I use an FA carrier and H buffer and runs great. If I set the piston for suppressed it wont cycle Silver Bear without the can (have not tried other ammo types).

I ran a FA bolt in my 12" piston and it ran fine with an H2 buffer after I broke it in.. On the suppressed setting is would not cycle 223 ammo but would cycle 5.56. With the can on it ran 100% with what ever I ran through it.. I still have the set up, I just prefer the 10'5 a little more so the 12" just sits in the safe.. I added the POF cam pin and it smoothed out the system noticeably..

Older, especially considering the weight savings isn't that great. I wouldn't call it "old" though, they are going to continue to make it.

+1 - I prefer the older MRP-CQB with rails over the slick version.

hey quick question. what torque wrench are yall using?? the one that it came with appears to be cheap and it is too big. any help or links are appreciated.

that is fucking bad ass thanks man

I did not say I have shot the LM8 slick. I just gave a +1 to M4A1's comment a couple of posts above mine to the question about preference between the LM8 and the CQB. I have a CQB but I handled the LM8 at the Shot Show. It is cool but there is not enough weight savings for me to justify any change. Just my simple preference.

Order up one of the factory 300BLK barrels from LMT... they are 16" but with pistol gas. Plan on having it cut to desired length (and port opened) for suppressor you want to run. Will likely need to use a 9mm pistol can (possibly subs only) to fit the internal diameter of the rail. The newer slim uppers actually have a slightly larger internal diameter (I believe 1.46") but I have seen someone post with a 9mm can inside a standard CQB rail. Perhaps you can find a slim Degroat... they are long but if you paired it up with a rifle length upper and say cut the barrel to 6-7" barrel should be really quiet. Liberty Mystic might also work and is user serviceable if you want to run heavy cast subs and get in to clean periodically but they recommend a 9" minimum barrel for running supers.

Don't need a review, called LMT directly. Weight savings is 3.4 ounces between the standard railed CQB MRP and the new LM8.
Decide for yourself if that's a lot of weight.

I spotted an LM8 MWS pass through the shop the other day. Didn't get to handle it much but it was not a lightweight. This model had an 18in barrel, and it sure felt heavier than the 16in MWS that was hanging on the wall.






Overall, unless I get to handle one at the range, I'll stick with the standard MRP uppers.

Once again you bring nothing to table other than I own a standard and it must be better than the LM8 because " I prefer the the standard LMT and also MY FRIENDS at LMT also Prefer the Standard LMT." So here is the problems I see. You comment on why your LMT is so great but you have no actual experience with the slim LMT. You quote sources of MY FRIENDs AT LMT say they prefer the standard LMT MRP but your won't tell who your source is? Does you source actually have experience with how these guns handle or is someone just blowing smoke up your ass about why they consider one better than the other. Once again your not bringing anything other than your own experience with the standard LMT to the table. I have no problem with someone reviewing what they own however I have no tolerance for someone saying a product is better than another product when they don't own or haven't shot that product. It is saying what i have is better because MY FRIENDS AT LMT TELL ME SO. Get over yourself and tell us why you like standard LMT? other than weight. woops you can't because you have never shot a LM8 LMT and can't tell us the difference other than YOUR FRIENDS AT LMT( cough cough bullshit who cares) prefer it so I Should. The person asking the question had a specific question that you answered with nothing to back it up. I like LMT as much as the next guy but I can't read what you are posting with questioning it and wondering why you won't let the product stand on it own merit.
