I’ve been talking about putting together a GAU-5/A version of the Colt 610 for some time now, long enough that my brother decided it’s time for me to put up, or shutup and gave me a Griffin Armament XM linear comp for my birthday. It’s what he uses on the XM-177 he assembled and it does a pretty good job of sending the muzzle blast down range. He got it for me not long after I mentioned that I liked his well enough that I planned to use it on my project. That sly dog! Looks like I’m committed, now.
The Colt 610 uses a 10" barrel and will be too short to make 16" even with the comp pinned. That means my Gau-5/U project will be an SBR. The 610 uses a partial fence lower and is marked as hown in the following photo from retroblackrifle.com
I’d like to find a partial fence lower that I can have engraved to match. Brownell’s has a partial fence lower, but it’s marked XBRN16E1. Anyone know where I can order a partial fence lower that I can have custom engraved with the GAU-5/A markings and trust info? I would prefer a finished lower, but will consider an 80% lower.
The upper I plan to use is the slickside 10" XM177E1 / GAU-5 from Retro Rilfes https://retrorifles.com/collections/xm-models/products/car-15-upper-xm177-xm177e1
Thanks!
my 60s Colt XM 177E1 dedicated 22 Build is kinda the direction your build should go ( Flat slip ring ) ( Aluminum CAR stock) ( NDS partial fence lower) ( 6 hole skinny Handguards ) ( Colt Slickside 604 type Upper)
