    Colt carbine lower

    Lower is in spec, great lock up to a colt upper I had built. Only reason for 4 stars is the lower is shown as GI but came with a magpul grip and trigger guard.

    The people at arms unlimited have great customer service,. I’m from Cali and I had emailed them. They responded fast, with the answer I was looking for. The Colt lower was just what I was looking for. They have the best prices on the internet. Keep up the great work.

    Lower is great colt the only reason I’m giving it 4 instead of 5 stars is because this one came with Magpul pistol grip and trigger guard not a huge deal I’ve got others from them that came with all colt milspec parts

    Item is just as advertised. Very well constructed and assembled. CZ/Colt has taken a lot of flak regarding quality, however the fit and finish of this item is excellent and lower parts appear to be mostly what is typical for Colt. Nice product! A bit pricey! Satisfied nonetheless!

    Colt CARBINE lower

    Posted by Justin on 16th Apr 2022

    Good QC, staked castle nut, oiled up enough to fry a turkey (good thing obviously) worth the money…. For this price people are selling stripped lowers. I’ve bought multiple things from armsunlimited and I plan on continuing thanks to the prices and the customer service.
