The last 6 months or so I've been collecting parts to build three different AR-15s.  In reality I'm not quite done collecting parts to finish two of them.

These three projects are:  My interpretation of a SPR, a retro M-16A1 clone, and a modern lightweight rifle w/ 20" barrel.

I'm still waiting on both the upper and lower receivers from NoDak Spud for my M-16A1 clone, and my upper for the lightweight rifle is supposed to come in tomorrow.

Here's a picture of all the parts I have for my SPR:



The parts include:

-Rainier Arms Ultra Match A4 Upper
-Daniel Defense 18" S2W barrel w/ pinned low-profile gas block
-Mil-Spec barrel nut
-Bravo Company mid-length gas tube
-Young Mfg National Match BCG
-Rainier Arms Raptor Ambidextrous Charging Handle
-Troy 13" Alpha Rail Hand guard
-Troy Flip-up BUIS set
-Troy Low Profile QD swivel socket for Alpha Rail
-Troy Rail section for Alpha Rail
-A1 Flash-hider w/ lock washer
-Spike's Tactical Punisher Lower
-Spike's Tactical Billet Trigger Guard
-Spike's Tactical Lower Parts Kit w/o trigger group
-Troy Ambidextrous Safety
-Magpul OD Miad Grip
-Magpul OD UBR stock
-Spike's Tactical Mil-Spec 17-7 Buffer Spring
-Spike's Tactical Carbine Buffer

Not shown:

-Geissele Super Dynamics Combat trigger Group
-Magpul UBR strike plate

I have some Duracoat in Magpul OD green (to match my stock and pistol grip) that I'm going to use to paint the upper, lower, hand guard, and Alpha rail section this weekend.  I should be able to assemble it sometime next week.

Updates and pictures to follow on all projects.

Score!  I'm interested in the M16A1 clone, but I'll be patient.  I'm watching this terrible zed movie right now so thanks for the distraction.  I like the longer rail on these types of rifles, since I got the 9" and it covered all of the gas tube but 3/8" and the gas block and that always worried me.  If I build again I would go with the Troy TRX 13"--what do you think of their Alpha?

I can't wait to see the finished project.  I was planning on putting a SBR together over the next few months for a backpack get-n-go rifle but that buffer tube presents a problem of fitting it in the pack.  That said, what's with you and 20" rifles?  Velocity?

Mostly velocity, plus you don't see many 20" barrel ARs around much.  I'm quite impressed with the Alpha Rail.  I ordered one for each of my modern rifle builds (I'll have to modify the one for the lightweight rifle as it is slightly too long for my application).  It appears to install easily, is very light weight (10.05 oz vs. A2 handguard @ 9.85 oz), and you only have the rails (other than the top one) that you add as needed (keeping down the clutter).

It's funny how deciding to build a new upper to have something lighter evolved into building three complete rifles.  First I was just going to build a SPR upper to use with the lower I assembled to have something lighter, but just as (or more) accurate.  Then sell my current 20" Hbar upper.  I then decided that I'd never get anywhere near as much as I payed for it, and it would be hard to move seeing as they aren't very popular.  So I bought another lower to use with a lot of my left over part to re-build the HBar as it was originally. 

Then I decided to build a M-16A1 clone.  In collecting parts for that build, I received my new barrel from Fulton Armory for it.  I was quite impressed by the quality, so I got an idea...  I'd build yet another AR-15 using a "pencil" profile 20" barrel from Fulton Armory.  This time it would be a modern, light weight rifle.  It should be just over 7 lbs when I'm done.  And it'll be something different.

If I do end up keeping my 20" Hbar, I will pull the barrel off and send it in to be re-contoured to the A2 "Gov't" profile.  It's cost effective to do it that way.  Significantly less than buying a new barrel.  It won't effect accuracy, and it'll lose atleast a pound.

Well, I'm really looking forward to seeing these put together.  Especially the 'Nam-era clone.

Update:

Roadblocks have temporally postponed my ability to paint the upper/lower receivers and handguards with Duracoat.  Mainly weather.  But as soon as the paint is dry enough to assemble my custom AR-15s, I will post pictures.

Here is a picture I took prior to prepping my light weight rifle for painting:



I was test fitting to make sure the handguard would fit.  I had to remove about 1/2 inch on the 13" Alpha Rail to get it to fit.  It's using my old lower from my previous AR-15 build with the light weight upper.  The upper is made up of the following parts:

Del-Ton flat top upper w/o M4 feed ramps
Fulton Armory 20" pencil barrel w/ F-marked FSB
Young Mfg Hard Chromed BCG
Modified Troy 13" Alpha rail
Troy flip-up Rear BIUS
Rainier Arms Raptor Charging Handle
A1 Flash hider

If you're willing to spend the money, I really like the Raptor charging handle.  Very strongly built, ambidextrous, and it gives the function of extended latches w/o actually being much wider than a standard charging handle.

