Ok so I now am the proud owner of 2 colt le 6920's. I am now wanting to look into a full sized. Looking to build a M16a4 clone. So keeping it within milspec whats the best route to go? I know colt makes or at one time made a flat top 20 inch with a a2 flash hider. However it is my understanding they are no longer in production. I'm not wanting to track down something that is no longer made. So for this is my best route going to be BCM?

Try PSA not only do they have a bunch of 20in in stock but they have some built on real FN barrels

Palmetto state armory. Great uppers at an even better price.
