I'm looking at buying a complete 6920 OEM1 model soon.

I'm building a mk18 mod 0 clone..

My question as this will be my first ever colt, if I were to sell the completed 6920 lower (plus or minus a stock and trigger guard I could add) what would the value be on that??

Fairly certain this is the route I'm going, but pending lower value I may or may not keep it in the back of the safe.. Just trying to get a better idea..

Much appreciated

I've been looking at GunBroker prices of the LE6920 OEM complete lower half without stock and no trigger guard for the last couple of months and they range from $380 up to $420.

Installing the trigger guard is a risky process, you could break off the ear of the lower receiver at the rear of the trigger guard, if not installed properly.

You don't have to add the trigger guard and stock to your lower half, just sell it as is, less trouble.

It's not risky if there is an effort made to do it properly. As long as the flange is supported, there is no substantial risk of breaking it. A piece of deck board works wonders. A little lubricant on the roll pin and in the holes helps too as well as a little patience and using a 4-8 ounce machinist (ball peen) hammer as opposed to a small sledge :)

I agree it's not a very high risk of failure if done properly, but there are a lot of noobs and you could read them here at ARFCOM frequently maybe around several times a month someone broke the ear of their lower receiver by improperly installing the rear pin of their trigger guard.

Not me, I've been assembling AR since 2005 and had installed several on my Colt and friends and relatives other AR brands, at first I was lubing the pins and using a medium brass hammer on a front sight base synthetic block (with holes for roll pins).

Currently I'm using the vise-grip method taping several layers of tape on the jaws so not to scratch the finish (instructions link below).

For a noob AR owner, I would not recommend them to try installing and removing trigger guard pins until they learn the proper technique and procedures.
