Too short or too long? I would think too long would cause extra play. I was not able to crank down on the retention cap like on the stock tube, probably should check my barrel too.
I used the bit you recommend. I hit the tube with a MAP torch for 20-30 seconds and the retention screw came right out. I didn't see any loctite residue but something was keeping it stuck.
I am stuck here. My retaining screw will not budge and I am giving it all I have, the slot ears are starting to deform from the torque. Is it possible the screw has loctite applied from the factory? This is an extension purchased from Beneliparts.
Unfortunately I am in California, the Bay Area to be specific. I make purchases for hobby but most people in this area are buying for HD/protection and scrambling to buy whatever they can get. When an M4 pops up for sale at a LGS, even with typical markups, there are a line of people with cash in hand ready to buy. I wished the market would get flooded with Glock 19s so first time buyers and panic buyers leave the more "niche" firearms to the enthusiasts.
Very lucky, congrats. I got an "in-stock" notification from Riflegear this morning on an H20 model but is sold out before I could enter my card info. I still have high-hopes I will score a retail priced M4 even though bitting the bullet on Gunbroker is more and more tempting each day.
I don't think so, I am patiently waiting. I have everything ready to go (7 round tube, US follower, US replacement forearm, Urbino stock, Sync mount and FFT handle).
