View Full Version : those cool AR-15 handguards (how?)

I might break down and get an AR.

I was in the Army in the 80's. To remove the handguards, you had to pull this spring loaded ring in a backward motion... and this would release those guards.

Now, I see a different kind of hand guard.... or perhaps they are called "rails" at this point. I do not see that spring loaded ring, but I like that.... I like the newer system.

My question is: If I were to buy a mid-level AR such as one from Palmetto State Armory... and it has the old spring-ring system, is it a simple matter to change that system into a more modern rail system?

If you happen to buy a set up with the spring loaded delta ring you can get a rail system that fits in just like to plastic gaurd came out. This set up puts pressure on the barrel and some say it can shift POI as the barrel gets hot so some opt for the free floating rails that do not touch the barrel at all. There are all kinds of options for the gas block mounting and rail systems. It just depends on what you want and is the reason the AR platform is so popular. Here is a example that fits the carbine lenght system and uses the delta ring set up and some additional machine screws.

If you're referring to a conversion to a free-float handguard, yes- it's simple.
There's a nut for the receiver with a hole for the gas tube. Just torque to the correct position...

If you look at the photo, you will see that good ol' friendly delta ring right behind the free floating quad rail. There are various ways of attaching a new hand guard....some still use the 50 year old delta ring.

Do you have a few close-up photos or the brand/model of your floating handguard with delta ring? I'm having a very hard time seeing how this could be a fully floating assembly. Thanks.

Midwest Industries make a two piece free float hand guard that you cut the delta ring off and then install the hand guard rail over the existing barrel nut. If you don't care about free float then there are many drop in options out there . I have come to like MI stuff its quality made in USA at affordable prices.

Here is the installation write-up (http://www.stu-offroad.com/firearms/ddomega7/ddomeaga7-1.htm) for my DD Omega free floating rail.

They do have drop-in quadrails that you can just install/replace your handguards. They go as cheap as $40 on Cheaper than dirt, to a few hundred $ for name brands like Daniel Defense. The downside to the cheaper ones is that they are not as solid fit as the higher-end or free-float rails.

Free float rails are the best type, but for normal plinking and HD, the drop-in quadrails should suffice. Here is another pic for reference.

If you don't want to spend the $$ for a free float, a quality drop in rail can be had from Troy, such as the 7" CAR/M4 Drop-In BattleRail. I ran one on my M&P15 for a while and it is now on my backup, an Eagle Arms EA-15. It installs in the same manner as the factory hand guard.

You can get a Float tube which is used for hand guards in the Service Rifle matches. Which will let you use the regular drop in hand guards while making it a free floated barrel.
