I would steer clear of them there quality is skecthy at best.
Recommend PSA around the same price and quality is excellent
What about dpms? I've already got a PSA dissipator almost finished just waiting on the upper and a bolt carrier group. I want an 18"SPR or 24" tactical for for longer range shooting with actual optics. BCM also has an 18" option but it's out of stock.
Built my first AR using a Model 1 kit and a Bushmaster lower 15 years ago. Great price. Quick ship. Made a reliable shooter. Not the best parts but fit well together and functioned properly.... Broken extractor @ 2k shooting only brass cases South African surp. Replaced with mil spec extractor and Defender "D" ring. Rifle is still going strong with new owner.
I must have lucked out 2 times,, both my parts kit were great , both shot 1moa at 100 yards with optics,,, I would most definitely buy from model 1 again. Alot of things people say is all here say bs, I know from experience , good price , great product.
