View Full Version : AR Upper Question

09-15-2008, 11:15 AM
I have a Half finished AR-15 that is in deperate need of an Upper, I have debated buying one or building one, and I thought who better to ask then the guys at calguns. So I have a Doublestar lower, DPMS parts kit and CAA 6-position stock, I love the look of the tactical style guns but want something I can shoot long distances with. I'm already planning on a Bipod, and was thinking of a 20-24" barrel. Does any one have any thoughts as too what I should do? I think it would be fun to build an upper myself but would it be cost effective over buying one? and would I need any special knowledge?

At minimum you need a vise, an action block and a barrel wrench (~$50 assuming you have a vise). It's not the same as building a lower, but it's not prohibitively difficult. I wouldn't recommend it unless you're willing to

Buy the Stag, RRA or WOA... it will run you about $600. Building one would cost about the same, if you include the tool cost.

I'd love to build one, cause I would know exactly what went into it and could make it custom, but then again I am still getting in to the whole shooting/AR scene as this is my first rifle I've bought.

I recently bought a RRA DCM flat-top upper. The fit and finish is superb. 1 in 8 twist should be good for long range as well as close up. The removable carry handle makes it easy to mount a scope for long range or put the handle back on for match shooting. I will admit to one thing, I didn't think it would be as front heavy as it is. I'm thinking about putting the 3# weight in the butt stock for balance. I bought 2 receivers from Spikes, and the next one will be either a .22LR or a lighter weight upper with a 16" bbl for fun stuff.

If you do not have much experience working on guns you might be better off buying a complete upper. If you build one you will have to worry about headspace and buying the tools too.

What exactly is headspace?

Don't build your own upper.

Don't build your own upper.

Well, he CAN take it to a 'smith to verify or set.

I kinda have an Idea but I don't think its right, I was looking for a verification. Any way has anyone ever dealt with JT distributing? they have a bunch of Uppers at pretty good prices, but I don't know much about the quality

I got a kit from JT and I'm very satisfied with it. I'm gonna get an M4 kit from them if i ever stop buying AKs. I have not really seen any negative stuff about them. JT is what I would recommend

J&T is a more respected bottom tier seller.

If you're building a varmint rig they should be ok. I wouldn't choose them for a combat carbine.
