Magwell Funnel

[DocMan]

I have a Mil-spec lower (Bushmaster) with the colt style mag adapter. I am looking for a Mag-well designed for the colt style mags. Any help would be appreciated.

I'm not sure you'll find PCC magwells for milspec AR-15 lowers. Magwells are usually made difficult to take on and off in order to keep consistent position for reloads, and the whole point of a mag adapter is to keep the lower versatile. You can imagine how they might not go together.

DocMan- I run Colt mags on a Mil-Spec lower but the lower was cut for 9mm from the get go so the block wasn't needed and after doing a vast a mount of research on magwells came up with a big goose egg. I think your problem may be worse due to the standard receiver and then due to the block going to 9mm. I ended up getting in contact with Bob Novak over at Techwell and he built one for the Mil-Spec. Its on their website under the CMMG label and it turned out perfect. FWIW Bob was great to work with.

Another option,  plus probably quicker and guaranteed a hell of a lot less frustrating, is SMF Tactical has dedicated 9mm Colt lowers and purchase the magwell. Just my 2 cents.

When I ran a Mil-spec lower with a Colt mag adapter, I used this Arredondo AR magwell: https://www.arredondoaccessories.com/product/ar-magwell/
