I know from previous discussions here that Colt should be avoided for various reasons.

Does the SP1 also fall into this category?

ETA: If so...can someone refresh my memory on which mfg's to look for in a pre-ban lower....thanx much.

Also...awhile back one of you posted several links to the EE where people had a pre ban lower for sale. If those links could be re-posted I would greatly appreciate it. I have been thru the EE and so far my old eyes have not spied one yet.

There is absolutely nothing wrong with a Colt AR. After all, I doubt anyone has had more experience then them in building the AR15 series of rifles. What has been discussed is the various negatives that come along with the Colt brand. You can find any combination of these:

1) Usually asking a premium price just because it is a Colt.

2) Large front takedown pin that uses the two screws (you need an adapter to use any small hole upper).

3) No protective fence around the mag catch (called a slab-side).

4) Larger than USGI hammer and trigger pins.

5) Hardened block pinned in the lower to prevent insertion of an auto sear and F/A bolt carrier. This means you have to use a carrier that is relieved to clear it.

6) Safety selector switch stops machined off.

If memory serves, the SP1 series will not suffer from numbers 4 and 5 above. Also, the SP1 emulates the original AR15 design, which didn't have a fence around the mag catch (that improvement added after field experience), so it is "correct". Also, if I am still on base, it has a 1 in 12 twist barrel, which makes .22 LR conversion kits a bit more accurate than the faster twists of the later models.

If the price is right, and you can deal with the above, go for it!

Well...I am really only in it for the lower. I guess I just really need to know about the take down holes. I want to put a modern upper on it....with no "adapters".

Then you have to find some company selling a modern upper using big bushing holes .... OR....

Did all models of the older Colts have the large front take down hole?
Link Posted: 10/1/2014 6:13:09 PM EST
No.

I have a colt carbine with the small front hole.

Which model?

I have SP-1s. I use the front offset pin from Brownells. Yeah, you need a screwdriver to remove the upper completely but you can do it in seconds. Never had an issue with it.

Colt lowers are fine. Some have the large trigger pins which if you know you have them is no big deal. All the good triggers are available with large pins. The large take down pin holes can be converted, fore a fee of course. Check out M60Joe.

Here is one for sale. This has the regular size take down pins. With the stock, buffer tube and lower parts kit you have a pretty fair price on this lower.

There are a couple other ads for Pre bans but they are older and not updated so most likely sold.

Yup....went on Olympic Arms site and it shows mfg. date between 5/94 and 8/94. So its about as new as a pre ban can get.
Link Posted: 10/1/2014 9:41:36 PM EST
So what is the exact cutoff date for pre bans?

Must be manufactured prior to 9/13/1994.

Like others have posted, Colts are fine, you just need to be aware of that companies quirks. Personally, I would never pay a premium for a Colt lower, then put more money into having someone modify it, when you can simply by an updated version by another company.

If you can get a 1994 Oly for $450, don't hesitate, just do it. I have one of their early receivers (1980's) and just about every dimension on it is wrong! However, all I have read about the later ones say good things about them.
