DO NOT BUY THE 770!!!!!!!!!!!!!!!!!!!!!!!!!
I bought one a little while after I came on active duty. I thought "Oh cool, a $400 .308 with a scope. I love my 870s; what a great beginner's rifle Remington is selling based off the 700 action. A couple mags and some ammo makes this undr $500 - that seems like a good deal."
WRONG WRONG WRONG WRONG WRONG!!! DO NOT BUY THE 770!!!!
It lived at my parent's farm since they have some land and a nice area for 500ish yard shots. Well, this piece of shit won't hold a group at anything larger than 50 yards, and this is pretty amazing - I qualify expert with M16 & M4, so I understand the fundamentals of marksmanship. On a good day, I'm happy to have a 8" group at 100 yards with good ammo - those 500 yard targets I setup are more than safe. Hell I'd feel confident standing there watching rounds come in. The base was all mucked up from the factory with a huge gouge. You can't store mags loaded, as after a couple weeks the bottom will bust out - either in the closet or when you fire your first shot on the range - and it will never work right again.
Here's the worst part. At first, I thought it was just a "sticky" action. So I kept shooting it, scrub clean repeat, don't clean, didn't matter. The action got tougher and tougher. Now, to shoot this stupid rifle, I have to carry a section of 2x4 with me to BEAT open the bolt handle. Well, this fall on leave, I call Remington to see what they'll do about it. They told me the 2 year warranty was expired, and they offered to send a shipping label which may be added onto the final repair bill, it would be a fee for them to look at the rifle, and I'd be responsible for all repair costs. Well, that sucks. A rifle I've shot maybe a 500 rounds through is sub-worthless thanks to shoddy manufacturing. Cost savings is all for Remington, not the consumer.
So don't buy it. In case I minced my words: DO NOT BUY A 770. After my experiences, I full and well expect to never buy a new Remington, and will only buy used 870s. I got screwed; don't end up like me.
