AR Rifle pic thread

I didn't have the right height rings to mount this new Trijicon scope onto one of my bolt actions...so I broke out a trusty JP one piece mount and threw it onto one of my 16" ARs. It's a cheapy Alpha Shooting Sports upper on one of my SBR'd lowers with a Jewell trigger. I love the scope. Very bright and clear 56 mm glass. The reticle is fine and clean with a good grid setup. Very nice!

iPhone did some weird stuff with the color. It isn't really that tepid black. lol.

Here are a couple oddballs of mine.

First isn't really an "AR", but it does accept an AR-15 upper and magazines. This one's a 7.62x39 franken-upper using a Faxon mid-length barrel and bolt, and a Fightlite SCR lower with the hammer spring swapped out. It's a little thumper, accurate and very fun to shoot. I have a set of Troy "micro" sights designed for the Sig 556/556R on it, which gives a perfect sight picture on this rifle. I think it would make for a great short-range/brush rifle for hunting deer and hogs.

This one's also a Franken-AR, mostly put together by me. It started out as an SAA barreled upper, and I replaced the aluminum picatinny gas block with a clamp-on steel gas block and added an Architek clamp-on front sight to give it a more AK-like presentation. It has a very good quality WMD NIB-X bolt carrier/bolt.

Lower's an Anderson stripped lower, with a Rise Armament RAVE 140 drop-in trigger.

Not high-value from a trade/components standpoint, but it's had enough rounds through it that I trust it for accuracy and reliability at realistic distances.

That Fightlite SCR rig is a super nice looking gun. Does that lower accept cartridge style drop in triggers?

Thank you! It doesn't, the only commonality it has with an AR lower receiver is the hammer spring and the trigger pins. The FCG, including the hammer, is completely proprietary.

Which model is that? Trijicon I mean
 
What is a dissipator? What does it dissipate? What differentiates a dissipator from any other AR?
Short version;

A “dissipator” or “dissy” is an AR-15 with a 16″ barrel but with rifle length front sight post. There’s some controversy about who invented what, but they can first be seen in Vietnam era photos.

Why?
The concept of the dissipator hinged on two positives:

  • A shorter barrel allows better maneuverability and weight savings
  • A longer sight radius allows for better accuracy

You forgot the biggest thing. Rifle length gas tube with the shortest barrel.

Well, I just did a copy/paste to get him started. :p

However, a 16” barrel but with a rifle length front sight post describes your point...and I did include that. :D
 

I used to have a Bushmaster Dissipator upper, and that's exactly what they did.

A rifle-length gas system with a 16" barrel introduces a problem with dwell time and can cause reliability issues. It really is a better idea to move the gas port back so there's enough pressure to ensure reliable cycling.
 
A lot of people are using rifle (and intermediate) gas on 16" guns.
But mostly with adjustable gas and low mass recoil systems, which makes more sense.
 
I like the middy 14.5" a lot. Maybe my favorite configuration.
 
Yeah mine is actually a regular M4 profile carbine under the handguards. I thought about chopping my BCM, but couldn’t bring myself to do it. And then I’d really kick myself if I couldn’t make it reliable.

Since the shorter gas tube is totally reliable, I guess the only reason for a “dissy” is a long sight radius, or an ugly gun.
Like I've said I've had no reliability issues, the recoil is much much less than mid or carbine, totally user preference

I believe if you just take a 20" barrel and cut off 4", you will probably have to drill out the port in the barrel to make it reliable. They CAN be made reliable, but I have to wonder why Stoner, and Jim Sullivan, picked the gas length they did.

Mine is factory so I'm sure they worked the kinks out to make it reliable, but so far so good, I love that rifle
 
My two attempts at the Dissy.
Top: Spikes Tactical, 16 inch with a mid length gas tube under the hand guards
Bottom: Brownells/ Spikes retro carbine, upper has a 15.5 inch barrel (duck bill flash hider pinned and welded to make it legal) and a rifle length gas system.
Both are 100 percent reliable.
Seems Colt lacked the will to make the original carbine setup work and went to the XM-177 length carbine instead of the original iteration.

After perusing the thread about where do you store your ammo, I emptied half of a safe storing 16 50 cal ammo cans filled with loose ammo. Took the opportunity to rearrange and a group family photo.

Have not yet decided what optic to put on the HK, Probably the Steiner 1-4.

Built one for my wife. Spend my time thinking of how to duplicate its performance without duplicating it. 18" rifle is close, but WAY heavier.
Reliable with under book loads and full power 5.56. Everyone that's shot it has liked it.

That one of mine you shot a while back is still my best one. Haven't really found a better formula! And, I've tried!
 
I gotta stop looking at this thread...I do not have time to shoot what I have, I need to stop looking and wanting more....

Why I haven't looked here, but the wheels were turning today and here I am, and building in my mind.

Looks like a Grendel is coming. Just what I need! Actually, exactly what I want though.
