i just picked one of these up in a GB auction and upon closer inspection noticed it had no sling posts. well i found the front adapter, but would like to know if you have to drill the holes for the rear posts. it is the synthetic model, 270 caliber. i haven't gotten the gun yet, just saw it in the pictures.

I recall seeing them when introduced and remarked that the action looked more "M14", but with the same gas system and hardness of receiver metal, I don't know that there is much difference. that said, my dad has had two 740s and both have performed well for 60 years, but then they have been kept clean and lubed. 0 -
They certainly aren't battle rifles made for hundreds of consecutive rounds fired and then a bayonet charge, but for hunting needs that gun should last you a long, long time. 0 -
I've had mine since the early '60,s and it still shoots good. It never let me down in all the years [^] 0 -
Like the 740, and 742, the key to reliability, is keeping it clean, so the dirt and grime, do not help act as an abrasive on the receiver rail. The going to the four lugs, instead of seven, obviously helps do this.
In the same year, they introduced, the 7400, they also introduced the Model Four, which was the upscale version of the 7400. Just the Four had a cartridge head inlay, and fancier wood. My dad had a Model Four, a 740, and several 742's. They were all plagued with the same problem from the conditions he subjected them to, his lack of preventative maintenance(read as failure to keep it clean), and the inherent design flaws.

the 7400 (m-4 also) is much more reliable that the 740/742. It is easyer to clean and will not 'chew' up the receiver rails like a 742/740. It has a hard 'channel' the bolt rides in unlike the 742/740. keep it clean 0 -

Hello Mike, can you tell me some of the typical problems you've had to deal with on the improved 7400's?...I worked on the 742's and also did machining on them and realize the flaws before the enhancements of the 7400...I still read of the difficulties some had on this newer model 7400 and understand many will treat them like a 760 or 7600 as far as cleaning them (which many won't); expecting them to function reliably while filthy, but won't...Were most of your function problems due to cleanliness on this model rather than a poor design of which the 740/742 has?...Remington should have obviously included a barrel nut wrench with that bent chamber brush with all of them..Just received a NIB 7400 which has never been cycled yet,(a 175th anniversary;a shooter not collector) machining it down to a 16" barrel and cutting a 5/8-24 thread with a .825 machined press fit shoulder for a customers suppressor...Would hate to find out it won't feed afterwards all of this like his worn railed 742 did not....Thanks for any response...Mark0 -
"Hello Mike, can you tell me some of the typical problems you've had to deal with on the improved 7400's?.".............well, I'm retired now but general if you keep the 7400's clean and lubed they work well. 0 -
Thanks Mike very comforting to know...Enjoy the retirement I just retired myself a month and a half ago last February.....Good luck..quote:Originally posted by MIKE WISKEY

I had a lot of them come through my shop. A fired case would be stuck in the chamber and rip the extractor out of the bolt.
The chambers are very prone to rust if not religiously kept clean and oiled and that locks the case in.
The Browning BAR is a much better rifle, but as everyone pointed out, the Remington is serviceable if kept spotlessly clean and oiled.0 -
Thats what I've read..I polish the ramp and chamber on these when I have them apart to clean or machining them...The guy I'm doing this one for never has seen a cleaning rod...I give em the speech and after that they're schooled and on their own....quote:Originally posted by p3skyking
