Colt CAR-15 XM177 E2

[OLIAR15]

You should have purchased an original Colt barrel, but most likely would have a 1/7 twist, unless you could source a vintage barrel at 1/12. Many vintage parts are available or repros are available. Also, you need the grenade launcher ring and an original moderator. I can't tell for certain but something looks off on that moderator. I would imagine it would be extremely difficult to get a moderator in Switzerland. Total Silence Inc. in Washington used to make great stuff, stuff you could use to bring that rifle closer to original. Don't know if Tom is still in business.

Well I wanted to keep the 1/12 twist so finding an original Colt barrel in 11.5’ is going to be difficult here in Switzerland.

A previous owner put a CMMG barrel with the wrong twist, length and profile, so the Brownells is an improvement, and I still have the original 10’ barrel (unusable though).

Here are some pictures of the moderator for your consideration. It’s quite heavy and has the chambers inside, unlike a reproduction for cosmetic purposes. I think it may have been repainted, but I suspect the whole rifle might have been repainted also.

It’s a bit banged up on one side

Obviously it’s 4.5’ long. Diameter is close to 1’ and slot length also 1’
