On Friday I received from Valhalla tactical(excellent transaction!!) a freshly manufactured lmt ebcg.this was for my 14.5” pinned and welded colt.
I was a little Leary to spend that kind of money with all the conflicting reviews going back over 10 years,from multiple forums.i was able to find a few threads saying the production from the last couple years run fine in most 16” and shorter carbines.
I took it out and ran the following ammo through the 14.5” colt m4 barrel yesterday.
Wolf 55gr
Tulammo 75 gr
My 62 gr hornady handloads @ 2,900 fps
M193
M855
Federal 55gr brass
I fired 60 rounds of each,no malfunctions of any kind.bolt locked back with surefeed gi mags,pmags (gen 2&3) and lancer mags.
The only things to report are the 75 grain tulammo had almost no recoil,but ran without flaw and m855 felt like it had the same recoil as it did with the standard colt bcg it replaced.as the sun was setting,I was able to see a slight “flash” out of the corner of my eye,I assume from the additional gasses being vented?
The bolt hand cycled a little tougher than any new bolt I have ever used,but smoothed out nicely after the 4th or 5th magazine.
Machine work on the bolt was beautiful,the bolt itself showed plenty of evidence of being test fired.
The carrier showed no evidence of even being in an upper.machine work was evident on areas that had no contact with any other moving parts,the rest of the machine work was impeccable.
Gas key was of the machined type and chrome lined as well as the bore of the carrier itself.
My take away from my experience so far,was this was an excellent purchase for my 14.5” colt m4 profile barreled carbine.i wouldn’t hesitate to buy another if I had the need.the rest of my guns are mid length and seem to be ported appropriately,so thank god for my bank accounts sake I only had one carbine the could benefit from this excellently executed bcg.
I do feel it slightly lightened the recoil impulse and the carbine did feel smoother in operation.
Hope this helps other members considering what most call a waste of money or claim this bcg to be ammo sensitive.
