failure to feed problem
by johnell -
I got this upper and matched it with a FM lower. After about one hundred rounds, I am having feeding problems every one to three rounds. It seems to not strip the round off flush to the bolt face and jams up against the barrel throat.
Soft recoil with sub sonic ammo, runs like a champ
I got this and used a magazine block and it ran great, shooting sub sonic is super fun and the recoil is soft, been shooting steel case and blazer and havent had any issues. Like the handle because I can put it on the right side cuz Im a lefty. Great product, my friends really like shooting it too.
Well Constructed but issues to consider before buying

This is a well built upper, with a unique design for side charging. It is also very light weight with a great handguard. Unfortunately, I had some problems with it. First it doesn't appear to work with with a New Frontier Lower - I've had both first round feeding issues, and may failures to feed that I just can't seem to get 100%. Also the charging handle on the side has a couple issues. First, it appears to have some friction (even after clean/lube) that just won't go away and tends to create issues with mis-feeds on the first round, and they also left a sharp edge of rail next to it - it will eventually cut you. After all that I'm giving up on it, but maybe someone with a different lower will have better luck, and taking the sharp rail edge off with a dremel will prevent it from cutting you so you can fix it pretty easily. So I'm giving it 2 stars still, I'd give it 3 but Foxtrot Mike did not reply to 2 of my inquiries via the web so don't count on them for support either.
