Hope this topic isn't taboo, if it is, mods, please simply delete. After retirement, I am considering returning to the state where four of my grandkids live and where I went to high school and college. That state allows Class III. My current state of residence does not. At this time, I have an opportunity to obtain either an Oly Arms lower or an Essential Arms lower in trade for some parts I no longer use. Would either of these be compatible with a RDIAS or LL if I build a rifle from them in the future? I had a Colt H-BAR, but it had some kind of a block and extra hole and pins. I was told that the RDIAS or LL would not work in that Colt receiver with the block and pins. Is there a list somewhere of which ones have the right geometry and which ones do not? |

I'm pretty sure that the LL will not work. I think the shelf on an oly is too high. Bushmasters work though. Also, if you get a KNS LL protector most lowers will need to be milled a little to accept the link and protector .040 or more if i remember correctly. I know you didn't ask my opinion but of the 2, i'd suggest a RDIAS over a LL because as of yet, you can not run a .22 conversion kit FA with a LL. With the price of ammo these days, shooting .22 is the way to go. Unless you have buckets of money or pallets of .223 already at hand. |
| Ive got a POF 416 gen I lower that works fine with my RLL. I dont have the KNS protector on it tho, but IIRC you only need to cealrence the rear lug on the upper in order for it to fit right. The lower shouldnt need to be touched. CMMG advertises that thered lowers are RDIAS/RLL ready but im pretty sure any low shelf lower wil work fine. Colts do have the stupid sear block in them, i have two with them in it. Unless you get an older SP1 lower, thats what teh RLL's were made for originally. |
| RenegadeX, your point is well taken. For some of us, making several wise choices at the $125 level can eventually lead to the ability to acquire something in the $12-$14 thousand range. Learned the hard way that I make fewer mistakes if I take the time to benefit from the knowledge of others. You are of course correct the value is about 1% of that greater investment. |
