That said, you aren't likely to find those sort of prices any day of the week. Quote HistoryOriginally Posted By krdt:

Based on the OAL and the thread length appearing to match, I think it's reasonably safe to assume the Colt length from the bolt face is the same as well (given acceptable tolerances). It's worth noting that I'm not really equipped to take an extremely precise measurement of the length from the bolt face - I simply dropped a cleaning rod in and taped it off even with the muzzle, then measured. That gave me 10.34375" on two measuring tapes or 10.345" measured on a ruler to 10" and a caliper for the remainder. Either way, it's pretty close to accurate.

Quick update on the status of my replacement KAC RIS rail from Knight's. Here's what Kay in returns/exchanges said:
"Right now the replacement on the RIS Rail is not going to be quick, the only ones that were in stock are the ones that were wrong, so it has to go thru production to have some more made. We will know more about the ETA at a later date." I've currently got two 10.3" ARs without rails at the moment  #ghettolyfe

Quote HistoryOriginally Posted By krdt: The above specs differ slightly from a factory Colt or DD 10.3". Having never taken measurements off a Crane cut barrel, I can't say for absolute certain, but it would appear Crane uses slightly different specs. I took a caliper and measured my DD and Colt 10.3" barrels, and it appears they are cut to the same specs. Here are the measurements I have: Factory DD 10.3": 10.75" OAL, 10.34375" or 10.345" from bolt face*, 2.85" from shoulder to muzzle, .625" thread length Factory Colt 10.3": 10.75" OAL, 2.85" from the shoulder to muzzle, .625" thread length *Note: I only measured the DD 10.3" from the bolt face, as the Colt isn't assembled.

That gave me 10.34375" on two measuring tapes or 10.345" measured on a ruler to 10" and a caliper for the remainder. Either way, it's pretty close to accurate. I've gone from a zero set at 30-40 degrees to an inside temp of 80+ degrees back to 30 degrees, as well as from a zero set at 100+ degrees to 65 degrees indoors back to 115+ degrees without any noticeable zero shift. So, I don't really find it to be a problem. Unless you go from the desert to the artic, it's probably never going to be an issue. FYI, Optics Planet has the EXPS3-0 at $512 shipped after a 10% coupon ;p. I considered it, but I think I'll hold out for sub-$500. I really wish Brownells would put them on sale - can't beat dat lifetime guarantee. |

I got a Colt 6920 that I want to chop up for an Mk18 build.
1. I'm going to end it off to ADCO, seems like my option is to thread the barrel which includes cutting. I'm going to request 10.3": ADCO Threading/Cutting 2. Going to have them open up the gas port to .070". 3. Which Geissele rail are you guys going with? I see some clones here with the Geissele MLOK rails. Thanks! |

The new one is a tad lighter, but I think they'd probably be pretty close to the same shade after some handling. Both this latest URG and the previous one had an inspection date of 12/20/18.  Flash definitely is bringing out more bronze in the above pic than you see in normal light. |
