huggytree Posted November 26 Report Share Posted November 26 (edited) Picked up a colt le ar6450. Im A sot. If I pickup a post sample Rdias what’s needed to make my gun run. It does not have the block in the lower. I assume a different hammer and selector. Edited November 26 by huggytree Quote Link to comment Share on other sites More sharing options...
Uncle Zeek Posted November 26 Report Share Posted November 26 Mine just has the M16 fire control group with the rdias - no modification of any kind to the receiver. Quote Link to comment Share on other sites More sharing options...
huggytree Posted November 26 Author Report Share Posted November 26 (edited) Looks like the factory le bolt is FA I’ve read about bolt slap from a Rdias? What do no law letter Rdias’s typically sell for? Edited November 26 by huggytree Quote Link to comment Share on other sites More sharing options...
MPFiveO Posted November 27 Report Share Posted November 27 In addition to the DIAS you'll need a hammer, trigger, disconnector and selector. You'll first need to check your hammer and trigger pin sizes to make sure they're .154 and not .170 as there are no M16 parts for the .170 size pins. Not exactly sure what you mean by bolt slap. The DIAS functions and behaves exactly like a pinned mil-spec GI auto sear, except that it is also functioning in the semi auto mode where the factory pinned sear rotates forward out of engagement. The 9mm's do sometimes exhibit trigger slap making shooting it a bit uncomfortable on your trigger finger. Make sure you have the correct heavy 9mm buffer. Bolt bounce can be more prevalent in the 9mm blowback, there's absolutely nothing to keep the bolt in battery. Lastly, invest in a pair of stainless steel hammer and trigger pins. They're tougher than the carbon steel pins and less likely to break. Broken fcg pins will quickly trash your receiver. Quote Link to comment Share on other sites More sharing options...
Got Uzi Posted November 27 Report Share Posted November 27 Colt 9mm SMG’s are one of my favorites. You’ll need the following M16 parts: Hammer Trigger/disconnect Selector You will also need to make sure to use a carrier cut for full auto use. Buffers-you can use the OEM Colt 9mm buffer, but they suck. I have the Kyn-shot 9mm HD hydraulic buffer in mine. It really tones the gun down and makes it nice to shoot. Ditch the OEM hammer/trigger pins and get a set of KNS anti-walk pins. You may have to time the DIAS to work with your gun, I’ve run into that before. 9mm guns can be hard on DIAS units as they are pretty violent compared to the standard 223/556 guns as stated above-they are straight blow back. Post Sample DIAS units can be $500 or so a pop if they are No Law Letter units. I’ve got some in the works now. Waiting on sear trips to come back from heat treat so I can test them Quote Link to comment Share on other sites More sharing options...

JoshNC Posted November 28 Report Share Posted November 28 The Colt lower will need to the pocket behind the hammer/trigger milled out to accommodate the DIAS. Quote Link to comment Share on other sites More sharing options...

Only if it's a newer one. The Type A and B did not have a sear block and had normal size pins. The current model does have the web of material in the fire control pocket that would have to be milled out to accommodate the DIAS. Quote Link to comment Share on other sites More sharing options...

Based on the OP stating it’s a LE6450, I assume it is one of the later guns that has the web blocking installation. Quote Link to comment Share on other sites More sharing options...
