So, I guess mine is a R6430. It has large fire control pins, a sear block, and did not come with a bayonet lug. It is pre-ban with the collapsible stock and I registered it as an SBR, had the barrel cut to 10-inches so the flash hider is butted up to the front sight base.
I bought it because I saw the Gemtech Talon SD at the SAR show in Phoenix a couple years back and thought I had to have one, still have to have one, but don’t yet. I registered the weapon because of the five-inch barrel in the SD and for the time being I just use the cut down 10-inch upper. The gun “looks right”, handles great and is a lot of fun to shoot.
I never considered the large pins and sear block to be an issue as I’ve never desired to make it full auto. If the opportunity do buy a registered DIAS did present itself and I wanted to run it in this weapon I can have John Norrell cut the sear block out and furnish me with M-16 FCG with large pin holes. Like I said though, I don’t plan on doing this so it is a non-issue for me. What I didn’t want is a flat side gun or something with a large pivot pin. Just my personal opinion or tastes but I don’t care for either and my gun has the raised fence and a small front pushpin.
As far as trying to retrofit non-Colt parts and mags I’m done with that. I’ve tried using my upper and buffer on different M-16’s with different drop in mag blocks and different non-Colt mags and nothing has ever worked right. If someone else can get these things to work that’s great, but I’m just sticking with Colt stuff for now on. I have one 20 and one 32-ronud Colt mags and one converted Uzi mag and they all work great. As finances permit I’d like to get a few more Colt mags but I’m always thinking each 32-round mag is 1/10 of the Talon SD.
For an AR it is extremely expensive. I’m not very mechanically inclined; actually, some might say I have a negative mechanical inclination. Thus, I am somewhat stuck having to buy the premium parts that aren’t cheap, but the gun works fine, it’s a different twist on an AR and it is a lot of fun. That said, I’d recommend one, and for the average person to use all Colt parts, not a kit, unless you’re close friends with the Dermel tool god.
