What parts break most often on the AR15? - and why?
My Bushmaster Predator is short stroking and has suffered from the lack of gas always. Gun was bought December 2007 and has now fired 2000 rounds. Last range visit went like this (I used Sellier Bellot 55gr FMJ ammo): - I tried loading magazines with 2 rounds each and firing quick double taps. No problems, the bolt locked back after last round. - I fired around 100-150 rounds and every now and then went to patch the targets. The gun worked well. - Again I tried loading magazines with 2 rounds each and firing quick double taps. First with some magazines the bolt didn´t lock back, then bolt didn´t lock back at all and after that came short stroking with every magazine I had. The gun jams because the locking lugs take a cartridges from the magazine when the cartridge is under the locking lugs, so the bolt clearly doesn´t travel far enough. So far what I´ve checked: - Not a magazine problem. I´m using C-Products aluminum and steel mags and 2008 built Magpul PMAGs - Bolt carrier moves ok in the upper receiver and gas tube as aligned with gas key. - Gas rings seem to be in good contidition and move freely. I also tested putting bolt/bolt carrier on the floor with the bolt head downwards. The bolt doesn´t go inside the carrier (idea from G&A Book of AR15 2008). - Gas key is tight. I haven´t found any leaks. - Gas port size seems to be within specification, I measured 2.35mm (0.0925") with digital caliber. - Gas block is in correct position. - Gas tube is not blocked. - Break Free is used to lubricate moving parts Even the retailer and the gunsmith are puzzled with this rifle and they are running out of options. They said that there was another Bushmaster Predator from the same batch which had the same problems as I´m having now but is now working correctly after some minor tweaking (gas port position problem). Please help me with this gun.
what are the m16 parts that are not suppose to be in a civialians gun?
Do they have the block inside to prevent the installation of M16 trigger parts?
Are Bushmaster carbon 15 parts interchangeable with Professional ordinance Carbon 15 pistols
I saw the "Bushmaster Carbon 15 Type 97S Pistol" on your web site and was wondering if you sell a set instead the complete pistol? I have a M-16 that I would like to convert to a Pistol configuration and wondered if you sell just the parts that configure the " Bushmaster Carbon 15 Type 97S Pistol" as a set. If so, what is the cost? Thanks, Tom
Do you still sell any parts for the M17S? Particularly small parts, pins & springs.
Beware the "Used Gun" or "Used Parts" market
I have a Remington R15, and would like to mount a front fixed folding sight, the forearm tube (top) is not drilled for a rail, the gas block does not seem to be designed for a rail, can the gas block be changed to accept a short rail? If so does Bushmaster sell these parts, what would be the cost? Or can the fore arm tube be drilled for a rail? What does Bushmaster suggest? Have a good day
I am looking for info on the Bushmaster Auto Rifle from the 70's. I have one and need a few small parts. Can you send me a link or any info on the rifle. I can provide a serial number if neccesary. Thanks.
