I started this thread here because I didn't want to hijack another good discussion. If you look at pages 10 & 11 of this thread https://www.indianagunowners.com/fo...s_in_quality_order_from_best_to_worst-11.html you'll understand why I started this.
So anyway, I wanted to take a bunch of pictures tonight of my colt 6920 and my delton disipator kit gun. Being an internet forum we can't seem to stop talking about mil-spec this or comercial buffer that. What's all that mean to the average guy on INGO? We can decide that for ourselves, but I took a bunch of pictures tonight and I'll admit they didn't turn out that great, but hopefully they help out some. In all side by side pictures the colt piece is on the left.
Colt 6920 on left, Del-Ton Dissapator on right.
Bolt carrier groups from top view (6920 on left, DT on right)
Closer view of gas key staking (6920 on left, DT on right)
Side view, shows part of the full auto cut (6920 on left, DT on right)
Other side (6920 on left, DT on right)
Bolts (6920 on left, DT on right) The lettering didn't come out in the pictures so I'll just type in what's written on the bolts later.
Colt feed ramps
Del-Ton feed ramps
I didn't get any pictures of the 6920 barrel profile because I was in a rush to get this little amount done, but those pictures are all over the internet anyway.
So what can we notice:
*Gas Key staking looks identical to me.
*One carrier is full auto, the other isn't. With semi auto rifles you decide if that matters to you.
*Both bolts were marked in their own way about being tested. Unfortunately neither markings really came out in the pictures.
*The feed ramps on the Colt seem to be cut just slightly deeper, but not by much.
*The colt has a mil-spec diameter buffer tube, the delton is commercial. This wasn't pictured, but it's just another difference.
So what does all this really mean? Well, if I was ever going to convert the rifles to full auto the colt would have some advantages, but since that's never going to happen it's more of a moot point.
The mil-spec buffer tube is stronger, but that doesn't mean that a commercial buffer tube is weak. I don't plan on butt stroking anything with a carbine so I don't really care on that either.
The bolt carrier assemblies seem to be on par with each other in regard to the gas key staking and the bolt testing.
The most interesting fact is that both rifles have been equally reliable and fun to shoot. The colt has probably had another 500 - 800 rounds through it than the del-ton has, but both have been 100% reliable for me throughout their lives. Obviously, I'm impartial to the mil-spec vs non mil-spec hype since I've bought both, but I'm always curious when I start seeing the AR tier threads and how people rank rifles. I'm not saying either way is right or wrong, but ultimately at my house I've chosen the del-ton to be my accessable rifle is case I need one. The largest reason why I did that is because I've set it up for night time with the XS night sight on the front post and a flashlight and I didn't feel like doing that with the colt.
Once I get my PSA upper and finish that build maybe I'll update this thread as a three way. Those always sound good right?
