay for something you want. Congrats and good luck with the program.

Depending on your personal financial situation, you might want to consider buying a 6920 and, for now, keeping the parts you already have. That way you have a properly-marked Colt lower receiver, Colt QC, etc., with the associated resale value. You can take your time building your next rifle or just hang onto the parts, knowing that when (not if) the next AWB/anti-gun president/whatever occurs, you’re OK for parts for another build.

[Rbcrusher15]

Hey everyone thanks for the advice. I'm going to take you up on all of it. The special BCM is running right now is hard to ignore, and a Colt upper, or LMT, are also going to be options especially considering the warranties and and guarantees associated with them. And since I already have an M&P Sport I can slap the new upper on the lower until I get the New one. So again, thanks for the advice.