I had exchanged emails with NoDak Spud last week, and they said that the earliest they'd be shipping out my Retro receivers is the end of December.  So it will be a while before that project will be complete.  I kind of expected the wait, so it isn't a big deal.  At least I have all of the other parts for that build in hand, so I'm only waiting on the upper and lower receivers.

Wow, that came along really well!  What is the weight with a loaded magazine?

Thanks!  The lightweight rifle comes in at 7 lbs 5 oz. empty.  The UBR stock really adds some weight.  I have a feeling I could shed another 1/2 to 1 pound if I went with a standard fixed stock or an M4 type stock.  But the UBR is just so nice, and the way the light weight rifle balances now (at the pistol grip) it feels even lighter than it is.

To put things in prospective:

My HBAR as was configured, empty w/o scope+mount = 9 lbs 2 oz
-w/ scope+mount = 10 lbs 9 oz
My HBAR configured as an A3/A4 with carry handle sight = 8 lbs 12 oz
Your (RCS) old AR15 carbine upper w/ RRA lower = 7 lbs 7 oz

----------------------------------------------

I'll tell ya, buying quality components isn't cheap!  All of these rifles will end up costing more than I care to admit.   In a way I'm glad that I wasn't able to get all of the parts I needed all at once.  It made it to where I could actually afford them.

That's LIGHT!  I've never felt the UBR, but mostly everything Magpul comes out with fits just right.  Even their MOE (bottom tier) stuff is sweet.

Update:  I finally got them painted and assembled last week.  Both function 100%, no malfunctions of any kind for the first 180rds through each.  I'll zero sometime soon, so I'll be able to report accuracy then.

And here they are:



The top one is my light weight rifle w/ its "pencil" profile 20" barrel.  The bottom one is my interpretation of an SPR with a Daniel Defense 18" Strength-to-Weight barrel.

Gotta couple questions for you, Jay;

How much does your pencil-profile barrel heat up?  And would you be concerned about your gas tube melting during a rapid-fire session?

I'm not too worried about the "pencil" profile barrel getting too hot.  One, you never really hear about M16A1s losing too much accuracy when they get hot.  Two, M16A2 and M4 barrels are actually skinny under the handguard.  And three, it's not select fire. 

It would be almost impossible to melt a gas tube on a semi-automatic AR-15 type rifle.  I've only ever heard of that happening when they run selectfire guns on full-auto, with the intent to run them until something breaks.  Even then it usually takes dozens of magazines being fired back-to-back.

Great answer!  Thanks for the speedy response, too.

Update:

Zeroed the "Light Weight" rifle today.  Using PMC 62gr 5.56 @ 50 yds from benchrest it groups just under 1".  More than addiquit for what it is intended for.  Plus I'm very sure with magnified optics and the right ammo, it would do under 1 MOA.

Update:

My M16A1 clone is finished!

My retro receivers from Nodak Spud finally arrived at my gun dealer on Thursday.  Here is what they looked like after I picked them up:



I assembled the lower receiver and the small parts onto the upper receiver Thursday night.  I installed the barrel assembly this morning, and here is the finished product!



It's a mix of original, reproduction, and new parts.  I wish I would have picked up one of those parts kits they had when they were everywhere, would have saved me some time and money.  It's not a 100% faithful copy, but it's very close, and I don't think it would be worth my time tracking down some more original parts to make it so.

I plan on shooting it tomorrow to test for function and break it in a little.  Later next week I plan to take it to a formal range to zero it.

It is quite light... it weighs just shy of 6 lbs empty!

I like it a lot!

That's bad as hell.

Shoul've made it with a short barrel... Colt Commando style.

Nice, man. It's very handsome. That's a rifle I'd be proud to own. Good work. And I agree with the sentiment of it likely not being worth it to track down more of the original parts. GOOD WORK

Thanks man!

The parts I'm talking about really are just small, detail parts.  Like the correct selector lever, mag release button, trigger guard, and take down pins.  Only a very select few would even notice.  Everything really important is correct.

And for your viewing pleasure... a Family Photo:

Update: I was finally able to zero my SPR today. I've got to say, this rifle is fantastic! It reliably shoots under 1" groups @ 100yds off a bench rest (w/ 5.56 NATO 62gr Green-tip LAP). Can't wait until I can get some match ammo to try out!

Funny story; The windage didn't change from between my HBAR and my SPR, only had to adjust for elevation. I thought to was interesting.
